The way food is grown around the world threatens 24,000 of the 28,000 species that are at risk of extinction, according to a report published Wednesday that calls on world leaders to urgently reform the global food system.
Feeding the World
<p>The food system sits at the heart of four worsening global crises: climate, extinction, hunger and obesity. With more than a third of the world's land used for agriculture, experts are grappling with how to feed a growing population more food that is healthy — while at the same time killing less wildlife and emitting fewer <a href="https://www.dw.com/en/un-report-woefully-inadequate-climate-pledges-spell-32c-temperature-rise/a-55878680" target="_blank">greenhouse gases</a>.</p><p>For decades, environmental activists have held up organic farms, which avoid synthetic fertilizers and pesticides, as a nature-friendly alternative to conventional agriculture. Some farmers have turned to regenerative practices that store carbon dioxide in soils and make crops more resilient to storms and droughts.</p><p>But ecologists say there is a catch.</p>The Organic Dilemma
<p>Because <a href="https://www.dw.com/en/organic-farming-certificate-africa/a-52352517" target="_blank">organic</a> and regenerative farms typically yield less food per hectare than industrial farms, sustainable farmers need to use more land if they are to grow the same amount of food.</p><p>A 2019 <a href="https://www.nature.com/articles/s41467-019-12622-7" target="_blank">study</a> published in the journal Nature Communications found that adopting organic farming across the UK would, in fact, lead to more greenhouse gas emissions. Lower yields at home would be offset by imported food from croplands that would expand onto natural ecosystems.</p><p>In the US, a detailed lifecycle assessment of a regenerative farm found that its greenhouse gas emissions for each kilogram of meat were 66% lower than conventional alternatives, but took up 2.5 times more land, according to a <a href="https://www.frontiersin.org/articles/10.3389/fsufs.2020.544984/full" target="_blank" rel="noopener noreferrer">study</a> published in December in the journal Frontiers in Sustainable Food Systems.</p><p>Experts say there isn't enough land to feed the world and its growing appetite for meat through sustainable farms alone, even if they were built on marginal lands like degraded cropland.</p><p>The only thing that will allow us to farm in a sustainable way is changing our demand for food, said Benton. "That sounds horribly elitist, middle-class, 'let's all go vegan'," he said. But it could free up demand for land that could then be satisfied by sustainable farms. </p><p>Beef and a few other red meats, for instance, supply 1% of the world's calories but account for 25% of the emissions that come with changing how land is used, according to a <a href="https://www.nature.com/articles/s41586-020-03138-y" target="_blank">study</a> published in the journal Nature in January. To produce the same amount of protein as tofu, beef uses up 75 more times land.</p><p>In countries like Brazil and Indonesia, foreign demand for commodities drives companies to raze rainforests to grow soy for cattle and <a href="https://www.dw.com/en/indonesia-palmoil-deforestation-peatlands-fires-climate-change/a-53587027" target="_blank" rel="noopener noreferrer">oil palm</a> for cooking and use in processed foods.</p><p>In many cases, the food is not even eaten. About a third of all food made is lost during production or wasted.</p>Cheap, Unhealthy Food
<p>The charge sheet ecologists have against industrial agriculture is long: destroying forest homes of endangered mammals like orangutans; killing bees that farmers rely on to pollinate crops; chopping trees that suck CO2 out of the atmosphere; and degrading soils that future generations will need to feed themselves.</p><p>But doctors, too, are worried.</p><p>Expanding farmlands raises the risk of zoonotic diseases crossing from animals to humans. Factory farms pump antibiotics into livestock that encourages the growth of bacteria that are resistant to treatment. And then there's nutrition.</p><p>Obesity rates have tripled in the last half century amid a rise in foods high in fat and sugars and a fall in physical activity, bringing greater risk of heart disease and some cancers. The World Health Organization has called on the food industry to reduce the fat, sugar and salt content of processed foods, and make sure that healthy choices are affordable to everybody.</p><p>"Our current food system is a double-edged sword shaped by decades of the cheaper food paradigm," said Susan Gardner, Director of UNEP's Ecosystems Division. It aims to make more food, quickly and cheaply, without considering the costs to biodiversity and health, she said.</p><p>But at the same time, cheap food prices and productivity increases in agriculture have given more people access to food, said Irene Hoffman, Secretary of the Commission on Genetic Resources for Food and Agriculture at the UN's Food and Agriculture Organization (FAO), who was not involved in the report. "Otherwise, our current food insecurity index would be much, much higher."