Invasive species may travel trade routes

<div> <div class="copy"> Invasive species could increase their global presence via China’s developing trade routes, researchers warn. A new study models the distribution and likelihood of invasion of terrestrial vertebrate species along China’s Belt and Road Initiative (<a rel="noopener" href="https://www.worldbank.org/en/topic/regional-integration/brief/belt-and-road-initiative" target="_blank">BRI</a>), a massive infrastructure development project involving six proposed economic corridors and 121 countries. The largest project of its kind ever attempted, the BRI has an estimated cost of an unprecedented US$4 trillion for road development, shipping routes and ports. A research team led by Yiming Li from the Chinese Academy of Sciences used species distribution modelling to assess the introduction risks for a suite of 816 known invasive terrestrial vertebrate species, as well as habitat suitability across the BRI regions. Habitat suitability is an indicator of the likelihood a species will become established after introduction. The findings, reported in a <a rel="noopener" href="https://www.cell.com/current-biology/fulltext/S0960-9822(18)31670-1" target="_blank">paper</a> published in the journal Current Biology, reveal that more than two thirds of BRI countries have a lethal combination of introduction risk and high habitat suitability. “Of particular concern, we find that the majority of both introduction hotspots and areas with high habitat suitability fall along the six proposed Economic Corridors,” says Li. The team identified 14 “invasion hotspots” where biosecurity efforts might best be directed. They are located across the BRI countries, from the Caribbean Islands, northern Africa and Eastern Europe to Southeast Asia and New Zealand. Australia is not a member country or signatory to the scheme. One of the 816 <a rel="noopener" href="http://www.iucngisd.org/gisd/100_worst.php" target="_blank">species of concern</a> is the large North American bullfrog, (Lithobates catesbeianus or Rana catesbeiana), which is originally from east of the Rocky Mountains. It is a voracious predator of local frogs and other reptiles, and a carrier of chytrid fungus, which decimates local frog populations. The bullfrog is now established in over 40 countries, and very <a rel="noopener" href="https://www.nationalgeographic.com/animals/2004/09/news-bullfrogs-invading-nearly-unstoppable/" target="_blank">difficult to eradicate</a> once established. The findings have prompted the researchers to urgently recommend “the initiation of a project targeting early prevention, strict surveillance, rapid response and effective control of alien species in BRI countries to ensure that this development is sustainable.” This proposed biosecurity plan and its implementation could be funded by the establishment of a dedicated fund, they suggest. In separate <a rel="noopener" href="https://dx.doi.org/10.1038/s41559-017-0452-8" target="_blank">correspondence</a> to the journal Nature Ecology and Evolution, Alex Lechner from the University of Nottingham Malaysia and two colleagues suggest that as the 50-year BRI is still only five years old, there is an opportunity to incorporate biodiversity conservation as one of its core values. For example, they suggest, the Chinese government could plan and implement a network of protected areas and wildlife corridors across Eurasia, as well as preventing and/or controlling alien species invasion effectively. China has embraced renewable energy and technology enthusiastically, and could potentially be a world leader in biodiversity conservation, they write.

COP26: New Zealand depends on robust new rules for global carbon trading to meets its climate pledge

