Is humanity doomed? If in 2030 we have not reduced emissions in a way that means we stay under say 2℃ (I've frankly given up on 1.5℃), are we doomed then?

<p>Humanity is not doomed, not now or even in a worst-case scenario in 2030. But avoiding doom — either the end or widespread collapse of civilization — is setting a pretty low bar. We can aim much higher than that without shying away from reality.</p><p>It's right to focus on global warming of 1.5℃ and 2℃ in the first instance.

Good Reasons Not to Give Up Just Yet
<p>The <a href="https://www.ipcc.ch/" target="_blank">Intergovernmental Panel on Climate Change</a> described the effects of a 1.5℃ increase in average temperatures in a <a href="https://www.ipcc.ch/sr15/" target="_blank">special report</a> last year. They are also nicely summarized in an article about <a href="https://climate.nasa.gov/news/2865/a-degree-of-concern-why-global-temperatures-matter/" target="_blank">why global temperatures matter</a>, produced by NASA.</p><p>The global average temperature is currently about <a href="https://climate.nasa.gov/vital-signs/global-temperature/" target="_blank">1.2℃</a> higher than what it was at the time of the Industrial Revolution, some 250 years ago. We are already witnessing localized impacts, including the <a href="https://theconversation.com/we-just-spent-two-weeks-surveying-the-great-barrier-reef-what-we-saw-was-an-utter-tragedy-135197" target="_blank">widespread coral bleaching</a> on Australia's Great Barrier Reef.</p><img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzUyMzU1My9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYzNzgxMjE4OX0.IJqJXZa1yVyysYGVhkKXlgnwj-9ECS5oLDMfJeYA4A4/img.jpg?width=980" id="d2359" class="rm-shortcode" data-rm-shortcode-id="d17a07b33871ae3e0157b9db2ed9661d" data-rm-shortcode-name="rebelmouse-image" />
This graph shows different emission pathways and when the world is expected to reach global average temperatures of 1.5℃ or 2℃ above pre-industrial levels. Global Carbon Project, Author provided
<p>Limiting warming to 1.5℃ requires <a href="https://www.unenvironment.org/news-and-stories/press-release/cut-global-emissions-76-percent-every-year-next-decade-meet-15degc" target="_blank">cutting global emissions by 7.6% each year</a> this decade. This does sound difficult, but there are reasons for optimism.</p><p>First, it's possible technically and economically. For example, the use of <a href="https://en.wikipedia.org/wiki/Wind_power" target="_blank">wind</a> and <a href="https://en.wikipedia.org/wiki/Solar_power" target="_blank">solar</a> power has grown exponentially in the past decade, and their prices have plummeted to the point where they are now among the <a href="https://www.irena.org/publications/2020/Jun/Renewable-Power-Costs-in-2019" target="_blank">cheapest</a> sources of electricity. Some areas, including energy storage and industrial processes such as steel and cement manufacture, still need further research and a drop in price (or higher carbon prices).</p><p>Second, it's possible politically. Partly in response to the <a href="https://unfccc.int/process-and-meetings/the-paris-agreement/the-paris-agreement" target="_blank">Paris Agreement</a>, a growing number of countries have adopted stronger targets. <a href="https://www.wri.org/blog/2019/09/what-does-net-zero-emissions-mean-6-common-questions-answered" target="_blank">Twenty countries</a> and regions (including <a href="https://www.mfe.govt.nz/climate-change/zero-carbon-amendment-act" target="_blank">New Zealand</a> and the European Union) are now targeting net zero emissions by 2050 or earlier.</p><p>A recent example of striking progress comes from Ireland – a country with a similar emissions profile to New Zealand. The incoming coalition's "<a href="https://www.irishtimes.com/news/ireland/irish-news/programme-for-government-what-are-the-main-points-in-the-five-year-plan-1.4279046" target="_blank">program for government</a>" includes emission cuts of 7% per year and a reduction by half by 2030.</p><p>Third, it's possible socially. Since 2019, we have seen the massive growth of the <a href="https://theconversation.com/climate-change-children-are-carving-out-a-place-in-politics-now-adults-must-listen-and-act-123704" target="_blank">School Strike 4 Climate</a> movement and an increase in fossil fuel <a href="https://gofossilfree.org/divestment/commitments/" target="_blank">divestment</a>. Several media organizations, including The Conversation, have made a <a href="https://theconversation.com/media-impartiality-on-climate-change-is-ethically-misguided-and-downright-dangerous-130778" target="_blank">commitment to evidence-based coverage of climate change</a> and calls for a <a href="https://www.nytimes.com/2019/02/21/climate/green-new-deal-questions-answers.html" target="_blank">Green New Deal</a> are coming from a range of political parties, especially in the U.S. and Europe.</p><p>There is also a growing understanding that to ensure a safe future we need to consume less overall. If these trends continue, then I believe we can still stay below 1.5℃.</p>
The Pessimist Perspective
<p>Now suppose we don't manage that. It's 2030 and emissions have only fallen a little bit. We're staring at 2℃ in the second half of the century.</p><p>At 2℃ of warming, we could expect to lose more than 90% of our coral reefs. Insects and plants would be at higher risk of extinction, and the number of dangerously hot days would increase rapidly.</p><p>The challenges would be exacerbated and we would have new issues to consider. First, under the "<a href="https://news.mongabay.com/2009/06/proving-the-shifting-baselines-theory-how-humans-consistently-misperceive-nature/" target="_blank">shifting baseline</a>" phenomenon — essentially a failure to notice slow change and to value what is already lost — people might discount the damage already done. Continuously worsening conditions might become the new normal.</p><p><span></span>Second, climate impacts such as mass migration could lead to a rise of nationalism and make international cooperation harder. And third, we could begin to pass unpredictable "<a href="https://www.nature.com/articles/d41586-019-03595-0" target="_blank">tipping points</a>" in the Earth system. For example, warming of more than 2°C could set off widespread melting in Antarctica, which in turn would contribute to sea level rise.</p><p>But true doom-mongers tend to assume a worst-case scenario on virtually every area of uncertainty. It is important to remember that such scenarios are not very likely.</p><p><span></span>While bad, this 2030 scenario doesn't add up to doom — and it certainly doesn't change the need to move away from fossil fuels to low-carbon options.</p>From Your Site Articles

