Elephant tourism often involves cruelty – here are steps toward more humane, animal-friendly excursions

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/michelle-szydlowski-1495781">Michelle Szydlowski</a>, <a href="https://theconversation.com/institutions/miami-university-1934">Miami University</a></em></p> <p>Suju Kali is a 50-year-old elephant in Nepal who has been carrying tourists for over 30 years. Like many elephants I encounter through my <a href="https://doi.org/10.1080/10888705.2022.2028628">research</a>, Suju Kali exhibits anxiety and can be aggressive toward strangers. She suffers from emotional trauma as a result of prolonged, commercial human contact.</p> <p>Like Suju Kali, many animals are trapped within the tourism industry. Some venues have no oversight and little concern for animal or tourist safety. Between 120,000 and 340,000 animals are used globally in a variety of wildlife tourism attractions, including <a href="https://doi.org/10.1371/journal.pone.0138939">endangered species</a> like elephants. Over a quarter of the world’s <a href="https://www.iucnredlist.org/species/7140/45818198">endangered elephants</a> reside in captivity with little oversight.</p> <p>Wildlife tourism – which involves viewing wildlife such as primates or birds in conservation areas, feeding or touching captive or “rehabilitated” wildlife in facilities, and bathing or riding animals like elephants – is <a href="https://doi.org/10.1080/14724049.2022.2156523">tricky business</a>. I know this because I am <a href="https://scholar.google.com/citations?user=YbweA2MAAAAJ&amp;hl=en">a researcher studying human relationships with elephants</a> in both tourism and conservation settings within Southeast Asia.</p> <p>These types of experiences have long been an <a href="https://kathmandupost.com/money/2021/06/17/tourism-is-nepal-s-fourth-largest-industry-by-employment-study">extremely popular and profitable</a> part of the <a href="https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.1002074">tourism market</a>. But now, many travel-related organizations are urging people not to participate in, or <a href="https://www.usatoday.com/story/travel/destinations/2018/04/27/animal-welfare-travelers-how-enjoy-wildlife-without-harming/544938002/">calling for an outright ban on, interactive wildlife experiences</a>.</p> <p>Tourism vendors have started marketing more “ethical options” for consumers. Some are attempting to truly improve the health and welfare of wildlife, and some are transitioning captive wildlife into touch-free, non-riding or lower-stress environments. In other places, organizations are attempting to <a href="https://www.fao.org/documents/card/es/c/b2c5dad0-b9b9-5a3d-a720-20bf3b9f0dc2/">implement standards of care</a> or create manuals that outline good practices for animal husbandry.</p> <p>This marketing, academics argue, is often simply “<a href="https://doi.org/10.1016/j.gecco.2017.11.007">greenwashing</a>,” <a href="http://dx.doi.org/10.1080/13683500.2023.2280704">applying marketing labels to make consumers feel better</a> about their choices without making any real changes. Worse, research shows that some programs marketing themselves as ethical tourism may instead be widening economic gaps and harming both humans and other species that they are meant to protect.</p> <h2>No quick fix</h2> <p>For example, rather than tourist dollars trickling down to local struggling families as intended by local governments, many tourism venues are owned by nonresidents, <a href="http://dx.doi.org/10.3126/japfcsc.v2i1.26746">meaning the profits do not stay in the area</a>. Likewise, only a small number of residents can afford to own tourism venues, and venues do not provide employment for locals from lower income groups.</p> <p>This economic gap is especially obvious in Nepalese elephant stables: Venue owners continue to make money off elephants, while elephant caregivers continue to work 17 hours a day for about US$21 a month; tourists are led to believe they are “<a href="https://www.cabidigitallibrary.org/doi/book/10.1079/9781800624498.0000">promoting sustainability</a>.”</p> <p>Yet, there are no easy answers, especially for elephants working in tourism. Moving them to sanctuaries is difficult because with no governmental or global welfare oversight, elephants may end up in worse conditions.</p> <p>Many kindhearted souls who want to “help” elephants know little about their biology and mental health needs, or what it takes to keep them healthy. Also, feeding large animals like Suju Kali is pricey, <a href="https://doi.org/10.3390/ani14010171">costing around $19,000 yearly</a>. So without profits from riding or other income, owners – or would-be rescuers – can’t maintain elephants. Releasing captive elephants to the jungle is not a choice – many have never learned to live in the wild, so they cannot survive on their own.</p> <h2>Hurting local people</h2> <p>Part of the problem lies with governments, as many have marketed tourism as a way to fund conservation projects. For example in Nepal, a percentage of ticket sales from elephant rides are given to community groups to use for forest preservation and support for local families.</p> <p>Increasing demand for <a href="https://www.routledge.com/Tourism-and-Animal-Ethics/Fennell/p/book/9781032431826">wildlife-based tourism</a> may increase traffic in the area and thus put pressure on local governments to further limit local people’s access to forest resources.</p> <p>This may also lead to <a href="https://www.worldanimalprotection.org/latest/news/un-world-tourism-organisation-urged-create-better-future-animals/">increased demands on local communities</a>, as was the case in Nepal. In the 1970s, the Nepalese government removed local people from their lands in what is now Chitwan National Park as part of increasing “conservation efforts” and changed the protected area’s boundaries. Indigenous “Tharu,” or people of the forest, were forced to abandon their villages and land. While some were offered access to “buffer zones” in the 1990s, many remain poor and landless today.</p> <p>In addition, more and more desirable land surrounding conservation areas in Nepal is being developed for tourist-based businesses such as hotels, restaurants and shops, <a href="http://dx.doi.org/10.3126/japfcsc.v2i1.26746">pushing local poor people farther away</a> from central village areas and the associated tourism income.</p> <p>Some activists would like humans to simply release all wildlife back into the wild, but <a href="https://www.cabidigitallibrary.org/doi/book/10.1079/9781800624498.0000">there are multiple issues</a> with that. Elephant habitats throughout Southeast Asia have been transformed into croplands, cities or train tracks for human use. Other problems arise from the fact that tourism elephants have <a href="https://doi.org/10.4324/9781315457413">never learned</a> how to be elephants in their natural elements, as they were <a href="https://www.pugetsound.edu/sites/default/files/file/8342_Journal%20of%20Tourism%20%282009%29_0.pdf">separated from their herds</a> at an early age.</p> <p>So tourism may be vital to providing food, care and shelter to captive elephants for the rest of their lives and providing jobs for those who really need them. Because elephants can live beyond 60 years, this can be a large commitment.</p> <h2>How to be an ethical tourist</h2> <p>To protect elephants, tourists should check out reviews and photos from any venue they want to visit, and look for clues that animal welfare might be impacted, such as tourists allowed to feed, hold or ride captive wildlife animals. Look for healthy animals, which means doing research on what “healthy” animals of that species should look like.</p> <p>If a venue lists no-touch demonstrations – “unnatural” behaviors that don’t mimic what an elephant might do of their own accord, such as sitting on a ball or riding a bike, or other performances – remember that the behind-the-scenes training used to achieve these behaviors can be <a href="https://doi.org/10.21832/9781845415051-014">violent, traumatic or coercive</a>.</p> <p>Another way to help people and elephant is to to use small, local companies to book your adventures in your area of interest, rather than paying large, international tourism agencies. Look for locally owned hotels, and wait to book excursions until you arrive so you can use local service providers. Book homestay programs and attend cultural events led by community members; talk to tourists and locals you meet in the target town to get their opinions, and use local guides who provide wildlife viewing opportunities <a href="https://nepaldynamicecotours.com/">while maintaining distance from animals</a>.</p> <p>Or tourists can ask to visit <a href="https://www.americanhumane.org/press-release/global-humane-launches-humane-tourism-certification-program/">venues that are certified</a> by international humane animal organizations and that <a href="https://www.su4e.org/">do not allow contact</a> with wildlife. Or they can opt for guided hikes, canoe or kayak experiences, and other environmentally friendly options.</p> <p>While these suggestions will not guarantee that your excursion is animal-friendly, they will help decrease your impact on wildlife, support local families and encourage venues to stop using elephants as entertainment. Those are good first steps.<!-- Below is The Conversation's page counter tag.

Debate sparked over list of top 100 cities on the planet

<p>The best 100 cities on the planet have been revealed, with three Aussie cities making the final list. </p> <p>The list was compiled by as part of an annual report by <a href="https://www.worldsbestcities.com" target="_blank" rel="noopener">Resonance Consultancy</a>, who rated major capital cities on three main factors: liveability, lovability and prosperity, with dozens of factors taken into account.</p> <p>These include educational attainment, GDP per capita, poverty rate, the number of quality restaurants, shops and nightclubs, walkability, the number of mapped bike routes, quality parks and museums, as well as ratings from TripAdvisor and Google. </p> <p>The top ten chart features four cities on the Asian continent, four in Europe and two in the U.S.</p> <p>Sydney, Melbourne and Brisbane were all featured in the list, coming in at numbers 31, 35 and 57 respectively.</p> <p>Taking out the number one spot this year is London, dubbed the "capital of capitals" that "reigns over all global cities" as the best metropolis in the world. </p> <p>The study proclaims it as the most liveable and the most lovable mecca, solidified by its winning culture and education attainment.</p> <p>The report concludes, "Despite crippling Covid lockdowns and economic devastation. Despite Brexit. Despite a war in Europe. The city is more indomitable and part of the global discourse than ever.

Handkerchief or tissue? Which one’s better for our health and the planet?