</p><p>The world population has doubled in the last 50 years to 7.8 billion people. While food production has kept up, 1 in 10 people today still go to bed hungry each night. By 2050, when the population is expected to reach nearly 10 billion people, the competition for land will be even greater because of efforts to grow plants to remove carbon dioxide from the atmosphere.</p><p>A landmark <a href="https://linkinghub.elsevier.com/retrieve/pii/S0140673618317884" target="_blank">study</a> published in the medical journal Lancet in 2019 found that world leaders could feed 10 billion people and still stay within a "safe operating space on Earth" by radically changing food production and shifting diets.</p><p>And doing so, the authors found, would make people healthier.</p><p>A move to healthy, sustainable diets would involve eating half as much red meat and sugar globally, and twice as many nuts, fruits, vegetables and legumes. It would avoid more than 7 million premature deaths per year, as well as reducing pressure on <a href="https://www.dw.com/en/biodiversity-sixth-mass-extinction-animals-plants-kew-conservation-species-gerardo-ceballos/a-55099955" target="_blank" rel="noopener noreferrer">nature</a>. </p><p>This, in turn, this would also make the farms more resilient to shocks like climate change, disease and soil erosion, safeguarding food supplies for the future.</p><p><span></span>"There's often a tendency to play nature against agriculture, which is absolutely not the case," said Hoffmann. "Agriculture depends on biodiversity, it is shaped by biodiversity [and] it manages biodiversity." </p><p><em>Reposted with permission from </em><em><a href="https://www.dw.com/en/farming-food-biodiversity-extinction-food-waste-health-meat-plant-based/a-56416006" target="_blank">Deutsche Welle</a>.</em></p>EcoWatch Daily Newsletter
Scientists Warn Humanity in Denial of Looming 'Collapse of Civilization as We Know It'
By Jessica Corbett
In an example to the rest of the scientific community and an effort to wake up people — particularly policymakers — worldwide, 17 scientists penned a comprehensive assessment of the current state of the planet and what the future could hold due to biodiversity loss, climate disruption, human consumption and population growth.
Like many other plant-based foods and products, CBD oil is one dietary supplement where "organic" labels are very important to consumers. However, there are little to no regulations within the hemp industry when it comes to deeming a product as organic, which makes it increasingly difficult for shoppers to find the best CBD oil products available on the market.

A few months ago a group of scientists warned about the rise of "extinction denial," an effort much like climate denial to mischaracterize the extinction crisis and suggest that human activity isn't really having a damaging effect on ecosystems and the whole planet.

<p><strong><a href="https://www.iucnredlist.org/species/123423283/123424374" target="_blank" rel="noopener noreferrer">Smooth handfish (<em>Sympterichthys unipennis</em>)</a></strong><strong> </strong>— One of the few extinctions of 2020 that received much <a href="https://www.scientificamerican.com/article/smooth-handfish-extinction-marks-a-sad-milestone/" target="_blank">media attention</a>, and it's easy to see why. Handfish are an unusual group of species whose front fins look somewhat like human appendages, which they use to walk around the ocean floor. The smooth species, which hasn't been seen since 1802, lived off the coast of Tasmania and was probably common when it was first collected by naturalists. Bottom fishing, pollution, habitat destruction, bycatch and other threats are all listed as among the probable reasons for its extinction. Even though the local fishery collapsed more than 50 years ago, the remaining handfish species are still critically endangered, so this extinction should serve as an important wake-up call to save them.</p><p><a href="https://therevelator.org/plant-species-extinct-america/" target="_blank"><strong>65 North American plants</strong></a> — This past year researchers set out to determine how many plants in the continental United States had been lost. They catalogued 65, including five small trees, eight shrubs, 37 perennial herbs and 15 annual herbs. Some of these had been reported before, but for most this is the first time they've been declared extinct. The list includes <a href="https://therevelator.org/extinction-hotspot-appalachia/" target="_blank" rel="noopener noreferrer"><em>Marshallia grandiflora</em></a>, a large flowing plant from the American Southeast that was declared its own species this past year.

Mites may not look or sound important, but they play key roles in their native ecosystems. If 15% of the world's 1.25 million mite species have been lost, we're talking more than 8,300 extinctions — a number the researchers predict will continue to rise.</p><p><a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/ibi.12839" target="_blank" rel="noopener noreferrer"><strong>Simeulue Hill mynas</strong></a> — An alarming paper called this an "extinction-in-process" of a previously undescribed bird that probably went extinct in the wild in the past two to three years due to overcollection for the songbird trade.