As the <a href="https://ukcop26.org/">COP26</a> climate summit draws to a close, debate continues on one key issue in particular: a new rule book for global carbon trading to allow countries to purchase emissions reductions from overseas to count towards their own climate action. The world has generally welcomed headline-grabbing <a href="https://www.theguardian.com/environment/2021/nov/07/so-what-has-cop26-achieved-so-far">agreements</a> on halting deforestation and tackling methane and <a href="https://ukcop26.org/end-of-coal-in-sight-at-cop26/">coal</a>. Likewise ambitious commitments from some large polluters, most notably <a href="https://www.theguardian.com/environment/2021/nov/07/so-what-has-cop26-achieved-so-far">India’s pledge</a> to reach net zero carbon by 2070. But the devil is in the detail and there is serious concern that some of these commitments are only voluntary, while others look unachievable. Defining the rules for international carbon trading is a contentious agenda item — but one that will partly determine whether countries can meet their pledges and collectively limit global warming to <a href="https://www.theguardian.com/environment/2021/nov/05/president-of-paris-summit-says-18c-commitment-is-only-hypothetical">as close to 1.5℃ as possible</a>. The new rules, known as <a href="https://www.carbonbrief.org/in-depth-q-and-a-how-article-6-carbon-markets-could-make-or-break-the-paris-agreement">Article 6</a> under the <a href="https://unfccc.int/process-and-meetings/the-paris-agreement/the-paris-agreement">Paris Agreement</a>, will be important for New Zealand. During COP26, New Zealand announced its new Nationally Determined Contribution (<a href="https://unfccc.int/process-and-meetings/the-paris-agreement/nationally-determined-contributions-ndcs/nationally-determined-contributions-ndcs">NDC</a>) to reduce emissions by <a href="https://www.nzherald.co.nz/nz/politics/climate-change-conference-emissions-to-be-cut-by-50-per-cent-below-2005-levels-by-2030/WRDDTBYBIRDSOTQSDP7UH6KWLI/">50% on 2005 levels by 2030</a>. Prime Minister Jacinda Ardern described this as “our fair share” and it is indeed a significant step up on New Zealand’s previous pledge to cut emissions by 30%. It leaves the country with 571 Megatons of CO₂-equivalent emissions to “spend” between 2022 and 2030. <h2>New rules for global carbon trading</h2> The New Zealand government stated its “<a href="https://www.nzherald.co.nz/nz/politics/climate-change-conference-emissions-to-be-cut-by-50-per-cent-below-2005-levels-by-2030/WRDDTBYBIRDSOTQSDP7UH6KWLI/">first priority</a>” was to reduce domestic emissions, but it acknowledged that alone could not meet the country’s new pledge. In fact, two thirds of the promised emissions reductions will have to come through overseas arrangements, especially with nations in the Asia-Pacific region. The <a href="https://www.climatecommission.govt.nz/our-work/advice-to-government-topic/inaia-tonu-nei-a-low-emissions-future-for-aotearoa/test-summary/">Climate Change Commission</a> has been critical of this approach, describing it as “purchasing offshore mitigation, rather than [doing] what was necessary to achieve actual emissions reductions at source”. But the approach is allowed under the <a href="https://unfccc.int/process-and-meetings/the-paris-agreement/the-paris-agreement">Paris Agreement</a>, which all states at COP26 have signed up to. This would allow one country to buy credits from another country that has exceeded its NDC, or to carry out activities that reduce emissions in another (host) country and count those towards its own NDC. It also supports non-market approaches to climate cooperation between countries around technology transfer, finance and capacity building. But these provisions have proved contentious, not least because they could result in double counting of emissions reductions, unless clear and robust operational rules are agreed. The COP26 summit has made some progress on this, but many finer details are yet to be resolved. <h2>Cutting emissions at home versus elsewhere</h2> Uncertainty about carbon market rules will be particularly problematic for New Zealand, given its reliance on overseas activities to meet its new NDC. There are also practical questions around how much of these activities will count towards New Zealand’s NDC, and how ready potential partners in the Pacific are for such carbon market trading mechanisms. Pacific Island nations are not currently trading or part of established carbon markets. They may not be able to develop the necessary technical expertise to ensure fairness, compliance and transparency well in advance of 2030. While there is scope to pursue opportunities to reduce emissions beyond our shores, we should be looking harder at what can be done domestically to help fulfil our NDC in the short time available. Public <a href="https://consult.environment.govt.nz/climate/emissions-reduction-plan/">consultation</a> on the government’s first <a href="https://environment.govt.nz/publications/emissions-reduction-plan-discussion-document/">emissions reduction plan</a> is currently underway until November 24. A final version is due in May 2022 and is expected to set out strategies for specific sectors (transport, energy and industry, agriculture, waste and forestry) to meet emissions budgets. It will also include a multi-sector plan to adapt to climate change, and to mitigate the impacts emissions cuts may have on people. It’s not ideal that a concrete plan for domestic emissions reductions is still six months away. But this does provide opportunity for people and interest groups to help shape priorities and pathways, and to encourage the government to set bolder domestic targets than would otherwise have been likely. The Climate Change Commission has already produced <a href="https://www.climatecommission.govt.nz/our-work/reducing-emissions/">recommendations for a low-emissions Aotearoa</a>, including the rapid adoption of electric vehicles, reduction in animal stocking rates and changing land use towards forestry and horticulture. Now is also the time to start building capacity to support Pacific Island nations in designing their carbon market policies. New Zealand has already <a href="https://www.beehive.govt.nz/release/new-zealand-increases-climate-aid-contribution">pledged NZ$1.3 billion</a> in funding for climate change aid, about half of which will go to Pacific Island countries. Allocating some of this to enhancing technical know-how will help create a level playing field in carbon trading. It would ensure that whichever overseas arrangements materialise, these will be fair and deliver an “<a href="https://unfccc.int/sites/default/files/english_paris_agreement.pdf">overall mitigation in global emissions</a>”, as the Paris Agreement requires. <a href="https://theconversation.com/profiles/nathan-cooper-749971">Nathan Cooper</a>, Associate Professor of Law, <a href="https://theconversation.com/institutions/university-of-waikato-781">University of Waikato</a> and <a href="https://theconversation.com/profiles/kemi-hughes-1288573">Kemi Hughes</a>, Doctoral Researcher in Climate Change Governance, <a href="https://theconversation.com/institutions/university-of-waikato-781">University of Waikato</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Insider trading has become more subtle