<p><em><a href="https://theconversation.com/profiles/mark-patrick-taylor-11394">Mark Patrick Taylor</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a> and <a href="https://theconversation.com/profiles/hester-joyce-122106">Hester Joyce</a>, <a href="https://theconversation.com/institutions/la-trobe-university-842">La Trobe University</a></em></p> <p>Maybe you have hay fever, COVID, a cold or the flu, and are reaching for a tissue or handkerchief.</p> <p>But which one’s better at stopping infections spreading? Which has a smaller environmental impact? Is it the hanky, which has been with us since at least Roman times? Or the more recent and widely-used paper tissue?</p> <p>You might be surprised at the results.</p> <h2>A short history of the handkerchief and tissue</h2> <p>Today, we think of hankies as something to wipe noses, and catch coughs and sneezes. But such a simple square of cloth has a complex history.</p> <p>In the first century, the Romans <a href="http://margaretroedesigns.com/wp-content/uploads/HandkerchiefHist.pdf">used</a> a <em>sudarium</em> (Latin for sweat cloth) to wipe off sweat, or to mask the mouth and face.</p> <p>Over time, people have used what we now call a handkerchief or hanky, as a head covering, as a veil and for disguise, to clean hands, for wounds and to staunch blood.</p> <p>Wealthy people have used them to signify class and manners, and for discretely wiping away phlegm rather than smearing snot on sleeves or down skirts. Royalty have used them to indicate wealth and power through their gifts of fine linen and silk handkerchiefs to favoured subjects. Henry VIII owned an extensive collection, some embossed with gold and silver.</p> <p>Handkerchiefs have also been <a href="https://www.bl.uk/collection-items/italian-handkerchief">markers of</a> love, fidelity and sexual preferences. In the late 19th century the “handkerchief code” was a system of colour coding and handkerchief placement used to indicate sexual preferences, <a href="https://www.refinery29.com/en-au/lgbtq-secret-handkerchief-code-language">which is still active</a> in LGBTQ+ communities today.</p> <p>We can <a href="https://www.euppublishing.com/doi/epub/10.3366/cult.2020.0214">trace the origins</a> of paper tissue to China in the 2nd century BC. But it wasn’t until the 1920s that tissue as we know it today <a href="https://www.kleenex.co.uk/kleenex-history">was developed</a> to remove make-up and wipe runny noses from hay fever.</p> <h2>So, which one is better for our health?</h2> <p>More than 100 years ago, a cloth hanky was considered a “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5248216/pdf/hosplond73063-0008b.pdf">little flag of Death</a>” because of the germs it carried and how it contaminated pockets it was left in. Later, we were urged to use a hanky <a href="http://resource.nlm.nih.gov/101449736">as</a> “coughs and sneezes spread diseases”.</p> <figure class="align-right zoomable"><figcaption></figcaption></figure> <p>Today, we know nasal secretions harbour cold-type viruses that can be <a href="https://onlinelibrary.wiley.com/doi/10.1002/jmv.22027">transferred</a> to a <a href="https://www.abc.net.au/health/talkinghealth/factbuster/stories/2011/06/02/3231404.htm">range of surfaces</a> – hands, handkerchiefs, tissues, door knobs, keyboards – sometimes surviving <a href="https://doi.org/10.1093/oxfordjournals.aje.a113473">long after</a> the initial exposure.</p> <p>So blowing your nose into a reusable cotton hanky, then touching another object, means these viruses can spread. Even if you put your cotton hanky in the wash immediately, you’d likely contaminate surfaces on the way, such as doorknobs, and use your infected hands to operate the washing machine.</p> <p>Viruses don’t tend to <a href="https://doi.org/10.1093/infdis/146.1.47">survive so long</a> on tissues. As long as you throw tissues away after using them, and don’t leave them lying around for others to pick up, the chance of passing germs to others from a used tissue is far lower.</p> <p>Then there’s the question of whether hankies or tissues are effective barriers to coughing and respiratory spray.</p> <p>Basic cloth coverings, such as handkerchiefs or bandannas, can catch sputum, as can tissues. But several studies have shown they do not effectively <a href="https://doi.org/10.1021/acs.nanolett.0c02211">filter</a> <a href="https://aaqr.org/articles/aaqr-13-06-oa-0201.pdf">respiratory aerosols</a>, or <a href="https://doi.org/10.1177/153567601001500204">stop you inhaling</a> pollutants, pathogens or <a href="https://doi.org/10.1016/j.ijheh.2018.03.012">small airborne particles</a>.</p> <h2>Which one is better for the planet?</h2> <p>If you want to look at environmental considerations, US company Ecosystem Analytics <a href="https://ecosystem-analytics.com/wp-content/uploads/2013/10/Complete-LCA-Facial-Tissue-Handkerchief.pdf">compared</a> resusable cotton hankies to disposable paper tissues using a <a href="https://doi.org/10.1007/BF02978505">lifecycle analysis</a>. It considered four measures of environmental impacts associated with production, transport, use and disposal:</p> <ul> <li> <p>climate change (sum of greenhouse gases: carbon dioxide, methane, water vapour, nitrous oxide and CFCs)</p> </li> <li> <p>ecosystem quality (chemical pollution of land and water)</p> </li> <li> <p>human health (carcinogenic and non‐carcinogenic toxicity to humans)</p> </li> <li> <p>resources (total energy requirements of non‐renewable energy and mineral extraction).</p> </li> </ul> <p>The verdict? Across the four measures, a cotton hanky had five to seven times greater impact than an equivalent tissue.</p> <p>And, by far, the greatest impacts were related to the production of each of these products, rather than using or disposing of them.</p> <p>If you’re still keen to use a cotton hanky, you could opt for organic cotton, which has a <a href="https://www.sei.org/publications/ecological-footprint-water-analysis-cotton-hemp-polyester/">lower ecological footprint</a> compared to standard cotton produced in the same location. But organic cotton production has <a href="https://www.nytimes.com/wirecutter/blog/is-organic-cotton-better-for-the-environment/">lower yields</a> than its conventional equivalent, meaning more land is needed to produce an equivalent amount, compounding the total environmental impact.</p> <p>If you want to feel better about using tissues, ones made from recycled material may be a better option. Their manufacture leads to <a href="https://doi.org/10.1007/s11367-013-0597-x">fewer</a> greenhouse gas emissions compared with making regular tissues.</p> <h2>The verdict</h2> <p>Wiping our noses with paper tissues we dispose of properly after use (and don’t store in our pocket), made from recycled material, is preferable from both a health and environmental perspective.</p> <p>But tissues don’t quite have the same panache as the historic and versatile cloth hanky.<!-- Below is The Conversation's page counter tag.

Yet human activities in the current era, sometimes called the “<a href="https://theconversation.com/did-the-anthropocene-start-in-1950-or-much-earlier-heres-why-debate-over-our-world-changing-impact-matters-209869">Anthropocene</a>”, are reshaping patterns of fire across the planet.</p> <p><a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-environ-120220-055357">In our new research</a>, published in the Annual Review of Environment and Resources, we used satellite data to create global maps of where and how fires are burning. We calculated about 3.98 million square kilometres of Earth’s land surface burns each year. We also examined research spanning archaeology, climatology, ecology, Indigenous knowledge and paleoecology, to better understand the causes and consequences of fires.</p> <p>Our international team found strong evidence fires are burning in unexpected places, at unusual times and in rarely observed ways. These changes in fire patterns are threatening human lives and modifying ecosystems.</p> <p>But the future does not have to be bleak. There are many opportunities to apply knowledge and practice of fire to benefit people and nature.</p> <h2>Here’s how fire patterns are changing</h2> <p>Exploring multiple approaches and scales enables a deeper understanding of where, when and how fires burn.</p> <p>Satellite data provide evidence of changes in fire patterns at a global scale. <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2020RG000726">Annual fire season length</a> increased by 14 days from 1979 to 2020 and <a href="https://www.nature.com/articles/s41586-021-04325-1">night fires</a>, which indicate fires that cannot be quickly controlled, increased in intensity by 7.2% from 2003 to 2020.</p> <p>Other changes are apparent only when we look at data from particular regions. An increase in fire size and the frequency of large fires has recently been observed in <a href="https://www.pnas.org/doi/abs/10.1073/pnas.2103135118">forests and woodlands of the western United States</a>. Meanwhile fire-dependent grasslands and savannahs across <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/gcb.14711">Africa</a> and <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2019GL082327">Brazil</a> have experienced reductions in fire frequency.</p> <p>It’s also important to consider the timescale and type of fire when interpreting changes. In Australia, <a href="https://www.nature.com/articles/s41467-021-27225-4">satellite records show</a> the frequency of very large forest fires has increased over the past four decades. At longer time scales, <a href="https://link.springer.com/article/10.1007/s13280-020-01339-3">charcoal and pollen records</a> indicate the frequency of low-intensity fires <a href="https://esajournals.onlinelibrary.wiley.com/doi/10.1002/fee.2395">decreased in parts of southeastern Australia</a> following British colonisation in 1788.</p> <h2>Changes in fire affect air, land and water</h2> <p>Many animals and plants have evolved strategies that enable them to thrive under particular fire patterns. This means changes to fire characteristics can <a href="https://www.science.org/doi/10.1126/science.abb0355">harm populations and ecosystems</a>.</p> <p><a href="https://conbio.onlinelibrary.wiley.com/doi/full/10.1111/conl.12905">Large and intense fires</a> are reducing the available forest habitat preferred by the greater glider. But a <a href="https://theconversation.com/research-reveals-fire-is-pushing-88-of-australias-threatened-land-mammals-closer-to-extinction-185965">lack of fire can be problematic too</a>. Threatened species of native rodents can benefit from food resources and habitats that flourish shortly after fire.</p> <p>There is evidence that emissions from recent fires are already modifying the atmosphere. The historically exceptional 2019–20 Australian wildfires produced <a href="https://www.science.org/doi/10.1126/science.abe1415#:%7E:text=Intense%2C%20widespread%20bushfires%20in%20Australia,from%20a%20moderate%20volcanic%20eruption.">record-breaking levels of aerosols</a> over the Southern Hemisphere, as well as substantial carbon emissions.</p> <p>The <a href="https://www.nature.com/articles/s41893-020-00610-5">wildfire smoke-related health costs</a> of the 2019–20 wildfires in Australia included an estimated 429 smoke-related premature deaths as well as 3,230 hospital admissions for cardiovascular and respiratory disorders.</p> <p>Changes in fire patterns are modifying water cycles, too. In the western United States, <a href="https://www.pnas.org/doi/10.1073/pnas.2009717118">fires are reaching higher elevations</a> and having strong impacts on <a href="https://www.pnas.org/doi/10.1073/pnas.2200333119">snow</a> and water availability.</p> <p>New studies are revealing how the air, land and water that support life on Earth are connected by fires. Smoke plumes from the 2019–20 Australian wildfires transported nutrients to the Southern Ocean, resulting in <a href="https://www.nature.com/articles/s41586-021-03805-8">widespread phytoplankton blooms</a>.</p> <h2>Humans are responsible for the changes</h2> <p>Human drivers such as climate change, land use, fire use and suppression, and transportation and extinction of species <a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-environ-120220-055357">are causing shifts in fire patterns</a>.</p> <p>Increasing global temperatures and more frequent heatwaves and droughts increase the likelihood of fire by promoting hot, dry and windy conditions. A pattern of extreme fire weather outside of natural climate variation is already emerging in <a href="https://onlinelibrary.wiley.com/doi/10.1111/gcb.15388">North America</a>, <a href="https://link.springer.com/article/10.1007/s10584-014-1183-3">southern Europe</a> and <a href="https://iopscience.iop.org/article/10.1088/1748-9326/ac1e3a/meta">the Amazon basin</a>.</p> <p>Humans modify fire regimes by changing land use for agricultural, forestry and urban purposes. Until recent decades, large fires in tropical forests were uncommon. But <a href="https://www.nature.com/articles/s41586-021-03876-7">deforestation fires</a> used to clear primary forest for agriculture often promotes more frequent and intense uncontrolled fires.</p> <p>Humans have transported plants and animals across the globe, resulting in novel mixes of species that modify fuels and fire regimes. In many parts of the world, <a href="https://www.pnas.org/doi/abs/10.1073/pnas.1908253116">invasive grasses</a> have increased flammability and fire activity.</p> <p>Social and economic changes propel these drivers. Colonisation by Europeans and the displacement of Indigenous peoples and their skilful use of fire has been linked with fire changes in <a href="https://esajournals.onlinelibrary.wiley.com/doi/10.1002/fee.2395">Australia</a>, <a href="https://www.pnas.org/doi/10.1073/pnas.2116264119">North America</a> and <a href="https://royalsocietypublishing.org/doi/10.1098/rstb.2015.0174">South America</a>.</p> <h2>Using knowledge and practice of fire to achieve sustainability goals</h2> <p><a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-environ-120220-055357">The pace and scale of these changes</a> represent challenges to humanity, but knowledge and practice of fire can help to achieve sustainability goals.</p> <p>This includes:</p> <ul> <li><a href="https://royalsocietypublishing.org/doi/10.1098/rstb.2015.0174">good health and wellbeing</a>, by supporting community-owned solutions and fire practices that increase social cohesion and health</li> <li><a href="https://www.sciencedirect.com/science/article/pii/S0301479718314658">sustainable cities and communities</a>, by designing green firebreaks and mixed-use areas with low fuels, strategically located in the landscape</li> <li><a href="https://www.science.org/doi/10.1126/science.aam7672">life on land</a>, by tailoring use of fire to promote and restore species and ecosystems</li> <li><a href="https://www.nature.com/articles/s41561-021-00867-1">climate action</a>, by applying low-intensity fire to promote the stability of soil organic matter and increase carbon storage</li> <li><a href="https://www.mdpi.com/1660-4601/18/8/3921">reduced inequalities</a>, by allocating resources before, during, and after wildfires to at-risk communities and residents.</li> </ul> <p>As the world changes, society as a whole needs to keep learning about the interplay between people and fire.</p> <p>A deep understanding of fire is essential for achieving a sustainable future – in other words, <a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-environ-120220-055357">a better Anthropocene</a>.<!-- Below is The Conversation's page counter tag.