People Think the World’s Population Is Growing Too Fast – So Why Can’t We Talk About It
By Kelley Dennings
It's time to talk about something that most of us have been reluctant to face: what to do about the intensifying connection between population gain and environmental loss. A growing body of research shows continued human population growth equates to accelerating species extinction.
By Tara Lohan
A logged forest is a changed forest, and for woodland caribou that could mean the difference between life and death.

<p>But here's the twist: Moose do better in these disturbed landscapes, and that puts caribou further at risk, albeit indirectly.</p><p>Previous research has found that moose prefer the vegetation that grows in these early successional forests that follow a large-scale disturbance, like commercial logging. And a higher density of moose attracts more wolves, which are also able to <a href="https://besjournals.onlinelibrary.wiley.com/doi/full/10.1111/1365-2664.12732" target="_blank">move faster and hunt farther</a> by following linear clearings like roads and pipelines in these developed areas.</p><p>While moose are the primary prey for wolves, caribou that wander into these forests become another tasty target.</p><p>"The bottom line," Fryxell explains, "is that the combination of vegetation changes, increase in road density, increase in moose, and consequent increase in wolves threaten long-term viability of woodland caribou in boreal landscapes of Ontario, in a similar fashion to many other parts of Canada."</p><p>A national assessment found that around 70% of Canada's local <a href="http://registrelep-sararegistry.gc.ca/default.asp?lang=En&n=2FEAAC82-1#_ex" target="_blank">populations of woodland caribou were no longer self-sustaining</a>.</p><p>So what's to be done?</p><p>Last year provincial managers in Quebec floated the idea of <a href="https://www.nationalobserver.com/2019/12/11/news/quebec-plan-kill-wolves-protect-caribou-angers-conservationists" target="_blank">killing wolves</a> to protect caribou herds. Their idea met with public backlash, but wolves in British Columbia weren't so lucky. During the winter of 2019-2020, a whopping 463 wolves were killed by the B.C. provincial government for the stated purpose of protecting populations of southern mountain caribou, another caribou ecotype.</p><p>Some of the money to pay for the kill came from Coastal GasLink, a company actively clearing land in caribou habitat for a pipeline, the Canadian news outlet the <em><a href="https://thenarwhal.ca/a-dangerous-road-coastal-gaslink-pays-to-kill-wolves-in-endangered-caribou-habitat-in-b-c-interior/" target="_blank">Narwhal </a></em><a href="https://thenarwhal.ca/a-dangerous-road-coastal-gaslink-pays-to-kill-wolves-in-endangered-caribou-habitat-in-b-c-interior/" target="_blank">reported</a>.</p><p>And a <a href="https://link.springer.com/article/10.1007/s10531-020-02008-3" target="_blank">recently published study</a> in the journal <em>Biology and Conservation </em>found that the culls were not likely to aid caribou and pointed out several shortcomings in previous research that called for such wolf-control measures.</p><p>There are other, and better, options — like habitat protection and restoration.</p><p>Fryxell's study concluded that "the most secure conservation measure would be to set aside extensive tracts of boreal forest with natural patterns of disturbance to sustain viable caribou sub‐populations."</p><p>Research shows that the animals need at least 65% of their range undisturbed to have a good shot at survival.</p><p>And helping caribou will come with other environmental benefits. Canada's 2018 <a href="http://registrelep-sararegistry.gc.ca/default.asp?lang=En&n=2FEAAC82-1#_ex" target="_blank">federal action</a> plan to restore caribou stated, "Boreal caribou is also considered by many to be an indicator of the overall state of Canada's boreal forest ecosystem." So keeping forests intact or restoring habitat is a proposition that would benefit not only caribou but many other species.</p><p><em><a href="https://therevelator.org/author/taralohan/" target="_blank">Tara Lohan</a> is deputy editor of The Revelator and has worked for more than a decade as a digital editor and environmental journalist focused on the intersections of energy, water and climate.

In most cases an extinction takes decades of slow attrition and population declines — a death by a thousand cuts.
Sometimes, though, a species can nearly vanish in the blink of an eye.

<p>"I don't know of any similar wildlife mortality like this," says ecologist Bruce Chessman of the University of New South Wales-Sydney. "Of course, the chytrid fungus has wiped out some amphibian species quickly, but I don't know of anything equivalent with turtles."</p><p>Chessman served as the lead author of a <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/aqc.3258" target="_blank">recent paper</a> that provided an estimate of the Bellinger River snapping turtle's precipitous decline. "There's a lot of uncertainty because, as the paper says, trying to get a reliable estimate of a very rare species over 70 kilometers of river is quite challenging. But we think it's about 150-200 animals remaining. The risk of extinction is real because of the small number left."</p>Virus-plus?