Insider trading comes in two main forms: arguably legal and clearly illegal. But, as with drugs in sport, it’s hard to tell when arguably legal ends and clearly illegal begins. It is generally accepted that it is wrong to buy shares in the company you run when you know something about it that the market does not. It’s especially wrong to buy shares when you are telling the market that things are much worse for the company than you know them to be. Join 130,000 people who subscribe to free evidence-based news. Get newsletter But what about suddenly sharing everything – an avalanche of information – in the lead-up to a share purchase in order to muddy the waters and create enough uncertainty to lower the price? Chief executives have enormous discretion over the tone and timing of the news they release, generally answering to no one. A linguistic analysis of twelve years worth of news releases by 6764 US chief executives just published by myself and two University of Queensland colleagues in the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0378426620300881">Journal of Banking and Finance</a> suggests they are using this discretion strategically. Not clearly illegal (how can oversharing be illegal?) their behaviour can have the same effect as talking down their share price while buying, something that is clearly illegal. Spreads matter, as well as signs Earlier analyses of insider trading have looked at only the “sign” of the information released to to the share market. On balance was the tone of one month’s news releases positive or negative? We have looked at the “spread”, the range from positive to negative as well as the net result. It doesn’t make sense to treat as identical a month’s worth of releases which are all neutral tone in tone (sending no message) and a month’s worth of releases of which half are strongly positive and half are strongly negative (stoking uncertainty). Our sample of discretionary (non-required) news releases is drawn from those lodged with <a href="https://web.stevens.edu/hfslwiki/index.php?title=Thomson_Reuters_News_Analytics">Thomson Reuters News Analytics</a> between January 2003 to December 2015. It includes firms listed on the New York Stock Exchange, the AMEX American Stock Exchange and the NASDAQ technology-heavy exchange. The archive scores the tone of each release as positive, negative or neutral. We used the <a href="https://www.thomsonreuters.com/en/press-releases/2014/thomson-reuters-starmine-model-predicts-us-stock-performance.html">Thomson Reuters Insiders Filing Database</a> to obtain information on chief executive buying, limiting our inquiries to significant purchases of at least 100 shares. Strategic uncertainty About 70% of the chief executives proved to be opportunistic traders in the sense that they bought with no particular pattern, rather than at the same time every year. We found that news releases by these chief executives increased information uncertainty by 5.8% and 3.6% in the months before they bought and in the month they bought. In the months following their purchases, the positive to negative spread of their news releases returned to the average for non-purchase months. The unmistakable conclusion is that their behaviour is strategic. We obtained similar results when we used other measures of buying and the tone of news releases. Our results provide no evidence to support the contention that chief executives behave in this strategic way when selling shares. This is consistent with other findings suggesting that the timing of sales is often out of the hands of the sellers. <a href="https://scholar.google.com/scholar_lookup?title=Insider%20trading%20and%20voluntary%20disclosures&publication_year=2006&author=Q.%20Cheng&author=K.%20Lo">Previous studies</a> have found only <a href="https://scholar.google.com/scholar_lookup?title=Voluntary%20disclosures%20and%20insider%20transactions&publication_year=1999&author=C.F.%20Noe">weak links</a> between executive share purchases and the news they release to the market. This might be because those studies have looked for more easily detected (and more clearly problematic) negative news releases. But that’s an old and (with the advent of linguistic analysis) increasingly risky approach. Our research suggests that by saying many things at once chief executives can achieve much the same thing.