7 tips to help turn your cat into a friendly member of the family

<p><strong>How to make your cat love you</strong></p> <p>Getting a cat to be more affectionate is the yearning of many a pet owner. Some cats are antisocial when it comes to being picked up, cuddled or petted (much less sitting in a person’s lap). Other kitties are born loving this sort of attention.</p> <p>If you’re not lucky enough to have a cat who automatically seeks out your affection, trying to entice that reclusive furball to become your snuggle buddy may take some motivation and determination on your part. Your pet may never convert to a drooly lap cat, even after weeks of effort on your part, but at the very least you’ll probably strengthen your relationship with your cat.</p> <p><strong>Get the basics down</strong></p> <p>The initial stage of coaxing a cat into being more lovable is to let her recognise your positive intentions by dependably offering her good food, clean water, fun toys to play with and a litterbox that is cleaned regularly. When she’s happier, you’ll be happier, and these mutual good feelings will carry over into your relationship together.</p> <p>Spend extra time with your cat, letting her see you not as her owner but as her friend, meal provider and guardian. If she’s not coming up to you to say hi, be proactive: Walk over to her (as long as she’s not super-shy) and lavish affection on her. Once she gets used to all this attention, she might very well start seeking it out from you.</p> <p><strong>Be affectionate while feeding </strong></p> <p>While preparing her food (or making a production of opening that can of food), talk to your kitty. When she begins eating, gently stroke her a few times. This will help her associate being petted with a positive experience.</p> <p><strong>Be playful </strong></p> <p>Instead of trying to force a hug from your reluctant cat, play with her a little, maybe getting her to paw at a piece of string or chase after a laser pointer.</p> <p><strong>Try a little catnip</strong></p> <p>Bringing out a tin of catnip often brings timid felines out of their shells, and aloof cats sometimes become far friendlier under the influence of catnip.</p> <p><strong>Use the "slow blink"</strong></p> <p>Remember that using the “slow blink” as a non-verbal statement saying “I love you” will go a much longer way with your cat, versus a direct stare, which she may take as a threat.</p> <p><strong>Don't chase</strong></p> <p>Don’t try to push affection on your cat – for example, running after her. This might work with a dog, but chasing usually causes a scaredy cat to jolt off in another direction feeling victimised. And I should hope it goes without saying, but don’t punish or yell at your shy cat.</p> <p><strong>Give them a treat</strong></p> <p>Each time you share a session of tenderness with your cat, give her a treat. Let her see that this affectionate behaviour has its rewards.</p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/pets/7-tips-to-make-your-cat-more-friendly" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

7 ulcer-friendly foods to help soothe your stomach

<p><strong>Honey is one of the best ulcer-friendly foods</strong></p> <p>Modern medicine has finally caught on to a folk remedy that’s been used for centuries. Because honey fights bacteria, hospitals and clinics sometimes apply it to burns and other open wounds. For the same reason that it can help heal a skin ulcer, honey may help thwart H. pylori.</p> <p>Researchers from New Zealand tested honey made from the nectar of the Manuka flower on bacteria from biopsies of gastric ulcers and found that the honey inhibited bacterial growth, making it one of the most effective ulcer-friendly foods. Other researchers have been successful in using other types of honey to halt the growth of H. pylori.</p> <p><span style="text-decoration: underline;"><em>Recommended dose</em></span>: Start by taking a tablespoon of honey in the morning and at night to calm a fiery belly. Spread it on toast or a cracker to keep it in the stomach longer. Because H. pylori is slow growing, be sure to keep up your honey regimen until ulcer symptoms are long gone.</p> <p><strong>Broccoli, brussels sprouts, cauliflower and kale are all ulcer-friendly foods</strong></p> <p>These cruciferous vegetables all contain sulforaphane, a compound that appears to squelch H. pylori. In one study, after patients who tested positive for the bacteria ate a half cup of broccoli sprouts twice daily for seven days, 78 per cent tested negative for the bacteria. Other studies, on mice, have shown that sulforaphane extracts can successfully destroy the bacteria in the mice’s digestive tracts.</p> <p><span style="text-decoration: underline;"><em>Recommended dose</em></span>: Consider eating a cup a day of broccoli, raw or cooked, or broccoli sprouts. Not only will the broccoli begin to battle your ulcer, but it will also provide more than a day’s worth of vitamin C and a generous amount of fibre: two more allies in the fight against ulcers.</p> <p><strong>Cabbage</strong></p> <p>Scientists think that it may be the amino acid glutamine that gives cabbage its anti-ulcer punch. Glutamine helps to fortify the mucosal lining of the gut and to improve blood flow to the stomach, meaning it not only helps prevent ulcers but can also speed healing of existing sores.</p> <p><span style="text-decoration: underline;"><em>Recommended dose</em></span>: Eat two cups of raw cabbage daily. Add it to salads, coleslaw, and wraps. You can also drink raw cabbage juice, sold in health food stores. Drink a quart a day for three weeks if – you can stand it!</p> <p><strong>Yoghurt with active cultures</strong></p> <p>Foods like yoghurt and kefir (fermented milk) contain “good bacteria” that can inhibit H. pylori and may help ulcers heal faster. In one large study in Sweden, people who ate fermented milk products like yoghurt at least three times a week were much less likely to have ulcers than people who ate yoghurt less often.</p> <p><span style="text-decoration: underline;"><em>Recommended dose</em></span>: Have a cup of yoghurt, kefir, or another fermented milk product with live, active cultures at least once a day. Avoid sweetened varieties, which are less effective</p> <p><strong>Plantain is among the best ulcer-friendly foods</strong></p> <p>This large, green, banana-like fruit is starchy and sticky in texture. It helps to soothe inflamed and irritated mucous membranes and has some antibacterial properties to boot. Studies on rats with ulcers caused by daily aspirin use have shown that unripe green plantain can both prevent the formation of ulcers and help to heal them. Plantain works its magic best when it’s unripe.</p> <p><span style="text-decoration: underline;"><em>Recommended dose</em></span>: Until human studies determine the amount that might help, use the fruit as they do in Latin America, where green plantain is eaten boiled like a potato. Avoid fried plantain, as the fat can aggravate ulcers.</p> <p><strong>Fruits, vegetables, whole grains and other high-fibre foods </strong></p> <p>Add another star to fibre’s crown. Besides keeping you regular, fibre has a role in keeping ulcers at bay, especially those in the duodenum. A number of studies have found that people who eat high-fibre diets have a lower risk of developing ulcers. A study in the American Journal of Epidemiology looked at the diets of 47,806 men and found that those who ate 11 grams or more of fibre from vegetables had a 32 per cent lower risk of developing duodenal ulcers.</p> <p>Scientists aren’t sure how fibre helps, but it may be thanks to the fact that it slows the emptying of the stomach and thus reduces the amount of time the stomach lining and duodenum are exposed to digestive acids. Soluble fibre, the kind found in oats, beans, barley, peas, and pears, also forms a slippery goo in the stomach that acts as a barrier between the stomach lining and corrosive stomach acids.</p> <p><span style="text-decoration: underline;"><em>Recommended dose</em></span>: General health guidelines suggest getting 25 to 35 grams of fibre a day.</p> <p><strong>Slippery elm tea</strong></p> <p>Slippery elm coats the stomach just as it does a sore throat, bringing some relief, albeit short-lived, from ulcer pain.</p> <p><span style="text-decoration: underline;"><em>Recommended dose</em></span>: Several cups throughout the day.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/7-ulcer-friendly-foods-to-help-soothe-your-stomach" target="_blank" rel="noopener">Reader's Digest</a>.  </em></p>

If the world were coming to an end, what would be the most ethical way to rebuild humanity ‘off planet’?