<p>The researchers also examined several hypotheses about how a previously unknown and still unidentified virus could have killed so many turtles so quickly.</p><p>They didn't find much.</p><p>"It's all a bit of a mystery," Chessman says. "There's still so much we don't know. We know it's a reptile type of virus, but we have no idea where it came from, how long it's been in the Bellinger River, or how it managed to apparently spread upstream rather than downstream at a rate of up to a kilometer a day, which is really quite bizarre."</p><p><a href="https://www.sciencedirect.com/science/article/abs/pii/S0006320717305335#!" target="_blank">Previous research</a> had suggested that some additional contributing factor — perhaps abnormal water temperatures, pollution or malnutrition — may have magnified the effects of the virus so that it caused so many fatalities. Current research, however, has found no specific evidence to support those hypotheses — at least, not yet.</p><p>"We can't rule out that some sort of unusual environmental conditions in the preceding months were related to it somehow, but we don't really have the information to understand what that was or what it may have been," says Chessman. "Unfortunately, there isn't that much information about what happened in the river until these sick and dead turtles started showing up in February 2015."</p>The Bellinger River in September 2019.

<p>Even our understanding of the virus — what it does and how it kills — continues to lag.</p><p>"Because the species is so critically endangered now, it's not permissible to try infection trials with the few adults that are remaining," Chessman explains. "So it's still not possible to get that experimental confirmation about what infection with the virus really does to the turtles."</p><p>All of this leaves the teams working to conserve the turtles with a great deal of uncertainty.</p><p>"We really don't know what the prospects are in terms of further disease outbreak and mortality," Chessman says. The few remaining turtles also face threats from predators, mostly introduced red fox, as well as from native species such as monitor lizards.</p><p>There's also a genetic threat. Another Australian turtle species, the Macquarie turtle (<em>Emydura macquarii</em>), appeared in the Bellinger River in recent years. The newcomers are slightly more aggressive than the native species, so they outcompete them for food, and there's evidence they've started to breed and hybridize with Bellinger River snapping turtles.</p><p>"The challenges are ahead," Chessman says. "But everyone's giving it their best."</p><p>That "everyone" includes the NSW Department of Planning Industry and Environment, other government organizations, local conservation groups and experts around the world.</p><p>And that collaboration may represent hope for the species.</p>The Last Chance Leads to the Next Generation
<p>After his first warnings reportedly fell on deaf ears, Rowan Simon and another friend returned to the river, where they gathered up 50 dead and dying turtles and presented them to the local council.</p><p>The collection process "was pretty horrific," Rowan told the <em>Sydney Morning Herald</em>.</p><p>That confrontation finally motivated action. But by then — just two months after the first signs of the disease — very few turtles were left.</p><p>At the last minute, conservation teams rescued 17 healthy mature and immature Bellinger River snapping turtles from an upper stretch of the river the disease hadn't yet reached. They soon became the core of a captive-breeding population at Sydney's Taronga Zoo. Another 19 immature turtles (also healthy) were collected in November 2016 and sent to Symbio Wildlife Park to start a second captive-assurance population.</p>A recent hatchling identified with a unique dab of paint. Photo courtesy NSW Department of Planning, Industry and Environment
<p>That effort has paid off — and probably saved the species from extinction.</p><p>The captive turtles promptly got down to business and started breeding. Today more than 130 healthy turtles live at the two breeding facilities. Taronga Zoo announced the birth of the most recent <a href="https://taronga.org.au/media-release/2020-03-16/baby-boom-bellinger-river-snapping-turtle" target="_blank">35 turtle babies</a> this past May.</p><p>More importantly, 20 captive-born animals have been released back into the river, where they're <a href="https://www.facebook.com/watch/?v=1428427787362202" target="_blank">constantly monitored</a> through surveys and radio transmitters.</p>A Long Road Ahead