A landmark study by Global FinPrint reveals sharks are absent on many of the world's coral reefs, indicating they are functionally extinct. Global FinPrint
By JoAnn Adkins
A landmark study by Global FinPrint reveals sharks are absent on many of the world's coral reefs, indicating they are functionally extinct — too rare to fulfill their normal role in the ecosystem.
<p>Of the 371 reefs surveyed in 58 countries, sharks were not observed on nearly 20 percent, indicating a widespread decline that has gone undocumented on this scale until now. The Global FinPrint team, led by researchers at Florida International University (FIU), also identified conservation measures that could lead to recovery of these iconic predators.</p><p>Essentially no sharks were detected on any of the reefs in the Dominican Republic, the French West Indies, Kenya, Vietnam, the Windward Dutch Antilles and Qatar. Among these, a total of only three sharks were observed during more than 800 survey hours, according to the study published today in <a href="https://www.nature.com/articles/s41586-020-2519-y#https://www.nature.com/articles/s41586-020-2519-y" target="_blank"><em>Nature</em></a>.</p><p>"While Global FinPrint results exposed a tragic loss of sharks from many of the world's reefs, it also shows us signs of hope," said Jody Allen, co-founder and chair of the Paul G. Allen Family Foundation. "The data collected from the first-ever worldwide survey of sharks on coral reefs can guide meaningful, long-term conservation plans for protecting the reef sharks that remain."</p>
<p>This benchmark for the status of reef sharks around the world reveals an alarming global loss of these iconic species that are important food resources, tourism attractions, and top predators on coral reefs. Their loss is due in large part to overfishing of sharks, with the single largest contributor being destructive fishing practices, such as the use of longlines and gillnets.</p><p>"Although our study shows substantial negative human impacts on reef shark populations, it's clear the central problem exists in the intersection between high human population densities, destructive fishing practices, and poor governance," said <a href="https://case.fiu.edu/about/directory/profiles/chapman-demian.html" target="_blank">Demian Chapman</a>, Global FinPrint co-lead, associate professor in <a href="https://case.fiu.edu/biology/" target="_blank">FIU's Department of Biological Sciences</a> and researcher in the Institute of Environment. "We found that robust shark populations can exist alongside people when those people have the will, the means, and a plan to take conservation action."</p><p>The study revealed several countries where shark conservation is working and the specific actions that can work. The best performing nations compared to the average of their region included Australia, the Bahamas, the Federated States of Micronesia, French Polynesia, the Maldives and the United States. These nations reflect key attributes that were found to be associated with higher populations of sharks — being generally well-governed and either banning all shark fishing or having strong, science-based management limiting how many sharks can be caught.</p>
<p>"These nations are seeing more sharks in their waters because they have demonstrated good governance on this issue," said Aaron MacNeil, lead author of the Global FinPrint study and associate professor at Dalhousie University. "From restricting certain gear types and setting catch limits, to national-scale bans on catches and trade, we now have a clear picture of what can be done to limit catches of reef sharks throughout the tropics."</p><p>The FinPrint team is wrestling with the fact that conservation action on sharks alone can only go so far. Researchers are now looking at whether recovery of shark populations requires management of the wider ecosystem to ensure there are enough reef fish to feed these predators.</p><p>"Now that the survey is complete, we are also investigating how the loss of sharks can destabilize reef ecosystems," said <a href="https://case.fiu.edu/about/directory/profiles/heithaus-michael.html" target="_blank">Mike Heithaus</a>, Global FinPrint co-lead and dean of the <a href="https://case.fiu.edu/index.html" target="_blank">College of Arts, Sciences & Education</a> at Florida International University. "At a time when corals are struggling to survive in a changing climate, losing reef sharks could have dire long-term consequences for entire reef systems."</p>
<p>Launched in the summer of 2015, Global FinPrint's data were generated from baited remote underwater video stations (BRUVS) that consist of a video camera placed in front of a standard amount of bait – a "Chum Cam." Coral reef ecosystems were surveyed with BRUVS in four key geographic regions: The Indo-Pacific, Pacific, the Western Atlantic and the Western Indian Ocean.</p><p>Over the course of four years, the team captured and analyzed more than 15,000 hours of video from surveys of 371 reefs in 58 countries, states and territories around the world. The work was conducted by hundreds of scientists, researchers, and conservationists organized by a network of collaborators from Florida International University, the Australian Institute of Marine Science, Curtin University, Dalhousie University, and James Cook University.</p><p>For more information and a new global interactive data-visualized map of the Global FinPrint survey results, visit <a href="https://globalfinprint.org/" target="_blank">https://globalfinprint.org</a>.</p>

If world governments don't act to reduce greenhouse gas emissions, most polar bear populations will not survive the century, a new study has found.
<p>Polar bears, who rely on <a href="https://www.ecowatch.com/tag/arctic" target="_self">Arctic</a> <a href="https://www.ecowatch.com/tag/sea-ice" target="_self">sea ice</a> to hunt for seals, have long been a symbol of the impacts of the <a href="https://www.ecowatch.com/climate-change/" target="_self">climate crisis</a>. As the ice melts, they lose the ability to sustain themselves.</p><p>"Polar bears are already sitting at the top of the world; if the ice goes, they have no place to go," lead study author and University of Toronto Scarborough biologist Péter Molnár told <a href="https://www.bbc.co.uk/news/amp/science-environment-53474445" target="_blank">BBC News</a>.</p>
<blockquote class="twitter-tweet"><p lang="en" dir="ltr">When will polar bear populations collapse?

<p>But the study, published in <a href="https://www.nature.com/articles/s41558-020-0818-9" target="_blank"><em>Nature Climate Change</em></a> Monday, is the first to predict when and where Arctic warming will threaten the bears' survival, <a href="https://www.theguardian.com/environment/2020/jul/20/most-polar-bears-to-disappear-by-2100-study-predicts-aoe" target="_blank">The Guardian reported</a>.</p><p>"It's been clear for some time that polar bears are going to suffer under climate change," Molnár told The Guardian. "But what was not fully clear was when we would expect major declines in the survival and reproduction of polar bears that could ultimately lead to their extirpation."</p><p>To answer this question, scientists looked at two emissions scenarios: business as usual and a more moderate option in which emissions peak in 2040 before starting to fall, according to <a href="https://www.nytimes.com/2020/07/20/climate/polar-bear-extinction.html" target="_blank">The New York Times</a>. Under the business-as-usual model, all populations of polar bears would be wiped out by 2100, except for the bears living in Canada's northernmost Queen Elizabeth Islands, The Guardian reported. But even under the moderate scenario, most populations were likely to suffer reproductive failure by 2080, the study found.</p>
<blockquote class="twitter-tweet"><p lang="en" dir="ltr">For the first time, scientists have answered the critical question of 'when' the persistence of polar bear populations across the Arctic will be threatened due to sea ice loss from global warming.<a href="https://t.co/NW2vf3QbPx">https://t.co/NW2vf3QbPx</a> <a href="https://twitter.com/nresearchnews?ref_src=twsrc%5Etfw">@nresearchnews</a> <a href="https://twitter.com/hashtag/climateactionnow?src=hash&ref_src=twsrc%5Etfw">#climateactionnow</a> <a href="https://t.co/6c8V2nYhzy">pic.twitter.com/6c8V2nYhzy</a></p>— Polar Bears International (@PolarBears) <a href="https://twitter.com/PolarBears/status/1285333085031141377?ref_src=twsrc%5Etfw">July 20, 2020</a></blockquote> <script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script>
<p>"The study shows clearly that polar bears are going to do better with less warming," University of Alberta polar bear expert Andrew Derocher, who was not involved with the study, told The New York Times. "But no matter which scenario you look at, there are serious concerns about <a href="https://www.ecowatch.com/tag/conservation" target="_self">conservation</a> of the species."</p><p>Polar bears can fast for months at a time when sea ice melts in the spring and summer. The researchers made their predictions based on how long male bears could reasonably fast and survive and how long females could reasonably fast and raise their young compared with how long different parts of the Arctic are projected to be ice free through 2100.</p><p>They assessed 13 of 19 polar bear populations, or around 80 percent of the roughly 25,000 bears remaining. Bears in Canada's Archipelago ecoregion were not assessed because it is hard to estimate future sea ice in the area's islands and channels, according to The Guardian.</p>
<p>If nothing is done to reduce emissions, bears in Canada's southern Hudson Bay and Davis Strait could fail to reproduce by 2040 while most bears in Alaska and Russia could be at risk by 2080. The polar bear population in western Hudson Bay has already shrunk around 30 percent since 1987.</p><p>"Showing how imminent the threat is for different polar bear populations is another reminder that we must act now to head off the worst of future problems faced by us all," study coauthor and chief scientist of <a href="https://polarbearsinternational.org/" target="_blank">Polar Bears International</a> Dr. Steven Amstrup told BBC News. "The trajectory we're on now is not a good one, but if society gets its act together, we have time to save polar bears. And if we do, we will benefit the rest of life on Earth, including ourselves."</p>