<p><em><a href="https://theconversation.com/profiles/evie-kendal-734653">Evie Kendal</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>Last week, scientists announced that for the first time on record, Antarctic ice has failed to “substantially recover” over winter, in a “once in 7.5-million-year event”. Climate change is the <a href="https://theconversation.com/antarctica-is-missing-a-chunk-of-sea-ice-bigger-than-greenland-whats-going-on-210665">most likely culprit</a>.</p> <p>Petra Heil, a sea ice physicist from the Australian Antarctic Division, <a href="https://www.abc.net.au/news/2023-07-24/antarctic-sea-ice-levels-nosedive-five-sigma-event/102635204">told the ABC</a> it could tip the world into a new state. “That would be quite concerning to the sustainability of human conditions on Earth, I suspect.”</p> <p>And in March, a senior United Nations disarmament official <a href="https://press.un.org/en/2023/sc15250.doc.htm">told the Security Council</a> the risk of nuclear weapons being used today is higher than at any time since the end of the Cold War.</p> <p>Both warnings speak to concerns about Earth’s security. Will our planet be able to support human life in the future? And if not, will humanity have another chance at survival in space?</p> <h2>‘Billionauts’ and how to choose who goes</h2> <p>Over the past few years, we’ve witnessed the rise of the “billionaut”. The ultra-wealthy are engaged in a <a href="https://theconversation.com/billionaire-space-race-the-ultimate-symbol-of-capitalisms-flawed-obsession-with-growth-164511">private space race</a> costing billions of dollars, while <a href="https://www.forbes.com/sites/oliverwilliams1/2021/12/21/billionaire-space-race-turns-into-a-publicity-disaster/?sh=79056f7e5e4d">regular citizens often condemn</a> the wasted resources and contribution to global carbon emissions.</p> <p>Space – described in the <a href="https://www.unoosa.org/oosa/en/ourwork/spacelaw/treaties/introouterspacetreaty.html">Outer Space Treaty</a> as being the “province of all mankind” – risks instead becoming the playground of the elite few, as they try to escape the consequences of environmental destruction.</p> <p>But if we have to select humans to send into space for a species survival mission, how do we choose who gets to go?</p> <p>In Montreal last month, the <a href="https://irg.space/irg-2023/">Interstellar Research Group</a> explored the question: how would you select a crew for the first interstellar mission?</p> <p>A panel led by <a href="https://www.erikanesvold.com/">Erika Nesvold</a>, a co-editor of the new book <a href="https://global.oup.com/academic/product/reclaiming-space-9780197604793?cc=au&amp;lang=en&amp;">Reclaiming Space</a>, discussed the perspectives of gender minorities, people with disabilities and First Nations groups regarding the ideal composition for an off-world crew.</p> <p>I was on the panel to discuss my contribution to the book, which explores how we can promote procreation in our new off-world society, without diminishing the reproductive liberty of survivors.</p> <h2>The ultra-wealthy and reproductive slavery</h2> <p>The first step in deciding how to allocate limited spaces on our “lifeboat” is identifying and rejecting options that are practically or ethically unacceptable.</p> <p>The first option I rejected was a user-pay system, whereby the wealthy can purchase a seat on the lifeboat. A 2022 Oxfam report showed the investments of just 125 billionaires collectively contribute 393 million tonnes of carbon dioxide equivalent per year: <a href="https://www.oxfam.org/en/press-releases/billionaire-emits-million-times-more-greenhouse-gases-average-person#:%7E:text=Recent%20data%20from%20Oxfam's%20research,%C2%B0C%20goal%20of%20the">a million times more</a> than the average for most global citizens.</p> <p>If the ultra-wealthy are the only ones to survive an environmental apocalypse, there’s a risk they would just create another one, on another planet. This would undermine the species survival project.</p> <p>The second option I rejected was allowing a reproductive slave class to develop, with some survivors compelled to populate the new community. This would disproportionately impact cis-gender women of reproductive capacity, demanding their gestational labour in exchange for a chance at survival.</p> <p>Neither a user-pay system nor reproductive slave labour would achieve the goal of “saving humanity” in any meaningful way.</p> <p>Many would argue preserving human values - including equality, reproductive liberty, and respect for diversity - is more important than saving human biology. If we lose what makes us unique as a species, that would be a kind of extinction anyway.</p> <p>But if we want humanity to survive, we still need to build our population in our new home. So what other options do we have?</p> <h2>Reproduction and diversity</h2> <p>How can we avoid discrimination on the basis of reproductive capacity – including age, sexuality, <a href="https://theconversation.com/infertility-through-the-ages-and-how-ivf-changed-the-way-we-think-about-it-87128">fertility status</a> or personal preference?</p> <p>We could avoid any questions about family planning when selecting our crew. This would align with <a href="https://www.seek.com.au/career-advice/article/illegal-interview-questions-what-employers-have-no-right-to-ask">equal opportunity policies</a> in other areas, like employment. But we would then have to hope enough candidates selected on other merits happen to be willing and able to procreate.</p> <p>Alternatively, we could reserve a certain number of places for those who agree to contribute to population growth. Fertility would then become an inherent job requirement. This might be similar to taking on a role as a <a href="https://theconversation.com/surrogacy-laws-why-a-global-approach-is-needed-to-stop-exploitation-of-women-98966">surrogate</a>, in which reproductive capacity is essential.</p> <p>But what if, after accepting such a position on the mission, someone changed their mind about wanting children? Would they be expected to provide some sort of compensation? Would they be vulnerable to retaliation?</p> <p>The more we focus on procreation, the less diversity we will preserve in the species as a whole – especially if we deliberately select against diverse sexualities, disabilities and older people.</p> <p>A lack of diversity would also threaten the long-term viability of the new society. For example, even if we exclude all physiologically or socially infertile people from the initial crew, these traits will reappear in future generations.</p> <p>The difference is: these children would be born into a less accepting community. Cooperation will be essential for the new human society – so promoting hostility would be counterproductive.</p> <p>So, what options are left? Using a random global sample to select travellers might alleviate concerns about equity and fairness. But the ability of a random sample to maximise our survival as a species would depend on how large the sample can be.</p> <p>A global sample would minimise bias. But there’s a risk it might yield a crew without doctors, engineers, farmers or other essential personnel.</p> <h2>Random selection versus a points-based system</h2> <p>The best balance between competing needs might be a stratified random sampling method, involving randomly selecting survivors from predetermined categories. Reproductive potential might be one category. Others might focus on other elements of practical usefulness or contribution to human diversity.</p> <p>Another option is a points-based system, whereby different skills and characteristics are ranked in terms of their desirability. In this system, an elderly person who speaks multiple languages may score higher than a physiologically fertile young person, due to their ability to substantially contribute to language preservation and education.</p> <p>This does not entirely eliminate the potential for discrimination, of course.

The 7 most addictive (and delicious) foods on the planet

<p><strong>Why we can't get enough</strong></p> <p>What is it about the three Cs: Chocolate, cheese and chips? For some reason, we can never get enough of them. But wanting to chow on a particular food is one thing, being addicted to it is another. Fact is, you can become addicted to a certain food, and you can blame your brain’s response to it. That’s because certain foods elicit a release of dopamine in the brain, which can lead to more cravings for that particular treat, especially when it comes to foods that are high in sugar, salt and/or fat. Addictive foods are ones that hit your brain right in its pleasure centre, ostensibly telling you that you need more, more, more.</p> <p>“When this pleasure/reward centre is stimulated, the brain starts secreting dopamine and other chemicals that make us enjoy the experience even more,” says registered dietitian Ashvini Mashru. “Because your brain loves the sensation caused by that dopamine release, it seeks more of it by creating cravings, that if listened to can cause a vicious cycle of addiction.”</p> <p><strong>Chocoholics take note</strong></p> <p>That bowl of Smarties sitting on your colleague’s desk is a delicious temptation, a crunchy chocolatey treat that’s hard to resist. What we know is that chocolate is one of the most addictive foods around because it binds to the same pleasure centres in the brain as alcohol and certain drugs, according to a 2011 study conducted by Drexel University.</p> <p>It also boasts a nice ‘mouth feel’, which stimulates oxytocin production, another feel-good hormone, according to Dan DeFigio, author of Beating Sugar Addiction for Dummies. “Over time, our brains start looking for that dopamine hit, and every time we eat chocolate, it reinforces that ‘wiring,’” he says.</p> <p><strong>More cheese please</strong></p> <p>If you’ve hovered over a cheese platter and piled up the cubes, you’ll be relieved to know that it’s not just you. Cheese, which is generally high in fat and cholesterol, also contains a substance called casomorphin that binds to the opioid or feel-good receptors in the brain.</p> <p>“Casomorphins attach to neurotransmitters in our brains and release dopamine, feel-good chemicals, that often lead us to wanting more,” says Dr Neal Barnard, author of The Cheese Trap. “While cheese does have its health benefits, it also can be seriously addictive.”</p> <p><strong>Carb fix</strong></p> <p>Reach into that bowl of potato chips, tortilla chips or pretzels over and over again, and you’ll know something is happening on the addiction front. And, while there’s no particular compound in these foods that bind to specific brain receptors to cause a euphoric, stimulating, or addictive behaviour, there’s something else at play.</p> <p>“Simple carbohydrates are seen as ‘addictive’ because they cause a quick glucose release, and this quickly increases a person’s energy, says nutritionist Celina Jean. “This energy will quickly be used up, and then you’ll be forced to eat more simple carbohydrates to keep your blood sugar raised.”</p> <p><strong>Oh, sweet sips</strong></p> <p>Not only do sugary soft drinks (including sweet tea) provide us with very little nutrients, but one 375mL can contain a staggering 43 grams of sugar. Like sugary treats, fizzy drinks can stimulate the release of dopamine. Add caffeine and you’re getting a double-energy hit.</p> <p>“Once you’re hooked on caffeine, you can suffer symptoms of withdrawal if you try to stop, including sluggishness, headaches and emotional distress,” says Mashru.</p> <p><strong>Pass the fries</strong></p> <p>Hot chips or French fries are typically crisp, hot and salty. This is a triple-threat that signals the tongue and the brain to eat more, Mashru says. The fat content in fries triggers receptors in our mouths that send a signal to our brain and gut reinforcing the desire to eat more.</p> <p>“These little potato sticks are also a comfort food,” Mashru says. “Therefore, every time you go through the line in a restaurant and see them on the menu, you may find the urge to order them as a side to your entrée irresistible.”</p> <p><strong>Ice cream, you scream</strong></p> <p>Cravings for ice cream can be insatiable – it’s all about the sugar content and creamy texture, and researchers agree that foods like ice cream, which is basically cream and milk, stimulate the brain in the same way drugs do, inducing behaviours that resemble addiction, says dietitian Keri Glassman.</p> <p>“The sugar ‘highs’ and ‘lows’ you experience are consistent with sugar ‘dependency’,” she says. “When your body gets used to sugar, you feel out of sorts when you consume less, which causes you to eat more.”</p> <p><strong>Pizza</strong></p> <p>Whether it’s the stringy salty mozzarella cheese, the fluffy dough or the sugar in the tomato sauce, pizza ranks first in food addiction, according to a recent University of Michigan study.</p> <p>That’s because when you eat it, your blood sugar zips up quickly and then when it drops, you feel hungry again and want more.</p> <p><em>Image credits: Getty Images </em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/the-most-addicting-foods-on-the-planet" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