<p>Of course, you need to produce a huge number of hatchlings to make up for losing 90% of a species. That will take time — a lot of it — and the effort faces some very strict physical limitations.</p><p>For one thing, very few mature females remain — just 5% of the total wild population. On top of that, 88% of the remaining turtles are immature, meaning they won't reach breeding age for several years — another 10-12 years in the case of the released hatchlings.</p>Two Bellinger River snapping turtle hatchlings. Photo courtesy NSW Department of Planning, Industry and Environment
<p>That means it would take decades for the population to come anywhere close to recovery even if the zoos keep producing and releasing young, and if the virus doesn't have a resurgence.</p><p>That timeline shouldn't come as a surprise, as it often takes decades for threatened species to recover once (or if) the threat that put them at risk is contained. As examples, the Chessman team's paper points out the difficulties faced by two other turtle species that faced enormous declines:</p><p><em>…a population of northern map turtles (</em>Graptemys geographica<em>) in the USA took 27 years to recover after a period of harvesting in which abundance declined by ~50% … and there was no recovery of a common snapping turtle (</em>Chelydra serpentina<em>) population in Canada 23 years after loss of 39% of nesting females to predation by otters…</em></p><p>For now, though, the Bellinger River snapping turtle's declines have ceased.</p><p>The biggest question, though, is whether that status quo will persist.</p><p>"The means of recovery are in place, potentially, but there's ongoing uncertainty about further mortality from disease," says Chessman. "We just don't know really what's going to happen to these young turtles that are being released once they reach maturity. Will they then succumb to the disease and die, or was it perhaps more of a one-off event?"</p><p>Other uncertainties include the potential threat of more bushfires like the ones Australia experienced earlier this year. Several media reports have suggested <a href="https://m.gulf-times.com/story/653574/Frightening-amount-of-world-heritage-area-burned-in-Australia" target="_blank">debris from the fires fell into the Bellinger River</a>, potentially affecting the turtles' food supplies. (Despite more than four months of inquiries, the NSW Department of Planning, Industry and Environment's public affairs office would not answer questions about how the fires may have affected the river.)</p>Extinction Inspiration
<p>Although we don't know much about the river basin's water quality before the turtles got sick, we know a lot more about it now — because this near-extinction has motivated the community.</p><p>Soon after news of the virus and mass turtle deaths emerged, a group of citizens banded together to form <a href="http://www.ozgreen.org/br" target="_blank">Bellingen Riverwatch</a> (named after the nearby town with a slightly different name than the river itself). Now community volunteers, schools and other organizations conduct monthly water-quality tests across three rivers, a process that's continued even amid the pandemic.</p>Bellingen Riverwatch uses an icon of the critically endangered Bellinger River snapping turtle in its logo.
<p>But the <a href="https://us19.campaign-archive.com/?u=30dee497e9a546ac8f61f1f67&id=dc0186b4c3" target="_blank">most recent Riverwatch report</a>, published June 24, found the river to be in "great" shape, with no visible pollution in most sites and only slight rises in certain phosphate levels or algae in others.</p>Swimming Forward
<p>Although many questions remain, the Bellinger River snapping turtle appears to have been saved from extinction — for now.</p><p>Of course, the threat of another potential outbreak still looms large — as it does for other wildlife species and even people around the world.</p><p>"Situations like this are of course unpredictable and could in theory happen anytime and anywhere — kind of like COVID," says biologist Craig Stanford, the lead author of a new study about <a href="https://www.sciencedirect.com/science/article/abs/pii/S0960982220306369" target="_blank">the threats faced by the world's turtle and tortoise species</a>. What's happening with the Bellinger River turtle, he says, "concerns all of us, but it's hard to take lessons from it to prevent something like this from happening in the future."</p><p>But there's one lesson from the Bellinger River that we can all carry forward: If you see a turtle or other animal that's displaying signs of illness or unusual behavior, raise the alarm. It could be the start of something catastrophic — and an opportunity to bring a coalition and a community together to fight for a good cause and make a difference.</p><p><em><a href="https://therevelator.org/author/john/" target="_blank">John R.

It takes a lot of effort and more than a little bit of luck for researchers like André Raine to get to the remote mountaintops of Kauai, where they're working to save endangered Hawaiian seabirds from extinction.