Jane Goodall on Conservation, Climate Change and COVID-19: 'If We Carry on With Business as Usual, We're Going to Destroy Ourselves'

Dr. Jane Goodall, the world-renowned conservationist, desperately wants the world to pay attention to what she sees as the greatest threat to humanity's existence. Craig Barritt / Getty Images for TIME
By Jeff Berardelli
While COVID-19 and protests for racial justice command the world's collective attention, ecological destruction, species extinction and climate change continue unabated. While the world's been focused on other crises, an alarming study was released warning that species extinction is now progressing so fast that the consequences of "biological annihilation" may soon be "unimaginable."
<p><a href="https://www.janegoodall.org/" target="_blank">Dr. Jane Goodall</a>, the world-renowned conservationist, desperately wants the world to pay attention to what she sees as the greatest threat to humanity's existence.</p><p>CBS News recently spoke to Goodall over a video conference call and asked her questions about the state of our planet. Her soft-spoken grace somehow helped cushion what was otherwise extremely sobering news: "I just know that if we carry on with business as usual, we're going to destroy ourselves. It would be the end of us, as well as life on Earth as we know it," warned Goodall.</p><p>What follows is a lightly edited transcript of our conversation.<br> </p>
<p><strong><em>Jeff Berardelli:</em></strong> <strong>Destruction of nature is causing some really big concerns around the world. One that comes to the forefront right now is </strong><a href="https://www.cbsnews.com/news/coronavirus-environment-pandemic-infectious-diseases/" target="_blank"><strong>emergent diseases like COVID-19</strong></a><strong>. Can you describe how destruction of the environment contributes to this?</strong></p><p><strong></strong><strong><em>Dr. Jane Goodall:</em></strong> Well, the thing is, we brought this on ourselves because the scientists that have been studying these so-called zoonotic diseases that jump from an animal to a human have been predicting something like this for so long. As we chop down at stake <span style="background-color: initial;"><a href="https://www.cbsnews.com/news/coronavirus-brazil-amazon-rainforest-destruction/" target="_blank">tropical rainforest</a></span>, with its rich biodiversity, we are eating away the habitats of millions of animals, and many of them are being pushed into greater contact with humans. We're driving deeper and deeper, making roads throughout the habitat, which again brings people and animals in contact with each other. People are hunting the animals and <span style="background-color: initial;"><a href="https://www.cbsnews.com/news/wuhan-china-coronavirus-bans-eating-wild-animals-breeding-wet-markets/" target="_blank">selling the meat</a></span>, or trafficking the infants, and all of this is creating environments which are perfect for a virus or a bacteria to cross that species barrier and sometimes, like COVID-19, it becomes very contagious and we're suffering from it.</p><p>But we know if we don't stop destroying the environment and disrespecting animals — we're hunting them, killing them, eating them; killing and eating chimpanzees in Central Africa led to HIV/AIDS — there will be another one. It's inevitable.</p><p><strong>Do you fear that the next [pandemic] will be a lot worse than this one?</strong></p><p>Well, we've been lucky with this one because, although it's incredibly infectious, the percentage of people who die is relatively low. Mostly they recover and hopefully then build up some immunity. But supposing the next one is just as contagious and has a percentage of deaths like <a href="https://www.who.int/news-room/fact-sheets/detail/ebola-virus-disease" target="_blank">Ebola</a>, for example, this would have an even more devastating effect on humanity than this one.</p>
<p><strong>I think people have a hard time connecting these, what may look like chance events, with our interactions and relationship with nature. Can you describe to people why the way that we treat the natural world is so important?</strong><br></p><p>Well, first of all, it's not just leading to zoonotic diseases, and there are many of them. The destruction of the environment is also contributing to the <a href="https://www.cbsnews.com/climate-change/" target="_blank">climate crisis</a>, which tends to be put in second place because of our panic about the pandemic. We will get through the pandemic like we got through World War II, World War I, and the horrors following the World Trade towers being destroyed. But climate change is a very real existential threat to humankind and we don't have that long to slow it down. </p><p>Intensive farming, where we're destroying the land slowly with the chemical poisons, and the monocultures — which can be wiped out by a disease because there is no variation of crops being grown — is leading to habitat destruction. It's leading to the creation of more <span style="background-color: initial;"><a href="https://www.cbsnews.com/news/coronavirus-lockdowns-climate-change-carbon-dioxide-emissions/" target="_blank">CO2</a></span> through fossil fuels, methane gas and other greenhouse gas [released] by digestion from the billions of domestic animals.</p><p>It's pretty grim. We need to realize we're part of the environment, that we need the natural world. We depend on it. We can't go on destroying. We've got to somehow understand that we're not separated from it, we are all intertwined. Harm nature, harm ourselves.</p><p><strong>If we continue on with business as usual, what do you fear the outcome will be?</strong></p><p>Well, if we continue with business as usual, we're going to come to the point of no return. At a certain point the ecosystems of the world will just give up and collapse and that's the end of us eventually too.</p><p>What about our children? We're still bringing children into the world — what a grim future is theirs to look forward to. It's pretty shocking but my hope is, <a href="https://www.cbsnews.com/news/earth-day-how-the-pandemic-is-changing-air-pollution-levels/" target="_blank">during this pandemic</a>, with people trapped inside, factories closed down temporarily, and people not driving, it has <a href="https://www.cbsnews.com/news/coronavirus-photos-decline-air-pollution-lockdown/" target="_blank">cleared up the atmosphere</a> amazingly. The people in the big cities can look up at the night sky and sea stars are bright, not looking through a layer of pollution. So when people emerge [from the pandemic] they're not going to want to go back to the old polluted days.</p><p>Now, in some countries there's not much they can do about it. But if enough of them, a groundswell becomes bigger and bigger and bigger [and] people say: "No I don't want to go down this road. We want to find a different, green economy. We don't want to always put economic development ahead of protecting the environment. We care about the future. We care about the health of the planet. We need nature," maybe in the end the big guys will have to listen.</p>