10 ways to upcycle old clothes

<h2>What is upcycling?</h2> <p>Upcycling, also known as ‘creative reuse,’ refers to the method of repurposing a used item into something else. In the context of upcycling clothes, it means taking an old piece of clothing that’s tattered, worn, broken, ripped or frayed and giving it new life so it can be worn or used again.</p> <p>“If you’ve heard the phrase ‘turning trash into treasure,’ that’s exactly what upcycling is,” explains Laura Wittig, CEO and founder of sustainable online platform Brightly. “Essentially, upcycling means taking something old – that would likely be destined for the landfill – and turning it into something new.”</p> <h2>What are the benefits of upcycling?</h2> <p>When you upcycle just about anything, you’re prolonging the item’s life and ultimately preventing it from heading to the landfill – or, at least, extending its life prior to the landfill. You’re choosing to get more use out of the item before throwing it away.</p> <p>“Upcycling is one of the best things you can do for the planet,” Wittig says. “It gives a new life to something that would typically be thrown away, keeping waste out of landfills. Aside from reducing waste, it also minimises the use of new materials needed to produce new products, as well as reduces the carbon emissions from mass manufacturing.” This means you’re also reducing your carbon footprint.</p> <p>Reader’s Digest consulted Stephanie Moram, CEO and founder Good Girl Gone Green and host of the Green Junkie podcast. She adds: “Upcycling reduces landfill waste and textile waste, requires less energy than recycling, saves natural resources – and therefore reduces greenhouse gas emissions in the process – encourages creativity, encourages sustainability practices and [results in] one-of-a-kind products.” Talk about a win-win!</p> <p>There’s also an undeniable monetary benefit to upcycling. “When you need something, your go-to response is probably buying something new. It’s something we’re all so used to doing,” Wittig notes. “But upcycling what you already have not only reduces waste – it also saves you a lot of money.”</p> <h2>What types of clothing can you upcycle?</h2> <p>Just about any type of clothing can be upcycled, as long as you have a vision and a little bit of imagination.</p> <p>“Clothing is one of the easiest things to upcycle,” Wittig says. “You can turn old jeans into jean shorts, tote bags and household items like wall organisers. T-shirts can be transformed into produce bags, doormats and hanging planters. You can even upcycle old socks, turning them into cleaning rags, erasers for whiteboards and bean bags for outdoor activities. The options are truly endless.”</p> <p>Clothing that can be easily upcycled includes (but is not limited to):</p> <ul> <li>T-shirts</li> <li>Sweaters</li> <li>Denim</li> <li>Jackets</li> <li>Shoes</li> <li>Pants</li> <li>Dresses</li> <li>Skirts</li> <li>Socks</li> <li>Sweatshirts</li> </ul> <p>In fact, even something as occasion- and fabric-specific as wedding gowns can be upcycled. Just take it from Nadia Manjarrez, creative director and founder of Nadia Manjarrez Studio Bridal, who launched both her debut bridal collection and a unique upcycling program last season, to much anticipation. “We upcycle wedding gowns and turn them into another meaningful garment,” Manjarrez tells Reader’s Digest.</p> <p>And the demand is certainly there. Global search for ‘upcycle wedding dress ideas’ has increased by 33 per cent versus the year prior, and ‘upcycled wedding dress’ is even a popular search on Etsy as of late, turning up small-business vendors who transform gowns into handkerchiefs and other special mementos.</p> <p>Manjarrez’s clients have the option of then, post-wedding, returning their wedding garment so that it can be altered or reconstructed for another future occasion. The process – a transformation, really – takes place at the brand’s atelier in Culiacán, Mexico, and takes anywhere from six to eight weeks. Manjarrez and her all-female team consult with customers in person and/or via email and video to turn wedding gowns into the repurposed, upcycled garments of their clients’ dreams.</p> <p>Some brides who anticipate having children in the future may even opt to upcycle their wedding dress into a christening gown for their future child. How crafty (and special!) is that? Celebrities are even hopping on board the upcycled-wedding-dress bandwagon. Emma Watson made her first red-carpet appearance in years in October 2021 donning an upcycled wedding dress designed by Harris Reed.</p> <h2>What to look for in clothes to be upcycled?</h2> <p>Though just about any piece of clothing can be upcycled, some fabrics are easier to work with than others. “The easiest materials to upcycle include any sort of denim and cotton T-shirts, but you can also find plenty of ways to use sweaters, blouses – really anything in your closet,” Wittig says. “You just need to get creative!”</p> <p>However, you may not want to upcycle more valuable clothing. Instead, you might want to sell vintage or brand-name pieces on a secondhand marketplace like Poshmark, Mercari, ThredUp or even Etsy. Sure, these clothes can technically be upcycled, but you’ll likely find more value in simply reselling them if you just don’t want them anymore.</p> <p>That being said, there still is quite a market for upcycling designer clothes and accessories. Demand for luxury items repurposed as fun (cheaper) accessories, like designer bags turned into baseball caps or pins, has search for terms like ‘upcycling Louis Vuitton’ on the rise. And Etsy isn’t just a spot for reselling vintage items or clothing of value, either; the online platform is seeing an uptick in searches for upcycled items and has always been a destination for makers of upcycled items. Because if anyone can learn how to upcycle everything, it’s the people of Etsy. Dayna Isom Johnson, a trend expert at Etsy, told the Wall Street Journal, “On Etsy, you will find over 10,000 search results for recycled tie items that are made into pillows, mini skirts, capes, grief quilts and more.”</p> <p>As long as you have a vision, the opportunities really are endless. “When it comes to upcycling, it just really depends on what you want to create,” Moram adds. “Some fabrics are more durable than others. My favourites are natural fibres.”</p> <h2>What clothes can you not upcycle?</h2> <p>There are very few restrictions with upcycling clothes. What will be trickier to upcycle (and/or recycle), however, is anything with grand embellishments – think sequins, metallics or anything with a lot of beading or embroidery. If you put your mind to it, though, just about any piece of clothing, regardless of fabric, can be upcycled into something else.</p> <p>And what about items to recycle vs upcycle? If you’re trying to recycle clothes, it’s imperative that the fabric is dry and clean. An item’s various fixtures, such as buttons, zippers and other kinds of non-fabric closures, should also be removed before recycling clothes. Blended fabrics may also cause a recycling hiccup while going through the conveyor belt of recycling machines. For this reason, blended fabrics may lend themselves better to being upcycled rather than recycled.</p> <p>Recycled polyester can also pose challenges for recycling centres. Sure, we see clothing made of recycled polyester – most often derived from recycled PET water bottles – all the time. But contrary to popular belief, polyester can be recycled only so many times before it loses quality. For that reason, recycled polyester is better for upcycling than continued recycling.</p> <p>“When it comes to recycling fabrics, the best materials are natural fibres,” Moram adds. “Blended materials, like polyester and nylon, are harder to recycle.”</p> <h2>10 ways to upcycle clothing</h2> <p>OK, it’s time to get creative! And if you’re not all that crafty, don’t worry. As you’ll see below, you don’t need a ton of sewing know-how to pull off most of these easy upcycling projects.</p> <ol> <li><strong>Dye it</strong></li> </ol> <p>Whether it’s an old bridesmaid dress or a shirt with a stain on it, dye can give a once-worn item new life. “[It’s] such a great idea to dye clothing to hide those stains,” Moram says. “You can buy some fabric-safe dyes, or use scraps you have around the house, like onions or avocado skin and pits, instead.”</p> <ol start="2"> <li><strong>Patch it</strong></li> </ol> <p>You don’t have to be a whiz with a sewing machine to patch over holes or rips. Use a needle and thread (or a sewing machine) to attach a patch, or even try gluing it on. Manjarrez adds, “Sometimes patches are iron-on and don’t even need to be sewn, but I prefer to create patches from a similar fabric to make it look more intentional and not like you are covering a mistake.”</p> <ol start="3"> <li><strong>Embroider it</strong></li> </ol> <p>Everything from T-shirts to jeans can be embroidered. All you need is a needle and thread – and a little time to learn a new pastime. “Embroidering is such an easy way to upcycle a pair of jeans you no longer wear,” Wittig says. “You can even mend a hole with embroidery, giving the jeans a new look and saving them at the same time.”</p> <ol start="4"> <li><strong>Cut it</strong></li> </ol> <p>Avoid hearing “Where’s the flood?” every time you wear your too-short jeans. Instead, whip out the scissors and start fresh. “The simplest way would be to just cut [old jeans into] shorts – as short as you want them – and you are ready to go,” Moram explains. “If you don’t want the frayed look, you can use a needle and thread and hem them.” Old, too-short or out-of-style denim can also be easily cut (and/or hemmed) into a skirt.</p> <ol start="5"> <li><strong>Turn it into a quilt</strong></li> </ol> <p>Yes, like when Bella’s mum gifts her a blanket made of their old trip T-shirts in Breaking Dawn. According to Wittig, you’ll need about 15 shirts for a smaller, lap-size blanket and even more for something as big as a quilt.</p> <p>“Start by selecting old garments with fun colours or patterns that would look good together,” Manjarrez advises. “Then cut each one the size you want for the quilt. Stitch or sew the T-shirts together. Once it is all put together, stitch or sew the quilt’s border.”</p> <ol start="6"> <li><strong>Turn it into a tote</strong></li> </ol> <p>Stop getting single-use plastic bags (or even paper bags) at the grocery store, and instead, make your own eco-friendly tote bags. Moram suggests using an old sweater or T-shirt for this project. “You can use them as produce bags, grocery bags, shoe bags, shopping bags and anywhere you would use a traditional cotton bag,” she says.</p> <p>And totes are just the beginning. Manjarrez likes the idea of DIYing a makeup bag by sewing the fabric into a rectangle and simply adding a button.</p> <ol start="7"> <li><strong>Turn it into a scrunchie</strong></li> </ol> <p>“What a fun project to do with your kids,” Moram says. “It could be as simple as cutting your fabrics from an old T-shirt to use as a hair ribbon or stitching together a piece of cloth to make a hair tie (without an elastic).” You can even tie-dye it!</p> <p>You can also transform old fabric into another gym accessory. “You can turn [an old tee] into sweat bandanas to keep sweat out of your face when working out,” Manjarrez adds.</p> <ol start="8"> <li><strong>Give it to the dog</strong></li> </ol> <p>You can turn old fabric into anything from a pet bed or blanket to even a toy or pet-sized T-shirt – and your pet will love that it smells like you. “For small dogs and cats, use an old pillowcase to make a bed,” Moram recommends. “Take old clothing and cut it into strips and fill the pillowcase with it. Stitch with a needle and thread, or sew the opening of the pillowcase.” Here’s one tutorial that doesn’t even require a sewing machine, just some creating tying.</p> <ol start="9"> <li><strong>Use it to clean your house</strong></li> </ol> <p>Old baby onesies? A long-sleeved shirt that no longer fits or is stained beyond recognition? All that and more make excellent cleaning cloths. “If your clothing is too worn out to upcycle, don’t toss it out,” Wittig urges. “Instead, cut it into squares to use as reusable cleaning cloths around the house. Once they’re all dirty, simply run them through the wash and keep them in a bin under the sink.”</p> <ol start="10"> <li><strong>Transform it into gift wrap</strong></li> </ol> <p>Instead of wasting money on single-use wrapping paper, ‘gift wrap’ presents using fabric-wrapping techniques. “Fold the fabric over the gift, gather the fabric edges, and pull upward,” Moram says. “Knot the fabric tails. So simple!”</p> <h2>Upcycling is a win-win</h2> <p>See? Upcycling isn’t nearly as complicated as it’s sometimes made out to be. With a little bit of glue, (maybe) a needle and thread, and some innovation, you can keep just about any clothing item from wasting away in the landfill by extending its life. After all, doing something as actionable as upcycling your clothes instead of throwing them out is a truly meaningful way to help the planet and even stave off any climate anxiety you may be experiencing about the current climate crisis.</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/diy-projects/10-ways-to-upcycle-old-clothes" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>

All-electric homes are better for your hip pocket and the planet. Here’s how governments can help us get off gas

<p><a href="https://theconversation.com/profiles/esther-suckling-1220357">Esther Suckling</a>, <em><a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a></em></p> <p>If every Australian household that uses gas went all-electric today, we would “save” more than 30 million tonnes of carbon dioxide emissions over the next ten years. That’s because there are more than <a href="https://www.energynetworks.com.au/resources/fact-sheets/reliable-and-clean-gas-for-australian-homes-2/">5 million households</a> on the gas network, and the <a href="https://grattan.edu.au/report/getting-off-gas">avoided emissions per home</a> ranges from 5-25 tonnes over the coming decade, depending on the location.</p> <p>Most people would spend less money on energy too. Electric appliances use less energy than gas appliances to do the same job, making them cheaper to run.</p> <p>Our <a href="https://grattan.edu.au/report/getting-off-gas">new report</a> shows how much most households can save by switching from gas to electricity for heating, hot water and cooking. The extra cash couldn’t come at a better time: about <a href="https://www.rmit.edu.au/news/all-news/2023/may/hidden-energy-poverty">a quarter of Australian households</a> say they found it difficult to pay their energy bills this year.</p> <p>But many households face hurdles that stop them, or make it hard for them, to go all-electric.