Riding on the kangaroo’s back: Animal skin fashion, exports and ethical trade

The Versace fashion house recently <a href="https://www.theguardian.com/world/2020/jan/15/versace-bans-kangaroo-skin-after-pressure-from-animal-activists">announced</a> it had stopped using kangaroo skins in its fashion collections after coming under pressure from animal rights group <a href="https://www.lav.it/en">LAV</a>. Kangaroo meat and skin has an annual production <a href="http://www.kangarooindustry.com/industry/economic/">value</a> of around A$174 million, with skins used in the fashion and shoe manufacturing industries. There are legitimate questions regarding the ethical manner in which kangaroos are killed. But Indigenous people have long utilised the skins of kangaroos and possums. Versace’s concerns may have been allayed by understanding more about our traditions and practices. Reviving skills There has always been concern around how native animals are treated while alive and how they are killed to cause as little distress, pain and suffering as possible. Campaigners say <a href="https://www.lav.it/en/news/australia-versace-kangaroos">2.3 million</a> kangaroos in Australia are hunted each year. Official <a href="https://www.environment.gov.au/biodiversity/wildlife-trade/natives/wild-harvest/kangaroo-wallaby-statistics/kangaroo-2000">sources</a> cite this figure as the national quota, but put the number actually killed at around 1.7 million. Australian Aboriginal people have for many thousands of years utilised native animals, predominantly kangaroos and possums. Consciously and sustainably, every part of the animal was used. The kangaroo meat was eaten, the skins used to make cloaks for wearing, teeth used to make needles, sinew from the tail used as thread. The cloaks were incised with designs on the skin side significant to the wearer representing their totems, status and kinship. Cloaks were made for babies and added to as the child grew into adulthood, and people were buried in their <a href="https://www.nationalquiltregister.org.au/aboriginal-skin-cloaks/">cloaks</a>when they died. Aboriginal women from New South Wales and Victoria have begun <a href="https://sydney.edu.au/museums/images/content/exhibitions-events/where-we-all-meet/djon-mundine-essay-sectioned.pdf">reviving</a> the tradition of kangaroo and possum skin cloak-making to pass down knowledge of this important practice to future generations. Interestingly, possum skins can only be purchased from New Zealand for these crafts. As an introduced species, they have wreaked havoc on NZ animal populations and the environment, but are a protected species in Australia. Culls and trade In Australia, kangaroos are not farmed but are harvested for meat and fur in the wild under a voluntary <a href="https://www.viva.org.uk/under-fire/cruelty-kangaroos">code of conduct</a>. The code is difficult to monitor and enforcement is <a href="http://s3.amazonaws.com/thinkk_production/resources/29/Kangaroo_Court_Enforcement_of_the_law_governing_commercial_kangaroo_killing_.pdf">complicated</a> by federal and state sharing of responsibility. This code is currently under <a href="https://www.agrifutures.com.au/kangaroo-commercial-code-review/">review</a>. The export and import of wildlife is <a href="https://www.environment.gov.au/biodiversity/wildlife-trade/natives">regulated</a> under Australia’s national environmental law, the Environment Protection and Biodiversity Conservation Act 1999 Act. In practice, kangaroos are shot in the wild by professional licensed shooters with an intended single shot to the head to kill them quickly. There are <a href="http://thinkkangaroos.uts.edu.au/issues/welfare-and-enforcement.html">concerns</a> over whether shooters should be trained better and whether nighttime shoots with poor visibility result in the killing of alpha males or mothers with joeys in their pouches. If mothers are accidentally shot, the code dictates the joey should be shot too. Sometimes the shot does not kill them instantly and they are then clubbed over the head. Traditionally, Aboriginal people speared kangaroos. This was unlikely to kill them instantly, so they were swiftly killed with a blow to the head by a boondi(wooden club). Why kangaroo? Kangaroo skin is extremely strong and more flexible than other leathers, including cow hide. It is routinely used in the production of soccer boots as they mould to the feet extremely well and don’t need to be worn in like harder leathers. This has led to an <a href="https://www.abc.net.au/news/2006-07-12/kangaroo-skin-hits-fashion-capitals/1799602">increase</a> in the use of kangaroo. LAV <a href="https://www.lav.it/en/news/australian-fire-our-actions-to-save-animals">reports</a> Italy is the biggest importer of kangaroo leather in Europe, where it is used to produce soccer shoes and motorbike suits. They are <a href="https://www.lav.it/en/news/australian-fire-our-actions-to-save-animals">lobbying</a> brands Lotto and Dainese to stop using kangaroo, arguing that shooting animals is not sustainable given the estimated <a href="https://theconversation.com/bushfires-left-millions-of-animals-dead-we-should-use-them-not-just-bury-them-129787">1 billion</a> creatures killed in bushfires this season. In terms of environmental sustainability, kangaroos cause less damage to the environment than cattle. Cows contribute methane gas, their hard hooves destroy the earth, they eat the grass to a point that it does not regenerate. Kangaroos eat the grass leaving a small portion to re-flourish, they bounce across the land without causing damage to it, and don’t produce methane gases. The use of kangaroo skins in fashion can be done ethically if the code is reviewed in consultation with Aboriginal people and enforced properly. The industry has the <a href="https://www.publish.csiro.au/an/EA03248">potential</a> to produce and support sustainable business opportunities for Aboriginal communities. While celebrities are <a href="https://www.idausa.org/campaign/wild-animals-and-habitats/fur/latest-news/kardashians-shamed-among-10-worst-celebrities-fur-animals/">shamed</a> for wearing fur fashion, this relates to the unregulated and inhumane treatment of coyotes, chinchillas, foxes, mink, rabbits, and other fur-bearing animals. In contrast, scientists <a href="https://www.publish.csiro.au/an/EA03248">consider</a> kangaroo harvest as “one of the few rural industry development options with potential to provide economic return with minimal environmental impact”. Only natural Versace, along with most fashion retailers across the high-end to ready-to-wear spectrum, use synthetic fibres in their fashion products. Such materials eventually <a href="https://theconversation.com/time-to-make-fast-fashion-a-problem-for-its-makers-not-charities-117977">cause more damage</a> to the environment than natural fibres and skins. They don’t biodegrade and many of these fibres end up in landfill, our oceans or in the <a href="https://www.sciencedirect.com/science/article/pii/S0269749119348808">stomachs of fish</a>. Animal skins will always be used in fashion and other products because of the unique properties the skins bring to design and function. While the bushfires have killed millions of Australian native animals, kangaroo culls are managed to have limited impact on the population. We should focus our energy on saving Australian native animals that are <a href="https://theconversation.com/australias-bushfires-could-drive-more-than-700-animal-species-to-extinction-check-the-numbers-for-yourself-129773">close to extinction</a> and lobbying for a stricter ethical code for shooters that can be legally enforced to ensure kangaroos are killed humanely.