<p><strong>I often think our economic future, which is always put at the forefront, is actually dependent upon our ecological future. Without an ecological future, there is not going to be any economic growth. Would you agree?</strong></p><p>Absolutely. I mean, it's all been said again and again, but fossil fuels are not infinite, they will come to an end, leading to a lot more destruction of the environment for sure. Forests and natural resources are not infinite and yet we're treating them as though they are, and in some places using them up more quickly than nature can replenish them.</p>We have to have a <span style="background-color: initial; font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;"><a href="https://www.cbsnews.com/news/climate-change-action-economic-benefit-study-finds/" target="_blank">different kind of economy</a></span>, we need a different way of thinking about what is success.<strong> </strong>Is it just about having more and more money, more and more stuff, being able to show off to your friends, and the wasteful society we live in? We waste <span style="background-color: initial; font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;"><a href="https://www.cbsnews.com/news/earth-day-2019-fashion-industrys-carbon-impact-is-bigger-than-airline-industrys/" target="_blank">clothes</a></span>, we waste <span style="background-color: initial; font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;"><a href="https://www.cbsnews.com/news/americans-waste-nearly-a-pound-of-food-each-per-day-study-finds/" target="_blank">food,</a></span> we waste laptops and cellphones. That pollutes the environment. So we've got to think differently, haven't we?<p><strong>So what do we do? Right now our worldview is based on GDP. You suggest that we think of it in a different way. So do you have a suggestion of how we rate our success other than GDP?</strong></p><p>I'm not an economist.<strong> </strong>I just know that if we carry on with business as usual, we're going to <a href="https://www.cbsnews.com/news/new-climate-change-report-human-civilization-at-risk-extinction-by-2050-new-australian-climate/" target="_blank">destroy ourselves</a>. It would be the end of us, as well as life on Earth as we know it.</p><p>So one thing we can do, those of us in affluent societies can almost all do with a bit less. We have a very unsustainable lifestyle. You can't really blame people, they grew up into it. But if you went through World War II like I did, when you took nothing for granted, one square of chocolate for a week is what we had and everything was rationed. So, you appreciate it. We never wasted even an ounce of food; not like today. </p><p>Then, we also have to alleviate poverty. Because if you're really poor you destroy the environment, you cut down the last trees to make land to grow more food for your family, or fish the last fish. Or if you're in an urban area you buy the cheapest junk food. You don't have the luxury of asking: how is this made, did it harm the environment, did it lead to the suffering of animals like in the factory farms, is it cheap because of child slave labor? You just have to buy the cheapest in order to survive. </p><p>Then the third thing, which nobody wants to talk about, but nevertheless ... there are approximately 7.8 billion of us on the planet today and already in some places we're using up natural resources faster than nature can replenish them. In 2050 it's estimated that there will be 9.7 billion of us. What will happen? We can't just go on burying it under the carpet. </p><p>Population issues are politically sensitive so I talk about voluntary population optimization. So that's OK, it's voluntary, it is your choice. You optimize it for your financial situation. People are desperate to educate their children and they can't educate eight anymore. So they love family planning, and women can space out their children so that they can have a child and look after it.</p>
<p><strong>Let's switch gears. I don't eat animals. I have a dog. I love my dog. Let's talk about the idea that animals have feelings and that pigs are as intelligent as dogs...</strong></p><p>You know, animals are so much more intelligent than people used to think, and they have feelings and emotions and personalities, like your dog, any animal you share your life with. You know, birds now are making tools and octopus are incredibly intelligent. And when we think of all this trafficking of animals, selling them in meat markets or factory farms, when you think that each one one is an individual, can feel fear and pain, can suffer mentally as well as physically, isn't it shocking? I'm glad you don't eat them. I don't either, of course. </p><p>The shock and horror because in China and South Korea they <span style="background-color: initial;"><a href="https://www.cbsnews.com/news/dog-meat-festival-china-underway-in-yulin-but-activists-hope-it-will-be-the-last-amid-coronavirus/" target="_blank">eat dogs</a></span> — well, the thought of eating a dog makes me feel particularly sick, but not more sick than eating a pig. They eat dogs and we don't like it, but we eat pigs, and they are as intelligent as dogs.</p><p>Isn't the point, if you must eat an animal shouldn't you treat it really well, like the Native Americans, respect the animal and give thanks that it's sacrificed itself for you?</p><p><strong>This is a bit more of a thought-provoking question: What has led us to this over-consumption in society? There is an idea that perhaps there is a Biblical basis, that we have dominion, that we're in charge, and because we're in charge we're able to do what we want. Can you give me an idea of why we are where we are, as a world right now, and what led us here? </strong></p><p>[Laughing]<strong> </strong>You think I'm going to be able to answer all these questions?</p><p><strong>I know it's a lot, but I know that you must have some thoughts on this.</strong></p><p><strong></strong>Well, first of all, I do think that religion has played a role. I was told by a Hebrew scholar the original translation of that word that you just mentioned, "dominion," is wrong. It's actually something more like "stewardship." That's very different. If God gave us stewardship that's different from saying we have dominion. So I think religion started this thinking that we're so different from all the other animals and I was taught there was a difference in kind, not degree. Thank goodness the chimpanzees are so like us biologically, as well as behaviorally, that science had to start thinking differently.</p><p>So how did we get there? It's sort of been like this all throughout human history. There were so many fewer of us back then that we could have these unsustainable lifestyles and it didn't really matter; they were sustainable. Think of how people have always exploited the natural world just because we can. And so there's been a lag between developing new technologies [which enable us to] destroy whole forests. Whereas the indigenous people might take a week to cut down the big tree, we can do it in an hour. And the moral evolution and the sense of a spiritual awareness and connection to the natural world on which we depend, that's lagged behind as well.</p>
<p><strong>So how do we repair that? How do we rediscover our connection to the rest of the natural world?</strong></p><p>As I think you know, I began a program for young people back in 1991 called <a href="https://www.rootsandshoots.org/" target="_blank">Roots and Shoots</a> because young people had lost hope in the future. I've met them all over the world. They were mostly apathetic and didn't seem to care. Or they were angry or deeply depressed and they told me they felt like that because we compromised their future and there was nothing they could do about it. And we have compromised their future. We've been stealing it for years and years. And yes, we still are still stealing it today. But when they said there was nothing they could do I thought, no, that's not right. We got this window of time. If we all get together, take action, we can start healing some of the harm, we can start slowing down climate change and we can work on educating people. </p><p>Kids are really good at educating their parents and grandparents, some of whom may be in positions to make a huge difference, like CEOs of big companies or people in government. That program is now kindergarten to university and everything in between. It's in 68 countries and growing. Every group has the message: Each one of us — and that means you as well as me — we make some impact every single day and we have the luxury of choosing the impact that we make.</p>