<p>So, unfortunately, do several species of invasive predators — including feral cats, black rats and feral pigs — that have put these ground-nesting birds, and so many other native Hawaiian species, on the fast track toward extinction.</p><p>"People are always really surprised by this," Raine said, "but it doesn't matter how remote the area, or how apparently inhospitable it is to predators like cats. You're going to find cats and rats and pigs in these areas. There wasn't a single site that we work in that doesn't have all these predators, busy eating the birds."</p>An endangered chick in the mouth of a feral cat. Courtesy Kaua'i Endangered Seabird Recovery Project
<p>Like many island endemics, Hawaii's bird species grew up without mammalian predators, so they're ill-adapted to the teeth and claws that arrived with human society. The cats descended from housecats, while pigs escape from agricultural sites and rats descended from stowaways on ships.</p><p>That's why the Kaua'i Endangered Seabird Recovery Project has spent the past nine years constructing fences and establishing other predator controls — work that is proving essential in giving these native birds a chance.</p><p>The first step in controlling predators is quantifying the threat.</p><p>According to a paper Raine and his colleagues published earlier this year in <a href="https://wildlife.onlinelibrary.wiley.com/doi/full/10.1002/jwmg.21824" target="_blank">The Journal of Wildlife Management</a>, introduced predators killed at least 309 endangered seabirds at six monitored breeding colonies between 2011 and 2017. That's quite a blow for each of these endangered species.</p><p>"Newell's shearwaters and Hawaiian petrels have suffered catastrophic declines over the last few decades," Raine said. "Any chick that's lost in the population is one that we can't afford to lose."</p>Hawaiian petrel. © Ken Chamberlain, some rights reserved (CC-BY-NC). Via iNaturalist.
<p>The researchers took on the sad task of collecting the dead and examining the wound patterns to determine which type of predator made the kill.</p><p>Rats, it turned out, killed the most — more than 50% of mortalities — usually from entering the birds' rocky burrows and eating eggs and chicks. That dramatically slows recovery efforts, but the research shows that adult birds who've lost their chicks returned to the same burrows the following year to try again.</p>Fence Me In
<p>Over the past decade, the Kaua'i Endangered Seabird Recovery Project and its many organizational partners have concentrated on establishing predator controls at six of their seven regularly monitored seabird breeding sites.</p><p>Again, this isn't easy to accomplish in these remote, rarely visited locations. Materials must be flown in, ungulate-proof fences built, other traps set, and pig-hunting expeditions organized. All of it must be accomplished and maintained in precarious territory full of wet vegetation, narrow ridgelines and steep canyon walls.</p><p>To make things even more difficult, the human visitors must leave the habitat as undisturbed as possible.</p><p>"If you start making trails in these areas, then you're basically just opening them up to the hordes of predators that are out there," Raine says.</p><p>But the hard work pays off.</p><p>According to the paper, fences and other controls not only keep the invasive predators out, they give the birds the opportunity to thrive.</p><p>The research team used seven years data from the six sites, from before and after predator controls were established, and projected striking results for the future of the two seabird species.</p><p>The first model looked at what would happen to each site without predator controls. It was a disaster — mostly due to cats. "We ran that for 50 years, and we found that all of the colonies dwindle toward extinction."</p><p>The paper, in what Raine acknowledges as gallows humor, calls this the <em>CATastrophe</em> model.</p><p>The second modeling approach incorporated data from successful breeding that took place after more extensive predator controls (fences and traps) were put in place. "We found that the populations increased over those 50 years," Raine said. Under the model, which was based on 2017 population growth rates at sites with predator controls, most sites would see a 50-60% increase over the 50-year projection, while one site more than doubled.</p><p>"It really does show that if you remove the predators, the birds will begin to recover."</p>By Alexander Richard Braczkowski, Christopher O'Bryan, Duan Biggs, and Raymond Jansen
Pangolins are one of the most illegally trafficked animals on the planet and are suspected to be linked to the current coronavirus pandemic.