It’s a flat $3,890 figure for Brisbane, rather than a range, because there’s no gas heating.</span> <span class="attribution"><span class="source">Grattan Institute</span>, <span class="license">Author provided</span></span></figcaption></figure> <p>Households in Melbourne tend to use more gas than those in other mainland capitals, mainly because the winter is so cold. Our report found Melburnians who replace broken gas appliances with electric ones, or move into an all-electric home, could save up to A$13,900 over ten years. Households with rooftop solar will save even more.</p> <p>It’s a similar story in most parts of Australia except the west, where gas is relatively cheap. This mainly reflects differences in the historical development of the gas markets between the west and east coasts.</p> <p>Getting off gas could also be <a href="https://www1.racgp.org.au/ajgp/2022/december/health-risks-from-indoor-gas-appliances">good for your health</a>. Several studies link cooking with gas to <a href="https://www.nationalasthma.org.au/living-with-asthma/resources/patients-carers/factsheets/gas-stoves-and-asthma-in-children">childhood asthma</a>.</p> <p> </p> <h2>Households face a series of hurdles</h2> <p>Renters make up nearly a third of all households, and they have little or no control over the appliances that are installed. As most electric appliances cost more to buy than gas ones – and the subsequent bill savings flow to tenants – landlords have little incentive to upgrade their properties from gas to all-electric.</p> <p>Apartment living can increase the level of complexity. Multi-unit dwellings often bundle gas bills into body-corporate fees, limiting the occupants’ incentive to go all-electric. There can also be space constraints in these buildings. Centralised electric heat pumps, for example, take up more space than centralised gas water heaters.</p> <p>Then there are households that simply can’t afford the upgrade. Induction stoves and heat pumps are more expensive than their gas equivalents, by up to a combined $2,000. This initial outlay will soon be recovered by cheaper energy bills, but that doesn’t help households that don’t have the cash up front. The <a href="https://melbourneinstitute.unimelb.edu.au/data/taking-the-pulse-of-the-nation-2022/2023/energy-poverty">12% of households that skipped meals</a> to pay their energy bills in the past year are the most likely to remain locked into high gas bills.</p> <p>Some people also simply prefer cooking with gas. Some think induction cooktops will be no better than the poor-performing electric cooktops they may have used in the distant past. Others haven’t ever heard of a heat pump for hot water.</p> <h2>Here’s how governments can help</h2> <p>Governments, both state and federal, should lower the hurdles on the path to all-electric homes -– to reduce people’s cost of living and to cut carbon emissions.</p> <p>As a first step, state governments should ban new gas connections to homes. In 2021, more than 70,000 households joined the gas network. Trying to shift households off gas while allowing new connections is like pouring water into a bucket with a hole.</p> <p>Then, governments should provide landlords with tax write-offs on new induction stoves and heat pumps for hot water, for a limited time. After that, they should require every rental property to be all-electric. Governments should pay to upgrade public housing to all-electric, where they are the landlords. And they should pay not-for-profits managing community housing to do the same.</p> <p>The federal government should help all households to spread the cost of electric appliances over time. It should subsidise banks to offer low-interest loans for home electrification, via the Clean Energy Finance Corporation.</p> <p>And governments should set out to change people’s preferences, from gas to electric. They should embark on a multi-decade communication campaign, not unlike the campaign to upgrade from analogue to digital television in the early 2000s.</p> <p>A key challenge will be shifting people’s ideas about the best way to cook. There are precedents. In Gininderry, a new all-electric suburb of Canberra, one developer recruited chefs to run demonstrations on induction cooktops at the display village. The proportion of potential homebuyers <a href="https://ginninderry.com/wp-content/uploads/2021/08/Ginninderry-2017-Householder-Attitudes-to-Residential-Renewable-Energy-Futures.pdf">willing to consider buying an all-electric home</a> rose from 67% to 88%.</p> <figure><iframe src="https://www.youtube.com/embed/K9ytSh5TM9M?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Induction cooking with Chef David Wei at Ginninderry.</span></figcaption></figure> <h2>‘Green gas’ is no panacea: electricity is cheaper</h2> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=572&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=572&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=572&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=719&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=719&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/532117/original/file-20230615-23-n0wdqe.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=719&amp;fit=crop&amp;dpr=3 2262w" alt="Chart comparing the cost of hydrogen to electricity over time, showing hydrogen is more expensive and will remain so for decades" /></a><figcaption><span class="caption">Hydrogen is more expensive than electricity and will remain so for decades.</span> <span class="attribution"><span class="source">Grattan Institute</span>, <span class="license">Author provided</span></span></figcaption></figure> <p>The gas industry has another solution in mind: instead of switching from gas to electricity, it suggests using “green gas” -– biomethane or “green” hydrogen.

Green hydrogen is made by using electricity to split water into hydrogen and oxygen.</p> <p>But both options are <a href="https://theconversation.com/hydrogen-where-is-low-carbon-fuel-most-useful-for-decarbonisation-147696">too expensive and too far away</a>. Under the most generous of assumptions, green hydrogen will only become cost-competitive with electricity after 2045. And there is not enough biomethane commercially available to replace gas in households.</p> <p>Meanwhile, more than three million Australian homes already run on electricity alone.</p> <p>Getting the five million homes that use gas to the same point won’t be easy.

3 budget-friendly overseas holidays destinations

<p>You don’t have to rob a bank to go on an overseas trip. While you may be pinching pennies for retirement that doesn’t mean that a holiday is out of the question.</p> <p>Jetting off somewhere doesn’t have bleed you dry, actually, there are quite a few spectacular, great-value overseas destinations that allow you stretch your purse strings without making a dent in your savings. Why not consider one of these:</p> <p><strong>Northern Ireland</strong></p> <p>With many affordable guesthouses near Antrim’s seaside Giant’s Causeway and budget flight options, there are many great deals for a holiday in Northern Ireland. Make sure you see Pritzker-winning architect Zaha Hadid's cutting-edge Titanic Belfast museum, which brings fresh life to the dockyard where the doomed cruise liner was built.</p> <p>You’ll also want to make sure you take in the astounding interlocking rock columns of Antrim.</p> <p><strong>India</strong></p> <p>If you travel outside of the tourist favoruties – Mumabi and Delhi – there are many hotels that are reasonably priced if not utterly cheap. And the country has lots of landscape and culture for the buck. If you travel around by train and dine at low-key local places it will not only make you trip more authentic, but your pennies will go further.</p> <p>From lounging on the beaches of Goa to affordable skiing on Himachal Pradesh, there are many budget-friendly options including staying at Rajasthan's former palaces and living like a maharaja for less.</p> <p><strong>Laos</strong></p> <p>With better deals than Thailand, with its natural beauty and friendly locals, Laos is somewhat a majestic destination. With its sleepy riverfront and statue-decorated Buddha Park, Vientiane – the capital of Laos – offers much to be explored that you don’t have to pay for.</p> <p>Observe saffron-robed monks at dawn moving gracefully around the temple-filled holy town of Luang Prabang, or discover dramatic megalithic stone vessels, believed to be funerary urns, in the Plain of Jars.</p> <p><em>Image credits: Getty Images</em></p>

7 ways to make sure your garden is eco-friendly

<p>Your garden may be green but is it as environmentally friendly as it could be? Any green thumb knows gardening is about cultivation and conservation so ensuring your garden is eco-friendly will not only help your plot of paradise thrive but the wider environment as well. No matter how big or small your garden, here are 7 easy ways to make your garden greener.</p> <p><strong>Make your own compost</strong></p> <p>Don’t use chemic fertilisers when composting is the best way to give your plants added nutrients. Start a compost bin and you’ll not only feel better throwing out your dinner scraps but your garden will thrive.  </p> <p><strong>Reduce water usage</strong></p> <p>Adopting a few smart watering techniques will easily reduce precious water usage. Adding mulch to your garden will help hold moisture in the soil for longer which means less watering. Install a drip line as they require half the water used by sprinklers.</p> <p><strong>Don’t use pesticides</strong></p> <p>Most of the insects in your garden are beneficial so using a pesticide to kill the minority of pesky bugs will do more harm than good. If your garden does have pests, use an organic pesticide or one targeting that particular pest.</p> <p><strong>Recycle</strong></p> <p>Recycle your old pots or buy recycled items. Everyday items like plastic cartons and yoghurt pots can be used as seed trays.</p> <p><strong>Go native</strong></p> <p>Plants indigenous to Australia or from areas with similar climates (like Mediterranean plants) not only have a natural defence against pests but flourish in our weather conditions. They are easier to grow, use less water and require less maintenance.</p> <p><strong>Use rainwater</strong></p> <p>Why pay for water when you can get it for free? Use a rain barrel or any type of container to catch the rain. Make sure you place a screen over the barrel to keep out any debris.</p> <p><strong>Companion plant</strong></p> <p>Many first-time gardeners tend to randomly choose plants for their garden without considering which plants work well together. Known as companion planting, choosing plants that complement each other will help all your plants thrive and fend of pests.</p> <p><em>Image credits: Getty Images </em></p>

Who wants to be a billionaire? Thankfully for the planet, most people don’t

<p>Reality check: most people don’t actually want to be billionaires.</p> <p>A <a href="https://dx.doi.org/10.1038/s41893-022-00902-y" target="_blank" rel="noreferrer noopener">new study</a> is challenging the long-held economic belief that it’s in human nature to have unlimited wants, finding this widely held assumption only applies to a minority of people.</p> <p>In a survey of nearly 8,000 people from 33 countries across six continents, social psychologists asked people how much money they wanted to accrue in their “absolutely ideal life”.</p> <p>They found that in 86% of countries most people thought they could achieve the ideal life with US$10 million (AUD$14.3 million) or less, and in some countries the ideal was as little as US$1 million (AUD$1.4 million), across their entire lives.</p> <p>To put that into context, the current richest person in the world, Elon Musk, has a net worth of more than US$200 billion – that’s enough for 200,000 people to achieve their perceived ideal lives.</p> <p>The push to continually increase individual wealth and pursue unending economic growth has had dire environmental consequences for the planet, with resource use and <a href="https://cosmosmagazine.com/earth/earth-sciences/global-pollution-mapped-for-good-and-bad/" target="_blank" rel="noreferrer noopener">pollution</a> increasing alongside wealth.</p> <p>But these findings, published in <em>Nature Sustainability</em>, challenge the idea that approaches relying on limiting wealth and growth to achieve sustainability are against human ideals and aspirations.</p> <p>“The findings are a stark reminder that the majority view is not necessarily reflected in policies that allow the accumulation of excessive amounts of wealth by a small number of individuals,” explains co-author Dr Renata Bongiorno, a social psychologist at the University of Exeter and Bath Spa University in the UK.</p> <p>“If most people are striving for wealth that is limited, policies that support people’s more limited wants, such as a wealth tax to fund sustainability initiatives, might be more popular than is often portrayed.”</p> <h2>Would you want to win a billion in the lottery?</h2> <p>The researchers specifically asked people to imagine their absolutely ideal life, and then consider how much money would want in that life.</p> <p>Participants made a choice of their preferred prize in a hypothetical lottery, choosing from US$10,000, US$100,000, US$1 million, US$10 million, US$100 million, US$1 billion, US$10 billion or US$100 billion.</p> <p>It was emphasised that the odds of winning each lottery were identical.</p> <p>The researchers hypothesised that people with insatiable wants – those who cannot conceive of a point where their wants would be fully satiated, so they will always aspire to accumulate more/better goods – would choose the maximum of US$100 billion over all the lesser (limited) amounts.</p> <p>But while people with unlimited wants were identified in every country surveyed, they were always in the minority. They tended to be younger people and city-dwellers, who placed more value on success, power and independence.</p> <p>They were also more common in countries with greater acceptance of inequality, and in countries that are more collectivistic – that focus more on group than individual responsibilities and outcomes. </p> <p>“The ideology of unlimited wants, when portrayed as human nature, can create social pressure for people to buy more than they actually want,” says lead researcher Dr Paul Bain, from the Department of Psychology at the University of Bath, UK.</p> <p>“Discovering that most people’s ideal lives are actually quite moderate could make it socially easier for people to behave in ways that are more aligned with what makes them genuinely happy and to support stronger policies to help safeguard the planet.”</p> <p><em>Image credits: Getty Images</em></p> <p><em><!-- Start of tracking content syndication.