Man offers to trade truck for liver to save his dying wife

A California man has taken to Facebook to make a desperate plea to help save his dying wife. Verlon Robinson, 55, offered to give away his pick-up truck and trailer to anyone who could donate a healthy section of liver that would save his wife. He even offered to throw in one of his kidneys to the deal. Verlon’s wife, Marie, suffers from cirrhosis of the liver. She is on an organ transplant waiting list but Verlon says he is worried she won’t get a liver in time. “To all that don’t know I have a very sick wife, with a non-reversible liver disease,” Verlon wrote in a post last week. “I do have an 04 Dodge pick-up that I would gladly trade anyone,” he said. “Plus I could throw in a nice tent trailer. “I would do anything to trade places with her but as you know that’s impossible. So please if you are O-positive or negative blood type and would consider giving her some of your liver we have insurance that would cover all surgeries. “PS I have good kidneys and I would throw in one.” <img width="439" height="585" src="http://cdn.newsapi.com.au/image/v1/989513d7a833c363a2f55297ca6176ee?width=650" alt="Man offers to trade truck for liver to save dying wife. Picture: Verlon Robinson/Facebook" style="display: block; margin-left: auto; margin-right: auto;"/> Verlon had to later change his proposal after being told it was “against the rules to offer my material stuff”. “Since most of you do not want my truck or trailer, it’s probably OK,” he quipped. “However they did say I could still offer my kidney. So kidney is still out there.”

This 93-year-old man traded in his skateboard to get $4000 off a car

When a 93-year-old man approaches a used car dealership, it’s not often you’d expect him to be carrying a skateboard. Enock Ernest Edwards had a chat to the salesmen at Fordthorne Motors about their advertised deal that promised “anything with four wheels can be part-exchanged”. He joked with the salesman that he should bring his old skateboard into the shop in order to grab a deal, as he didn’t use it anymore. Only, he wasn’t really joking. Salesman Jack Dunn was greeted again by Encok when he returned to the car yard later, holding a skateboard. Jack said “He was such a lovely man, and it was a very clever idea, so we went with it. He had so much energy that everyone loved talking to him, he showed no sign of letting his age stop him doing what he wanted.” The part-exchange deal made Enock eligible for a £2,000 discount, which converts to $4137.60 NZD. He bought an MG for £8,499, originally priced at £10,499.