Amazon river dolphins are classified as endangered by the International Union for Conservation of Nature. Sylvain CORDIER / Gamma-Rapho / Getty Images
By Peter Yeung
A pair of pink Amazon river dolphins emerges for just a moment, arcing above the chocolate brown waters inside the Mamirauá Institute for Sustainable Development, a research facility at the tropical heart of the Brazilian Amazon. Powerful jets of water spray out of their blowholes as these freshwater mammals take in air before submerging.
<p>Moments later the duo reappear on the other side of the Japurá River, playfully dovetailing, and skirting the edge of the <em>várzea</em> rainforest — a seasonal floodplain where, in this part of Amazonia, river levels can rise and fall by up to 12 meters (39 feet) a year, at times opening up vast swathes of rainforest to these graceful swimmers.</p><p>"They are very special creatures," says Natanael dos Santos, a guide working at the Mamirauá Institute. "They are extremely intelligent and can display a complex set of behaviors, even like humans." These skilled, sharp-toothed hunters, often reaching more than eight feet in length, are well adapted to shifting river levels. During highwater periods they penetrate deep into the rainforest using echolocation to search murky pools amid submerged tree roots for prey including dozens of fish species, turtles and freshwater crabs.</p><p>The Amazon river dolphin (<em>Inia geoffrensis</em>) or boto, already <a href="https://www.iucnredlist.org/species/10831/50358152" target="_blank">classified as "endangered"</a> since 2018 by the IUCN, the International Union for Conservation of Nature, is now coming under even more serious threat across Brazil and Latin America. An estimated population in the <a href="https://www.worldwildlife.org/species/amazon-river-dolphin" target="_blank">low tens of thousands</a> is thought to exist in the wild, though counting the animals accurately in the Amazon's murky streams is challenging. Like other river dolphins, the boto communicates with variable whistle tones.</p><p>Occupying the Amazon and Orinoco river basins, which cut across the northern half of the South American continent, these freshwater mammals were historically abundant, and are protected today by Brazilian law; it is illegal to kill them. But for years, poachers have <a href="https://www.researchgate.net/publication/261359911_Insights_on_the_use_of_dolphins_boto_Inia_geoffrensis_and_tucuxi_Sotalia_fluviatilis_for_bait_in_the_piracatinga_Calophysus_macropterus_fishery_in_the_Western_Brazilian_Amazon" target="_blank">targeted the dolphins</a>, using their fatty blubber as bait to catch a carnivorous catfish called <em>piracatinga</em>, which is drawn to the scent of rotting flesh.</p>
<p>In January 2015, under the government of Brazilian President Dilma Rousseff, that chronic criminal behavior led to the introduction of a <a href="https://infoamazonia.org/pt/2015/03/amazon-fishermen-want-to-reduce-time-of-moratorium-on-piracatinga-fish/#!/story=post-12510&loc=-4.389559200000014,-64.55674760000001,7" target="_blank">five-year moratorium</a> on catching <em>piracatinga</em> in order to better protect the dolphins.</p><p>But that moratorium ended earlier this year and has yet to be renewed by the Jair Bolsonaro administration, which is undermining many other of Brazil's environmental laws. Experts warn that the failure to extend it could lead to the extinction of the largest freshwater dolphin in the world — a fate that befell <a href="https://www.theguardian.com/environment/2007/aug/08/endangeredspecies.conservation" target="_blank">China's Yangtze river dolphin (</a><a href="https://www.theguardian.com/environment/2007/aug/08/endangeredspecies.conservation" target="_blank"><em>Lipotes vexillifer</em></a><a href="https://www.theguardian.com/environment/2007/aug/08/endangeredspecies.conservation" target="_blank"><em>)</em></a> in 2007, following years of overfishing, pollution and habitat degradation.</p><p>"I believe [the lack of a moratorium] could make them extinct," warns Dr. Vera da Silva, a researcher for INPA, the Amazon research institute, who has been studying Amazonia's dolphins for more than 30 years. "Not all the objectives of the moratorium were fulfilled, therefore the moratorium must be extended," she explained.</p><p>Research by da Silva, <a href="https://academic.oup.com/biolinnean/article-abstract/123/3/666/4888610" target="_blank">published in 2017</a>, found that a female dolphin's pregnancy typically lasts 13 months. After that, the mother feeds a calf underwater for two years. Due to that long gestation and nursing period, females only reproduce every three to five years.</p><p>"They are a very slow reproductive species," da Silva notes. "If the removal is higher [than the reproduction and rearing rate] the species does not have the capacity to replace itself."</p><p>Separate <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0191304" target="_blank">findings</a> by da Silva published in 2018 revealed that the Amazon river dolphin population in Brazil is halving every decade.</p>
<p>Prosecutors in Amazonas state, where the Mamirauá Institute is based, originally asked for the moratorium which started in 2015, warning that as many as 2,500 dolphins were being killed illegally each year for bait.</p><p>Da Silva reports that in November 2019 she met with officials from the Secretariat of Production of the State of Amazonas (SEPROR), to discuss the extension of the moratorium in Amazonas. But nothing has happened since, and the peak fishing season is due to begin in July.</p><p>"There is a huge amount of ignorance," she warns. "We need better information on fishing practices. There aren't strong enough laws to make fishermen report what they catch."</p><p>Marcelo Oliveira, a conservation specialist at World Wildlife Fund Brazil (WWF), agrees with that analysis. "Fishing is a threat but we don't have enough data," he says. "If we don't know where the river dolphins are, we can't say how bad [the threat] is. But it's expensive to do expeditions to monitor population trends."</p><p>WWF has been innovating — utilizing drones to accomplish the difficult job of making improved population estimates, flying 2.5 kilometer strips of river to record footage. "It's much cheaper and more efficient," than doing boat observations, he says. The NGO is currently partnering with British universities to analyze the drone findings using artificial intelligence.</p><p><span></span>But even with better data recording practices and an improved data set, Oliveira says that the river dolphins are still at great risk from a broad range of threats. "Bycatch sees so many dolphins caught in fishing nets, gold mining in the region has led to mercury poisoning in the water, and the construction of hydroelectric dams has reduced their habitat and genetic pool," he explains.</p>
<p>Oliveira believes that for now the focus of dolphin conservation should be on improved community engagement across the Amazon basin, with strong outreach to fishermen, in a region whose burgeoning population has now topped 34 million.</p><p>"Extending the moratorium could be a way to protect the dolphins, alternative baits could be a way, but we need to have a balance between development and biodiversity conservation," he says. "It's not a fight between the two. If communities are involved in conservation, the dolphins will be safer."</p><p>Fernando Trujillo, scientific director of the <a href="https://omacha.org/" target="_blank">Fundacion Omacha</a>, a Colombia-based environmental NGO specializing in protecting river dolphins set up in 1993, says that conservation must also be addressed on an international level.</p><p>"The end of [Brazil's] moratorium will send out the message that fishing is okay — even in other countries across Latin America," he says. "We need to work together with all the countries in terms of policy, agreeing on the same criteria and same legislation, especially when it comes to monitoring the borders."</p><p>Trujillo, who is also co-chair of the International Whaling Commission's small cetaceans committee, is calling for the Brazil moratorium to be extended another five years. "For so many reasons, it's a species we need to conserve and save," he says. "Alive dolphins can produce more money than dead ones for local communities through ecotourism."</p>
<p>Indigenous beliefs hold that the river dolphin — which transforms from grey to pink as it ages — is a magical creature. Males and females are both said to have the ability to morph at will into either a handsome man, or beautiful woman respectively, in order to seduce villagers in the dark of night. But scientists see the mammals as top predators of the Amazon aquatic ecosystem — considering them the jaguars of the rivers.</p><p>A spokesperson for the Ministry of Agriculture, Livestock and Supply said it had not yet extended the moratorium because "it is necessary to evaluate its effects on the recovery of populations of porpoises and caimans in order to verify the effectiveness of this fisheries management measure." When asked by Mongabay to comment, the ministry did not provide a timeframe for this evaluation period.</p><p>There is another myth about the Amazon river dolphin. It is said that to kill one is bad luck. Not knowing what negative aquatic impacts might radiate from the extinction of this top predator, authorities may want to heed this legend as they try to decide whether or not to renew Brazil's moratorium.</p>