Astronomers have detected another ‘planet killer’ asteroid. Could we miss one coming our way?

<p>If you surfed the web this morning, you may have seen news of the latest existential threat to humanity: a “planet killer” asteroid named 2022 AP7.</p> <p>Luckily for us 2022 AP7 “has no chance to hit the Earth currently”, <a href="https://www.theguardian.com/science/2022/nov/01/huge-planet-killer-asteroid-discovered-and-its-heading-our-way">according</a> to Scott Sheppard at the Carnegie Institution for Science. He and his international team of colleagues <a href="https://iopscience.iop.org/article/10.3847/1538-3881/ac8cff/pdf">observed 2022 AP7</a> in a trio of “rather large” asteroids obscured by the Sun’s glare (the other two don’t pose a risk).</p> <p>2022 AP7 orbits the Sun every five years, and currently crosses Earth’s orbit when Earth is on the other side of the Sun to it. Eventually its movement will sync with Earth’s and it will cross much closer by, but this will be centuries into the future.</p> <p>We simply don’t know enough about 2022 AP7 to precisely predict the danger it may pose centuries from now. At the same time, we suspect there could be other “planet killers” out there yet to be discovered. But how many? And what’s being done to find them?</p> <p><strong>What makes a planet killer?</strong></p> <p>Asteroid 2022 AP7 is the largest potentially hazardous asteroid (PHA) found in eight years, with a diameter between 1.1km and 2.3km. For context, an asteroid with a diameter more than 1km is enough to trigger a <a href="https://en.wikipedia.org/wiki/Cretaceous%E2%80%93Paleogene_extinction_event">mass extinction event</a> on Earth.</p> <p>As well as having a diameter greater than 1km, an asteroid also needs to have an orbit that crosses Earth’s to be considered potentially dangerous. In the case of 2022 AP7, any threat is centuries down the track. The important point is it has been detected and can now be tracked. This is the best possible outcome.</p> <p>It is estimated we’ve already <a href="https://theconversation.com/in-a-world-first-nasas-dart-mission-is-about-to-smash-into-an-asteroid-what-will-we-learn-189391">discovered</a> about 95% of potentially hazardous asteroids, and that there are fewer than 1,000 of these. The work of Sheppard and colleagues highlights that hunting down the remaining 5% – some 50 asteroids – will be a massive effort.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/492923/original/file-20221102-25180-74aqvo.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/492923/original/file-20221102-25180-74aqvo.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=304&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/492923/original/file-20221102-25180-74aqvo.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=304&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/492923/original/file-20221102-25180-74aqvo.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=304&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/492923/original/file-20221102-25180-74aqvo.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=382&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/492923/original/file-20221102-25180-74aqvo.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=382&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/492923/original/file-20221102-25180-74aqvo.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=382&amp;fit=crop&amp;dpr=3 2262w" alt="" /><figcaption><span class="caption">Statistically, there’s less of a chance of a larger asteroid colliding with Earth compared to a smaller one.</span> <span class="attribution"><span class="source">NASA</span></span></figcaption></figure> <p><strong>What constitutes a near miss?</strong></p> <p>NASA <a href="https://www.jpl.nasa.gov/asteroid-watch">closely tracks</a> all known objects in the Solar System. But every now and again an object will catch us off guard.</p> <p>In 2021, we had a close call with an asteroid called <a href="https://en.wikipedia.org/wiki/2021_UA1">2021 UA1</a>. It came only a few thousand kilometres from Earth, over the Antarctic. In cosmic terms, this is uncomfortably close. However, 2021 UA1 was only two metres across, and therefore posed no substantial risk.</p> <p>There are likely hundreds of millions of objects of this size in our Solar System, and it’s not uncommon for them to impact Earth. In these cases, most of the object burns up in the atmosphere and creates a spectacular light show, with little risk to life.</p> <p>In 2019 another <a href="https://theconversation.com/an-asteroid-just-buzzed-past-earth-and-we-barely-noticed-in-time-120972">asteroid</a> with a 100m diameter passed Earth some 70,000km away. It was publicly announced mere hours before it flew past. While it wasn’t as close, it was of a much more concerning size.</p> <p>These near misses reiterate how important it is for us to speed up the search for near-Earth objects.</p> <p><strong>Blind spots</strong></p> <p>The reason we haven’t already found every object that could one day pass nearby Earth is largely because of observational blind spots, and the fact we can’t observe all parts of the sky all the time.</p> <p>To find 2022 AP7, Sheppard and colleagues used a telescope at twilight soon after the Sun had set. They had to do this because they were looking for asteroids in the vicinity of Venus and Earth. Venus is currently on the <a href="https://theskylive.com/where-is-venus">other side of the Sun</a> to Earth.</p> <p>Making observations close to the Sun is difficult. The Sun’s glare overwhelms the weak light reflected off small asteroids – presenting a blind spot. But just before and after sunset, there’s a small window in which the Sun’s glare no longer blocks the view.</p> <p>Right now there are only about 25 asteroids known to have well-determined orbits that lie entirely within Earth’s orbit.

Pubs and clubs – your friendly neighbourhood money-laundering service, thanks to 86,640 pokies

<p>Billions of dollars in proceeds of crime are being funnelled through clubs and pubs in New South Wales, <a href="https://www.crimecommission.nsw.gov.au/final-islington-report.pdf" target="_blank" rel="noopener">according to</a> the NSW Crime Commission. Predictably, the industry is claiming it’s not an issue and solutions are too difficult.</p> <p>Laundering money through a local club or hotel involves loading cash into one of the state’s <a href="https://www.liquorandgaming.nsw.gov.au/resources/gaming-machine-data" target="_blank" rel="noopener">86,640 poker machines</a>, then cashing out and claiming the money as winnings.</p> <p>This is not a preferred method for most organised criminals, the crime commission says. Sophisticated criminals have other methods. But it is still a sizeable proportion of the estimated $20 billion in criminal proceeds laundered in NSW each year.</p> <p>In Queensland, you can put only $100 into a poker machine at one time. In Victoria the limit is $1,000. In NSW, newer machines allow $5,000, and older machines up to <a href="https://www.theguardian.com/australia-news/2022/jul/14/nsw-poker-machine-laws-may-increase-risk-of-money-laundering-says-commission" target="_blank" rel="noopener">$10,000</a>. For supposedly harmless suburban fun it’s hard to understand why such sums are allowed.</p> <p>The findings of the NSW Crime Commission’s <a href="https://www.crimecommission.nsw.gov.au/final-islington-report.pdf" target="_blank" rel="noopener">inquiry into money laundering via clubs and hotels</a> follow scandalous money-laundering revelations from casino inquiries in <a href="https://theconversation.com/not-suitable-where-to-now-for-james-packer-and-crowns-other-casinos-154938" target="_blank" rel="noopener">NSW</a>, <a href="https://theconversation.com/illegal-dishonest-unethical-and-exploitative-but-crown-resorts-keeps-its-melbourne-casino-licence-170625" target="_blank" rel="noopener">Victoria</a>, Western Australia and Queensland.</p> <p>Those inquiries found Crown Resorts and Star Entertainment allowed hundreds of millions of dollars to pass through their casinos, in contravention of anti-money-laundering regulations.</p> <p>Both companies were found not fit to hold their licences. Crown has been fined <a href="https://www.abc.net.au/news/2022-05-30/crown-casino-fined-80-million-dollars-china-union-pay/101111660" target="_blank" rel="noopener">$80 million</a> in Victoria. Star has been fined <a href="https://www.abc.net.au/news/2022-10-16/star-casino-set-to-be-fined-100-million/101541354" target="_blank" rel="noopener">$100 million</a> in NSW, and had its licence suspended.</p> <p>Both have been required to undergo extensive “renewal”. They have agreed to adopt cashless gaming to better protect against money laundering.</p> <p>It’s therefore unsurprising the NSW Crime Commission’s principal recommendation is to introduce a cashless system for all electronic gaming machines in NSW. Also unsurprising is that the industry is focused on why it shouldn’t.</p> <h2>Cashless gambling recommended</h2> <p>The NSW Crime Commission’s report recommends a cashless gambling system for pubs and clubs the same as for casinos – consistent with the identification requirements of Australia’s <a href="https://www.legislation.gov.au/Details/C2021C00243" target="_blank" rel="noopener">Anti-Money Laundering and Counter-Terrorism Financing Act</a>.</p> <p>Electronic gaming cards would record amounts loaded and withdrawn, times, turnover, and losses/wins. The maximum amount of cash able to be loaded on to a player’s account in a single day would be $1,000.</p> <p>Josh Landis, the chief executive of ClubsNSW (which represents most of the state’s 1,200 licensed clubs) <a href="https://www.abc.net.au/sydney/programs/breakfast/breakfast/14090002" target="_blank" rel="noopener">has said</a> that such technology has not been trialled, and was uncosted and unproven.</p> <p>But Crown Resorts and Star Entertainment are implementing such systems. Similar systems have been operating successfully in Norway <a href="https://nla.gov.au/nla.obj-571970219/view" target="_blank" rel="noopener">since 2009</a>, and in Sweden <a href="https://aifs.gov.au/resources/policy-and-practice-papers/pre-commitment-systems-electronic-gambling-machines" target="_blank" rel="noopener">since 2013</a>.</p> <p>Victoria has already implemented a card-based <a href="https://www.yourplay.com.au/" target="_blank" rel="noopener">precommitment system</a>, incorporating most necessary characteristics. Every poker machine in the state is linked to this system. Its flaw is that it is voluntary, allowing those who wish to clean dirty money, or avoid a limit, <a href="https://www.justice.vic.gov.au/safer-communities/gambling/evaluation-of-yourplay-final-report" target="_blank" rel="noopener">to simply opt out</a>.</p> <h2>It’s not just about money laundering</h2> <p>Money laundering isn’t the only reason to introduce cashless gaming systems.</p> <p>On any day in NSW, <a href="https://www.responsiblegambling.nsw.gov.au/__data/assets/pdf_file/0008/881279/NSW-Gambling-Survey-2019-report-FINAL-AMENDED-Mar-2020.pdf" target="_blank" rel="noopener">hundreds of thousands of people</a> are experiencing significant gambling harm, mostly using poker machines. Many hundreds of thousands more – <a href="https://www.tandfonline.com/doi/abs/10.1080/14459795.2017.1331252" target="_blank" rel="noopener">partners, children, employers</a> – are also harmed as a consequence.</p> <p>A pre-commitment system incorporating all the features of the NSW Crime Commission’s cashless model would stop money laundering and also help those struggling to control their gambling. For those who want to stop it would provide a truly effective gambling self-exclusion system.</p> <p>The Tasmanian government <a href="https://www.abc.net.au/news/2022-09-16/tasmania-pokies-gambling-limits-reform-explained/101446788" target="_blank" rel="noopener">has promised to implement</a> a statewide system by 2024.</p> <h2>A matter of political commitment</h2> <p>The real test here isn’t technology. It’s political will.</p> <p>NSW Premier Dominic Perrottet has expressed concern at the <a href="https://www.smh.com.au/politics/nsw/premier-says-pokies-taxing-on-the-misery-of-others-vows-to-do-better-20221002-p5bmjz.html" target="_blank" rel="noopener">exploitation of vulnerable people</a> via gambling.