A Cute But Threatened Species
<p><a href="https://www.worldwildlife.org/stories/what-is-a-pangolin" target="_blank">Pangolins</a> are the only mammals wholly-covered in scales, which they use to protect themselves from predators. They can also curl up into a tight ball.</p><p>They eat mainly ants, termites and larvae which they pick up with their sticky tongue. They can grow up to 1m in length from nose to tail and are sometimes referred to as scaly anteaters.</p><p>But <a href="https://www.sciencedirect.com/science/article/pii/B9780128155073000332" title="Chapter 33 - Conservation strategies and priority actions for pangolins" target="_blank">all eight</a> pangolin species are classified as "<a href="https://www.pangolins.org/tag/endangered-species/" target="_blank">threatened</a>" under International Union for Conservation of Nature <a href="https://www.iucnredlist.org/search?query=pangolin&searchType=species" target="_blank">criteria</a>.</p><p>There is an unprecedented demand for their scales, primarily from countries in Asia and <a href="https://conbio.onlinelibrary.wiley.com/doi/10.1111/conl.12389" title="Assessing Africa‐Wide Pangolin Exploitation by Scaling Local Data" target="_blank">Africa</a> where they are used in food, cultural remedies and <a href="https://www.nature.com/articles/141072b0" title="Chinese Medicine and the Pangolin" target="_blank">medicine</a>.</p><p>Between 2017 and 2019, seizures of pangolin scales <a href="https://www.nationalgeographic.com/animals/2020/02/pangolin-scale-trade-shipments-growing/" target="_blank">tripled in volume</a>. In 2019 alone, 97 tons of pangolin scales, equivalent to about 150,000 animals, were <a href="https://oxpeckers.org/2020/03/nigeria-steps-up-for-pangolins/" target="_blank">reportedly</a> intercepted leaving Africa.</p>Reintroduction of an Extinct Species
<p>Each year in South Africa the African Pangolin Working Group (<a href="https://africanpangolin.org/" target="_blank">APWG</a>) retrieves between 20 and 40 pangolins through intelligence operations with security forces.</p><p>These pangolins are often-traumatised and injured and are admitted to the <a href="http://www.johannesburgwildlifevet.com/our-hospital" target="_blank">Johannesburg Wildlife Veterinary Hospital</a> for extensive medical treatment and rehabilitation before they can be considered for release.</p><p>In 2019, seven rescued Temminck's pangolins were reintroduced into South Africa's <a href="https://www.andbeyond.com/destinations/africa/south-africa/kwazulu-natal/phinda-private-game-reserve/" target="_blank">Phinda Private Game Reserve</a> in the KwaZulu Natal Province.</p><p>Nine months on, five have survived. This reintroduction is a world first for a region that last saw a viable population of this species in the 1980s.</p><p>During the release, every individual pangolin followed a strict regime. They needed to become familiar with their new surroundings and be able to forage efficiently.</p>A ‘Soft Release’ in to the Wild
<p>The process on Phinda game reserve involved a more gentle ease into re-wilding a population in a region that had not seen pangolins for many decades.</p><p>The soft release had two phases:</p><ol><li>a pre-release observational period</li><li>an intensive monitoring period post release employing GPS satellite as well as VHF tracking tags.</li></ol>Why Pangolin Reintroduction is Important
<p>We know so little about this group of mammals that are vastly understudied and hold many secrets yet to be discovered by science but are on the verge of collapse.</p><p>The South African and Phinda story is one of hope for the Temminck's pangolin where they once again roam the savanna hills and plains of Zululand.</p><p>The process of relocating these trade animals back into the wild has taken many turns, failures and tribulations but, the recipe of the "soft release" is working.</p>- 10 Facts About Pangolins on World Pangolin Day - EcoWatch ›

At several points in the history of our planet, increasing amounts of carbon dioxide in the atmosphere have caused extreme global warming, prompting the majority of species on Earth to die out.
Past Mass Extinctions
<p>Many species can adapt to slow, or even moderate, environmental changes. But Earth's history shows that extreme shifts in the climate can cause many species to <a href="https://www.abc.net.au/news/2019-11-13/what-is-a-mass-extinction-are-we-in-one-now/11699372" target="_blank">become extinct</a>.</p><p>For example, about 66 million years ago an asteroid hit Earth. The subsequent smashed rocks and widespread fires released massive amounts of carbon dioxide over <a href="https://www.pnas.org/content/99/12/7836" target="_blank">about 10,000 years</a>. Global temperatures soared, sea levels rose and oceans became acidic. About <a href="https://www.britannica.com/science/K-T-extinction" target="_blank">80% of species</a>, including the dinosaurs, were wiped out.</p><p>And about 55 million years ago, global temperatures spiked again, over <a href="https://www.nature.com/articles/ngeo578;%20https://www.nature.com/articles/ngeo1179;https://www.whoi.edu/fileserver.do?id=136084&pt=2&p=148709" target="_blank">100,000 years or so</a>. The cause of this event, known as the <a href="https://www.britannica.com/science/Paleocene-Eocene-Thermal-Maximum" target="_blank">Paleocene-Eocene Thermal Maximum</a>, is not entirely clear. One theory, known as the <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2010RG000326" target="_blank">"methane burp" hypothesis</a>, posits that a massive volcanic eruption triggered the sudden release of methane from ocean sediments, making oceans more acidic and killing off many species.</p><p>So is life on Earth now headed for the same fate?</p>Comparing Greenhouse Gas Levels
<p>Before industrial times began at the end of the 18th century, carbon dioxide in the atmosphere sat at around <a href="https://data.giss.nasa.gov/modelforce/ghgases/" target="_blank">300 parts per million</a>. This means that for every one million molecules of gas in the atmosphere, 300 were carbon dioxide.</p><p>In February this year, atmospheric carbon dioxide reached <a href="https://www.esrl.noaa.gov/gmd/ccgg/trends/" target="_blank">414.1 parts per million</a>. Total greenhouse gas level — carbon dioxide, methane and nitrous oxide combined — reached almost <a href="https://www.esrl.noaa.gov/gmd/aggi/" target="_blank">500 parts per million of carbon dioxide-equivalent</a></p>Author provided / The Conversation /CC BY-ND
<p>Carbon dioxide is now pouring into the atmosphere at a rate of <a href="https://www.esrl.noaa.gov/gmd/ccgg/trends/" target="_blank">two to three parts per million each year</a>.</p><p>Using carbon records stored in fossils and organic matter, I have determined that current carbon emissions constitute an extreme event in the recorded history of Earth.</p><p><a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/gcb.13342" target="_blank">My research</a> has demonstrated that annual carbon dioxide emissions are now faster than after both the asteroid impact that eradicated the dinosaurs (about 0.18 parts per million CO2 per year), and the thermal maximum 55 million years ago (about 0.11 parts per million CO2 per year).</p>An asteroid wiped out the dinosaurs 66 million years ago.