The sixth mass extinction is here, and it's speeding up.
<p>A new study, <a href="https://www.pnas.org/content/early/2020/05/27/1922686117" target="_blank">published in the Proceedings of the National Academy of Sciences Monday</a>, found that 515 land <a href="https://www.ecowatch.com/animals/" target="_self">animals</a> are currently on the brink of extinction. That's slightly less than the at least 543 species that disappeared last century. However, these extremely <a href="https://www.ecowatch.com/tag/endangered-species" target="_self">endangered species</a> are expected to disappear in the next two decades, <a href="https://news.stanford.edu/press/view/34340" target="_blank">Stanford University explained in a press release</a>.</p><p>"When humanity exterminates populations and species of other creatures, it is sawing off the limb on which it is sitting, destroying working parts of our own life-support system," study coauthor and Stanford University biologist Paul Ehrlich said in the press release. "The <a href="https://www.ecowatch.com/tag/conservation" target="_self">conservation</a> of endangered species should be elevated to a national and global emergency for governments and institutions, equal to <a href="https://www.ecowatch.com/climate-change/" target="_self">climate</a> disruption to which it is linked."</p>
<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="8768fc2a38d4601fb0f3f9fbfae1718c"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/vES3YlXcrrc?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span>
<p>Ehrlich helped to write a 2015 study confirming that a sixth mass extinction had begun, and he now says the extinction rate is likely higher than previously thought. Species are going extinct at rates hundreds or thousands of times faster than the "background" rate for the last tens of millions of years, and are being killed off by one overriding factor: us. Several specific human actions are behind these losses, including habitat loss, hunting, the introduction of invasive species, pollution, the <a href="https://www.ecowatch.com/tag/wildlife" target="_self">wildlife</a> trade and the climate crisis.</p><p>"The massive losses that we are experiencing are being caused, directly or indirectly, by the activities of <em>Homo sapiens,</em>" the study authors wrote.</p>
<p>To draw their conclusions, the researchers looked at data on 29,400 land vertebrate species compiled by the <a href="https://www.iucnredlist.org/" target="_blank">IUCN Red List of Threatened Species</a> and <a href="https://www.birdlife.org/" target="_blank">BirdLife International</a>, <a href="https://www.theguardian.com/environment/2020/jun/01/sixth-mass-extinction-of-wildlife-accelerating-scientists-warn?CMP=twt_a-environment_b-gdneco" target="_blank">The Guardian explained</a>. Of those species, 515 had populations of fewer than 1,000, and about half of the 515 were down to less than 250 individuals.</p><p>Most of the at-risk species live in the tropics or subtropics. They include the Sumatran rhino, the Clarión wren, the Española giant tortoise and the harlequin frog.</p>

Terrestrial vertebrates on the brink (i.e., with 1,000 or fewer individuals) include species such as (A) Sumatran rhino (Dicerorhinus sumatrensis; image credit: Rhett A. Butler [photographer]), (B) Clarion island wren (Troglodytes tanneri; image credit: Claudio Contreras Koob [photographer]), (C) Española Giant Tortoise (Chelonoidis hoodensis; image credit: G.C.), and (D) Harlequin frog (Atelopus varius; the population size of the species is unknown but it is estimated at less than 1,000; image credit: G.C.).
<p>Because ecosystems are so interconnected, the disappearance of any of these at-risk species would put other species at risk. For example, when sea otters were overhunted in the Bering Sea, the population of sea urchins bloomed, devouring kelp forests and driving the Steller's sea cow to extinction. Eighty-four percent of species with populations under 5,000 live in the same regions as species with populations under 1,000, making such a domino effect more likely.</p><p>"Extinction breeds extinction," the researchers wrote.</p>
<p>The eradication of <a href="https://www.ecowatch.com/tag/biodiversity" target="_self">biodiversity</a> is also a major threat to human civilization. The most timely example is the spread of the new <a href="https://www.ecowatch.com/tag/coronavirus" target="_self">coronavirus</a>, which originated in bats and is believed to have passed to humans through another animal at a wildlife market, the press release explained.</p><p>"Based on our research and what we're seeing, the extinction crisis is so bad that whatever we do in the next 10 to 50 years is what will define the future of humanity," study coauthor professor Gerardo Ceballos of the National University of Mexico in Mexico City told <a href="https://www.bbc.co.uk/news/science-environment-52881831" target="_blank">BBC News</a>.</p><p>The researchers called for a ban on the international wildlife trade, according to Stanford. They have also started an initiative called <a href="https://stopextinctions.org/" target="_blank">Stop Extinction</a> to raise awareness of the biodiversity crisis.</p><p>"In view of the current extinction crisis and the lack of widespread actions to halt it, it is very important that scientists should metaphorically take to the streets," they wrote.</p>