According to an <a href="https://www.abc.net.au/news/2021-11-23/how-gambling-industrys-biggest-political-donors-influence-votes/100592068" target="_blank" rel="noopener">ABC investigation</a>, they have doled out about a third of $40 million in political donations disclosed by gambling-related organisations over the past two decades.</p> <p>Since 2010, ClubsNSW has signed <a href="https://www.smh.com.au/national/nsw/the-million-dollar-men-who-run-the-clubs-industry-20221011-p5bowp.html" target="_blank" rel="noopener">memorandums of understanding</a> with incoming governments to protect its members interests.</p> <p>In the first six months of 2022 (the <a href="https://nswgov.sharepoint.com/sites/GamingMachineReports/Shared%20Documents/Forms/AllItems.aspx" target="_blank" rel="noopener">most recent data</a> available), people in NSW lost $4 billion using pokies – $2.4 billion in clubs, $1.6 billion in pubs. This is 23% more than the same period in 2019, before pandemic restrictions.</p> <p>Yet according to the Australian Hotels Association, the industry is on “<a href="https://www.afr.com/chanticleer/why-a-pokie-crackdown-will-have-pub-owners-nervous-20221026-p5bt48" target="_blank" rel="noopener">on its knees</a>” and being told to introduce “an unproven, untested, un-costed and unnecessary cashless system”.</p> <p>In NSW, gambling operators are not permitted to donate to state political campaigns.

Coffin? Casket? Cremation? How to make your death more environmentally friendly

<p>We can all agree humans need to reduce their impact on the environment. And while most of us think of this in terms of daily activities – such as eating less meat, or being water-wise – this responsibility actually extends beyond life and into death.</p> <p>The global population is closing on <a href="https://www.un.org/en/un-chronicle/global-population-will-soon-reach-8-billion-then-what" target="_blank" rel="noopener">eight billion</a>, and the amount of land available for human burial is <a href="https://www.sciencefocus.com/the-human-body/deal-with-the-dead/" target="_blank" rel="noopener">running out</a>, especially in small and densely populated countries.</p> <p>To minimise environmental impact, human bodies should return to nature as quickly as possible. But the rate of decay in some of the most common traditional disposal methods is very slow. It can take <a href="https://www.businessinsider.com/how-long-it-takes-human-body-decompose-grave-coffin-2019-8" target="_blank" rel="noopener">several decades</a> for a body to decompose.</p> <p>In a one-of-its-kind study, our team analysed <a href="https://irispublishers.com/gjfsm/fulltext/a-taphonomic-examination-of-inhumed-and-entombed-remains-in-parma-cemeteries-italy.ID.000518.php" target="_blank" rel="noopener">408 human bodies</a> exhumed from grave pits and stone tombs in the north of Italy to find out what conditions help speed up decay.</p> <h2>The environmental cost of traditional burials</h2> <p>Funeral rituals should respect the dead, bring closure to families and promote the reaching of the afterlife in accordance with people’s beliefs. This looks different for different people. Although the Catholic church has allowed cremation <a href="https://www.nytimes.com/2016/10/26/world/europe/vatican-bans-scattering-of-human-ashes.html" target="_blank" rel="noopener">since 1963</a>, it still prefers burials. Muslims are always supposed to be buried, while most Hindus are cremated.</p> <p>In Australia, however, the latest census revealed almost 40% of the population identifies as “<a href="https://theconversation.com/no-religion-is-australias-second-largest-religious-group-and-its-having-a-profound-effect-on-our-laws-185697" target="_blank" rel="noopener">not religious</a>”. This opens up more avenues for how people’s bodies may be handled after death.</p> <p>Most traditional burial practices in industrialised countries have several long-lasting harmful <a href="https://apps.who.int/iris/bitstream/handle/10665/108132/EUR_ICP_EHNA_01_04_01%28A%29.pdf" target="_blank" rel="noopener">effects</a> on the environment. Wood and metal fragments in coffins and caskets remain in the ground, leaching harmful chemicals through paint, preservatives and alloys. Chemicals used for embalming also remain in the ground and can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3315260/" target="_blank" rel="noopener">contaminate</a> soil and waterways.</p> <p>Cremation also has a large <a href="https://www.nationalgeographic.com/science/article/is-cremation-environmentally-friendly-heres-the-science" target="_blank" rel="noopener">carbon footprint</a>. It requires lots of trees for fuel and produces millions of tons of carbon dioxide each year, as well as toxic volatile compounds.</p> <p>There are several alternatives to traditional burials. These include “water cremation” or “resomation” (where the body is rapidly dissolved), human <a href="https://www.abc.net.au/news/2021-09-26/body-composting-a-green-alternative-to-burial-cremation/100486964" target="_blank" rel="noopener">composting</a>, mummification, cryonics (freezing and storage), <a href="https://eirene.ca/blog/space-burial-ashes-in-orbit" target="_blank" rel="noopener">space burials</a>, and even turning the body into <a href="https://edition.cnn.com/2017/05/03/world/eco-solutions-capsula-mundi/index.html" target="_blank" rel="noopener">trees</a> or the ashes into <a href="https://www.nationalgeographic.com/magazine/article/ashes-to-diamonds-reefs-rockets-how-we-will-memorialize-dead" target="_blank" rel="noopener">diamonds</a> or <a href="https://www.andvinyly.com/" target="_blank" rel="noopener">record vinyls</a>.</p> <p>However, many of these alternatives are either illegal, unavailable, costly or not aligned with people’s beliefs. The vast majority choose coffin burials, and all countries accept this method. So the question of sustainable burials comes down to choosing between the many types of <a href="https://australian.museum/about/history/exhibitions/death-the-last-taboo/burial-coffins-and-caskets/?gclid=CjwKCAjwx7GYBhB7EiwA0d8oe-mOKjLns2Gj5mpj-mu_kskmPPCKjhOqUrUAEjC05D4pnSXyBP3xrhoCE9oQAvD_BwE" target="_blank" rel="noopener">coffins available</a>.</p> <h2>What leads to faster decomposition?</h2> <p>Coffins range from traditional wooden caskets, to cardboard coffins, to natural coffins made from willow, banana leaf or bamboo, which decompose faster.</p> <p>The most environmentally sustainable choice is one that allows the body to decompose and reduce to a skeleton (or “skeletonise”) quickly – possibly in just a few years.</p> <p>Our research has presented three key findings on conditions that promote the skeletonisation of human bodies.</p> <p>First, it has confirmed that bodies disposed in traditionally sealed tombs (where a coffin is placed inside a stone space) can take more than 40 years to skeletonise.</p> <p>In these sealed tombs, bacteria rapidly consume the oxygen in the stone space where the coffin is placed. This creates a micro-environment that promotes an almost indefinite preservation of the body.</p> <p>We also found burial grounds with a high percentage of sand and gravel in the soil promote the decomposition and skeletonisation of bodies in less than ten years – even if they are in a coffin.</p> <p>That’s because this soil composition allows more circulation of air and microfauna, and ample water drainage – all of which are helpful for degrading organic matter.</p> <p>Finally, our research confirmed previous suspicions about the slow decomposition of entombed bodies. We discovered placing bodies inside stone tombs, or covering them with a stone slab on the ground, helps with the formation of corpse wax (or “<a href="https://pubmed.ncbi.nlm.nih.gov/33596512/" target="_blank" rel="noopener">adipocere</a>”).</p> <p>This substance is the final result of several chemical reactions through which the body’s adipose (fat) tissues turn to a “soapy” substance that’s very resistant to further degradation. Having corpse wax slows down (if not completely arrests) the decomposition process.</p> <h2>A new, greener option</h2> <p>In looking for innovative burial solutions, we had the opportunity to experiment with a new type of body disposal in a tomb called an “<a href="https://www.mdpi.com/2673-6756/2/3/37" target="_blank" rel="noopener">aerated tomb</a>”.</p> <p>Over the past 20 years aerated tombs have been developed in some European countries including France, Spain and Italy (where they <a href="https://www.tecnofar-solutions.com/prodotti/sistema-aerato-loculi" target="_blank" rel="noopener">have</a> <a href="https://www.argema.net/loculi-aerati/" target="_blank" rel="noopener">been</a> <a href="https://www.ala-strutture-cimiteriali.com/loculi-aerati" target="_blank" rel="noopener">commercialised</a>). They allow plenty of ventilation, which in turn enables a more hygienic and faster decomposition of bodies compared to traditional tombs.</p> <p>They have a few notable features:</p> <ul> <li> <p>an activated carbon filter purifies gases</p> </li> <li> <p>fluids are absorbed by two distinct biodegrading biological powders, one placed at the bottom of the coffin and the other in a collecting tray beneath it</p> </li> <li> <p>once the body has decomposed, the skeletal remains can be moved to an ossuary (a site where skeletal remains are stored), while the tomb can be dismantled and most of its components potentially recycled.</p> </li> </ul> <p>Aerated tombs are also cheaper than ordinary tombs and can be built from existing tombs. They would be simple to use in Australia and would comply with public health and hygiene standards.</p> <p>Most of us don’t spend much time thinking about what will happen to our bodies after we die. Perhaps we should. In the end this may be one of our most important last decisions – the implications of which extend to our precious planet.</p> <p><strong>This article originally appeared on <a href="https://theconversation.com/coffin-casket-cremation-how-to-make-your-death-more-environmentally-friendly-188456" target="_blank" rel="noopener">The Conversation</a>.</strong></p> <p><em>Image: Shutterstock</em></p>

Cadbury's huge change in a bid to save the planet

<p>In a “world first” from Cadbury, the iconic chocolate block is about to change, in efforts to save the environment.</p> <p>Looking to curb their contribution of single-use plastic to landfill, Mondelez International, the company that owns the confectionary giant have unveiled a new and sustainable version of the signature purple packaging that is now 100% recyclable.</p> <p>The chocolate-maker said it used “emerging advanced recycling technology” to create soft plastic packaging that contains up to 30% recycled content, saving 120 tonnes of packaging waste from going to landfill.</p> <p>“Until recently, soft plastic packaging has been considered a single-use material,” Mondelēz International chief executive Dirk Van de Put said.</p> <p>“The development of advanced recycling technology and our significant investment in recycled soft plastic means it’s now possible for Cadbury fans to enjoy their favourite treats more sustainably here in Australia.”</p> <p>Australia is the first country to experience the new sustainable wrappers, which are initially launching on Cadbury Dairy Milk, Caramilk and Old Gold family blocks.</p> <p>The brand said it was “committed” to rolling out the eco-friendly packaging across the entire Cadbury range in the coming years, however in order to create the new eco-friendly packaging Cadbury sourced 120 tonnes of recycled content from overseas.</p> <p>Australia doesn't yet have the ability to recycle soft plastic into food-friendly packaging.</p> <p>The first Cadbury family blocks in their new packaging are being delivered to major retailers and supermarkets across Australia this week.</p> <p><em>Image: Woolworths</em></p>