The Next Mass Extinction Has Begun
<p>Current atmospheric concentrations of carbon dioxide are not yet at the levels seen 55 million and 65 million years ago. But the massive influx of carbon dioxide means the climate is changing faster than many plant and animal species <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/gcb.13342" target="_blank">can adapt</a>.</p><p><a href="https://www.un.org/sustainabledevelopment/blog/2019/05/nature-decline-unprecedented-report/" target="_blank">A major United Nations report</a> released last year warned around one million animal and plant species were threatened with extinction. Climate change was listed as one of five key drivers.</p><p>The report said the distributions of 47% of land-based flightless mammals, and almost 25% of threatened birds, may already have been negatively affected by climate change.</p><p>Many researchers fear the climate system is approaching a <a href="https://www.pnas.org/content/115/33/8252" target="_blank">tipping point</a> - a threshold beyond which rapid and irreversible changes will occur. This will create a cascade of <a href="https://sites.hks.harvard.edu/sed/docs/hjs_esa_environment_0510.pdf" target="_blank">devastating effects</a>.</p><p>There are already signs tipping points have been reached. For example, <a href="https://www.theguardian.com/environment/2018/feb/27/arctic-warming-scientists-alarmed-by-crazy-temperature-rises" target="_blank">rising Arctic temperatures</a> have led to <a href="https://www.jpl.nasa.gov/news/news.php?feature=7616" target="_blank">major ice melt</a>, and weakened the <a href="https://www.globalresearch.ca/melting-ice-sheets-and-weakened-polar-fronts-onset-of-climate-tipping-points/5668981" target="_blank">Arctic jet stream</a> — a powerful band of westerly winds.</p>A diagram showing the weakening Arctic jet stream, and subsequent movements of warm and cold air.

<p>This allows north-moving warm air to cross the polar boundary, and cold fronts emanating from the poles to <a href="https://link.springer.com/article/10.1007%2Fs10584-019-02458-x" target="_blank">intrude south into Siberia, Europe and Canada</a>.</p><p>A shift in climate zones is also causing the tropics to expand and migrate toward the poles, at a rate of about <a href="https://theconversation.com/the-worlds-tropical-zone-is-expanding-and-australia-should-be-worried-77701" target="_blank">56 to 111 kilometres per decade</a>.

Guam Rails Are No Longer Extinct in the Wild (Something Only One Other Bird Can Claim)
By Jason Bittel
When you walk into the tropical rainforest room at the National Aviary in Pittsburgh, the first thing you'll probably notice are the hyacinth macaws perched in mango trees. The feathers of these massive parrots are so impossibly blue that the birds look like birthday party piñatas. And the first thing you'll likely hear is the trill of the much tinier laughing thrushes as they swoop from tall cacao plants to the indoor-jungle floor. But watch out for Gus! He's the blue-headed great argus pheasant who likes to commandeer the walkway while unfurling his four-foot-tall fan of feathers in an attempt to woo female pheasants.
The U.S. Fish and Wildlife Service and the Department of the Interior have failed to protect 241 plant and animal species under the Endangered Species Act, according to a federal lawsuit filed last week by the Center for Biological Diversity, as Bloomberg Environment reported.