The Ebo Forest in Cameroon, Africa, is a biodiversity hotspot, home to an amazing range of wildlife, including forest elephants, gorillas, drills, chimpanzees, grey parrots and the goliath frog. San Diego Zoo Global
By Lamfu Fabrice Yengong and Sylvie Djacbou Deugoue
Biodiversity loss is a global crisis. In May last year, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) warned that over 1,000,000 species are threatened with extinction worldwide. On May 22, the International Day of Biodiversity, it is important to recall the silent victims of our country's obsession for industrial growth at the expense of our forests.
<p>Tropical rainforests are estimated to harbor more than half of the world's plant and animal species. They are also essential for access to water, regulating temperature and preventing soil erosion. It's time to return the forests to indigenous and local communities. </p><p>In our country, Cameroon, the conservation of biodiversity, global climate goals and human rights of indigenous and local communities are all put at stake for industrial exploitation of the rainforest, driven by short-sighted thinking. Biodiversity hotspots are put at risk by industrial logging and agriculture, as trees are cut for the tropical timber market and entire forests cleared to make room for oil palm and rubber plantations. The government tries to assure conservationists that some space will be reserved for the wildlife in the forest it trashes, but even protected areas are not truly safe. </p><p>Companies, usually foreign-owned, are rapidly destroying rainforests that have existed for years. Local communities are left poorer after their traditional source of livelihood is desecrated. The only ones getting rich are a small group of beneficiaries that are close to the circles of power. </p><p>Some low-income countries that are rich in forests are resorting to quick solutions like logging and industrial agriculture. But industrial logging concessions and rubber and palm oil plantations are never the job-creating mechanism they promise to be. That has been demonstrated over and over again in forest countries around the world.</p>
<p>For example, <a href="https://whc.unesco.org/en/list/407/" target="_blank">the Dja Faunal Reserve</a>, a UNESCO world heritage site in the South of Cameroon, is home to more than 100 species of mammals, including at least 14 primates, such as the endangered western lowland gorilla, chimpanzee, and white-collared mangabey, as well as species such as the endangered forest elephant, and the African grey parrot, bongo antelope and leopard.</p><p>The Dja Faunal Reserve is adjacent to the Sudcam rubber plantation, mainly owned by rubber giant Halcyon Agri. Sudcam has cleared more than 10,000 hectares (approximately 25,000 acres) of dense tropical rainforest in the South region of Cameroon – an equivalent of 10 football pitches a day – to make way for a rubber plantation between 2011 and 2018. The rubber plantation has rattled the lives of several indigenous communities, namely the Baka, but it has also aggravated the lives of those numerous protected species in the Dja Reserve.</p><p>To indigenous and local forest dependent communities, the rainforest serves as a source of nutritious foods and traditional medicine, much of which science has yet to explore. The forest is also the foundation of their social life, from recreational to ritual practices. Furthermore, biodiversity loss itself is a direct and immediate threat to the livelihood of indigenous peoples like the Baka next to the Sudcam plantation.</p><p>Upon the arrival of rubber company Sudcam, the indigenous community has lost access to its forest and specifically to the animals and plants they rely on. As Sudcam gets richer, it leaves entire communities in impoverishment, abjectness and destitution. </p>
<p>That is the fate which the chiefs of the Banen people of the Littoral region in Cameroon are trying to avoid <a href="http://www.cameroon-info.net/article/cameroun-denonciation-le-peuple-banen-du-littoral-soppose-a-la-confiscation-de-ses-terres-371484.html" target="_blank">in their current struggle</a> against the destruction of large parts of the Ebo forest. </p><p>The <a href="https://www.globalwildlife.org/blog/ebo-forest-a-stronghold-for-cameroons-wildlife/" target="_blank">Ebo Forest</a> is a biodiversity hotspot, one of the intact forest ecosystems in the Gulf of Guinea, stretching over 2000 square kilometers (approximately 772 square miles). Ebo Forest is home to an amazing range of wildlife, including forest elephants, gorillas, drills, chimpanzees, grey parrots and the goliath frog – the largest living frog on the planet. Accordingly, it was designated over a decade ago by the Cameroon Government as a National Park. </p><p>However, on February 4, the same government of Cameroon authorized two logging concessions (<a href="https://drive.google.com/file/d/1P8O3pc1JeLaAnDF1ERXvRrIAzjnw09SG/view" target="_blank">UFA07005</a> and <a href="https://drive.google.com/file/d/1n2cgvavirDdYmApiTd5vLV0hQRova6Ed/view" target="_blank">UFA07006</a>) inside the area of Ebo Forest. The planned concessions are enormous – about the size of London. Again, the government of Cameroon wants to convince us that conservation can be done with chainsaws. </p><p>Biodiversity loss doesn't only mean our children would get to see some of the world's most marvelous creatures only in documentary films. The consequences are far greater and more tangible.</p>
<p>The extinction of forest elephants, for example, small relatives of African Savanna elephants, might also reduce the number of large trees that they support, trees that excel at storing carbon. In the Congo Basin forest, the disappearance of forest elephants might mean a loss of about three billion tons of carbon – equivalent to France's CO2 emissions over more than 25 years, according to a <a href="https://www.nytimes.com/2019/08/19/science/elephants-climate-change.html" target="_blank">New York Times article</a> on recent research published in the journal <em>Nature Geoscience.</em> </p><p>Cameroon's government has made public commitments to preserve and protect biodiversity. Positive declarations and ambitious plans may win applause and some international funding, but all eyes should be on implementation. <a href="https://www.greenpeace.org/africa/en/press/8593/we-were-told-not-to-go-into-the-forest-anymore-greenpeace-investigation-exposes-human-rights-violations-by-halcyon-agri/" target="_blank">Field investigations by Greenpeace Africa</a> and others clearly show how far we are from protecting biodiversity. </p><p>In Cameroon's government, as well as in the meeting rooms and corridors of development agencies, decision makers often hold outdated views. Too often we hear that only through rapid and massive removal of the rainforest in favor of large-scale logging and industrial agriculture plantations can the country emerge out of poverty. </p><p>Yet that model has repeatedly failed the people, as short-term high profits always remained accessible only to a small circle of beneficiaries. On the contrary, local communities who have lived in harmony with nature for many generations are likely to face poverty, abuse, hunger and alcoholism <a href="https://www.scientificamerican.com/article/how-sustainable-development-ravaged-the-congo-basin/" target="_blank">wherever</a> forests are suddenly destroyed. It is becoming increasingly clear that the best solution for both human rights and the planet is for forests to be managed by local communities. They do so much better than the industrial loggers or plantation owners. </p>
<p>The Cameroonian government needs to realize that trashing forests is not the way to make the economy grow. Rapid and intensive exploitation of nature has more far-reaching consequences than short-term economic growth. To prevent the extinction of fauna and flora species, indigenous communities that live among them need the rights to manage their forest.</p>
<p>Standing for biodiversity means communities should get the rights to manage their forests, instead of the corporations that destroy them. </p>

A view of the Piton de la Fournaise crater. Malavika Vyawahare
By Malavika Vyawahare
Giant tortoises and flying foxes once roamed La Réunion, a volcanic island off the eastern coast of Africa. Then humans arrived and decided to stay. Within 150 years of their appearance, large fruit-eating animals like the giant tortoises (Cylindraspis indica) and flying foxes (Pteropus niger), a type of bat, were wiped off the face of La Réunion.
<p>This speck of land in the western Indian Ocean, an overseas department of France, was one of the last corners of the planet to be colonized by humans. It is also home to the Piton de la Fournaise, one of the most active volcanoes in the world. It was recently in the throes of another eruption, having erupted almost 240 times since 1650.</p><p>The scars from these eruptions are <u><a href="https://besjournals.onlinelibrary.wiley.com/doi/abs/10.1111/1365-2745.13359" target="_blank">now helping scientists uncover</a></u> the lasting effects of permanent human settlement on life on the island, including the loss of large-fruited trees like <em>Sideroxylon borbonicum</em>, known locally as <em>bois de fer de Bourbon</em>, and <em>Labourdonnaisia calophylloides</em>, or <em>bois de natte à petites feuilles</em>.</p><p>The fates of flora and fauna are linked. Animals and birds are important to plants; they help to disperse seeds, transporting them near and far. Which seeds and how far they get scattered depend on the kind of creatures that get their paws or beaks on the seeds. The largest fruit eater inhabiting the island today is the Réunion bulbul (<em>Hypsipetes borbonicus</em>), a bird a thousand times smaller than the now extinct giant tortoise. The bulbul can't feed on fruits that the tortoise could eat.</p><p>Not many would consider living in the shadow of an active volcano good fortune. For Sébastien Albert and his colleagues at the University of La Réunion, however, the frequency of eruptions at Piton de la Fournaise has proven providential. They recently published a paper in the <em>Journal of Ecology</em> describing the loss of large-fruited trees by creating a timeline over several centuries. Because the time of each eruption is known, it is possible to see how the plant community changed before and after human colonization.</p>
<p>Albert described the island as a "paradise" before humans established themselves there around the mid-17th century. The forests were dotted with towering trees that bore large, fleshy fruits enclosing chunky seeds. Seeds come in all sizes; the biggest in the world is the genitalia-shaped seed of the coco de mer (<em>Lodoicea maldivica</em>) found on Seychelles, an archipelago north of La Réunion. It can grow 30 centimeters (1 foot) across and weigh more than 15 kilograms (33 pounds). At the other end of the spectrum, some orchids produce seeds that are a fraction of a millimeter across, finer than a grain of sand.</p><p>The Réunion bulbul can only consume seeds smaller than 13 mm, or about half an inch. A larger species of bird native to La Réunion, the Mascarene parrot (<em>Mascarinus mascarin</em>), went extinct before the turn of the 19th century. So did the Réunion fruit pigeon (<em>Nesoenas duboisi</em>).</p><p>Throughout the Mascarenes — the Indian Ocean islands of Mauritius, Rodrigues (which is today part of Mauritius), and La Réunion — this is a familiar tale. The extinction of the dodo (<em>Raphus cucullatus</em>) in Mauritius is emblematic of creatures lost to human exploitation.</p>
<p>Overhunting, habitat loss and invasive predators contributed to the animals' disappearance. Giant tortoises were hunted by European sailors for their meat even before human habitation began. Their eggs fell prey to invasive species like pigs, cats and rats. Henri du Quesne, a French naval officer, wrote of the tortoises: "Their Flesh is very delicate; the Fat better than Butter or the best Oil, for all sorts of Sawces." Another account from 1671 noted that it was not possible to go six steps without coming upon one of these friendly giants. By 1800, they were all but gone.</p><p>The difficult part is linking their disappearance to impacts on tree diversity. "There is evidence for declines in large-seeded species that rely on large vertebrates for the dispersal of their seeds. Examples include Africa, Peru, and Brazil," said Elizabeth Wandrag, a plant ecologist at the University of New England, Australia, who was not involved in the study.</p><p>"It is not always possible to explicitly link the loss of large frugivores, and wholesale losses of species — many tree species that rely on large frugivores for dispersal are still present in forests that have lost those dispersers but have instead become more aggregated and/or show lower survival," Wandrag told Mongabay in an email.</p>
<p>Which is where the lava flows come in. Lava flow from a volcanic eruption is a major disturbance for any ecosystem; it tears through forests, burning everything in its path. It presents a kind of clean slate (literally) to see how plants recolonize. For existing forests, entangling the effects and even pinpointing the collapse of a species may not be as simple.</p><p>By studying how plant communities recovered after each eruption, the researchers realized that large-seeded species were not fully recovering because the fauna around them had changed since the previous eruption. "We analyzed 151 vegetation surveys on lava flows dated between 1401 AD and 1956 AD," the authors write in the paper. Tracking the changing vegetation over five centuries "has helped to pinpoint the important role that these lost animals played for these forests." The scientists say this is because when the animals that were best suited to disperse their seeds disappeared, the trees also started to fade away from the landscape.</p><p>"It was nice that the findings of this study mirrored some of those we have seen in our research on <u><a href="https://doi.org/10.1073/pnas.1709584114" target="_blank">Guam</a></u> without frugivores, some tree species simply aren't colonizing newly disturbed locations," Wandrag said. "In this case, the much longer history of defaunation, long-term chronosequence of plant communities, and botanical records allowed the authors to link that pattern to the resulting adult tree community."</p>

Mass Extinction Event 2 Billion Years Ago Killed 99% of Life on Earth, Study Finds
04 September 2019

Some two billion years ago, a significant decline of once-abundant oxygen killed as much as 99 percent of all life on Earth in a mass extinction event larger than the one responsible for the dinosaur die-off.
<p>Publishing their work in <a href="https://www.pnas.org/content/116/35/17207" target="_blank">Proceedings of the National Academy of Sciences</a>, a team of researchers describe the catalyst of the Great Oxidation Event (<a href="https://www.sciencedaily.com/releases/2013/01/130117084856.htm" target="_blank">GOE</a>) that occurred between 2.05 and 2.4 billion years ago. In the years leading up to the GOE, oxygen levels in the Earth's atmosphere had increased significantly, resulting in the multiplication of ancient minuscule microorganisms. Suddenly, oxygen levels plummeted in what soon became one of the "most transformative events in all of Earth's history," shifting from "feast" to "famine" conditions that followed in the next 1 billion years, paving the way for complex life as we know it today.</p><p>"We were very surprised," co-author Peter Crockford, a postdoctoral researcher at the Weizmann Institute of Science and Princeton University told <a href="https://www.newsweek.com/earth-massive-die-off-dinosaur-extinction-1457228" target="_blank">Newsweek</a>. "We didn't expect to see such a large signal, nor did we expect to find it in this specific type of sample.</p><p>"Over the 100 to 200 million years before this die-off event there was a large amount of life on the planet, but after this event a huge portion died off," said Crockford. "However, instead of recovering like more recent mass extinctions, the amount of life on the planet or size of the biosphere stayed small for the following billion years of Earth's history—about two billion to one billion years ago."</p><p>But how or why that shift occurred has long been contested — until now. </p>

Barite crystals in the Costello Formation in Canada. Malcolm Hodgskiss
<p>Scientists turned to <a href="https://geology.com/minerals/barite.shtml" target="_blank">barite</a>, a sulfate mineral found in the Belcher Islands in Canada's Hudson Bay that shows the geological record of oxygen in the atmosphere. An analysis of isotope geochemistry found negative values that occurred shortly after the GEO, implying a collapse in primary productivity that triggered a shift in the availability of nutrients like phosphorus. Altogether, this caused an enormous drop in life perhaps due to a decrease in oxygen levels.</p><p>"The fact that this geochemical signature was preserved was very surprising," <a href="https://earth.stanford.edu/news/ancient-die-greater-dinosaur-extinction#gs.0rfimc" target="_blank">said</a> study co-author Malcolm Hodgskiss. "What was especially unusual about these barites is that they clearly had a complex history."</p><p>The increase of life in correlation with atmospheric oxygen confirms a theory known as "oxygen overshoot" whereby photosynthesis from ancient microorganisms and the natural weathering processes of rocks resulted in an increase of oxygen in the atmosphere. Oxygen-emitting organisms eventually exhausted their nutrient supply in the ocean, resulting in declining populations in a world much different than how we know it today, where a stable atmosphere balances oxygen production with consumption. </p><p>The findings shed light into ancient processes that eventually resulted in Earth as we know it today. By further studying how Earth behaves throughout time, scientists say they can better understand how atmospheres operate on planets outside of our solar system, specifically the interlink between the biosphere (where organisms live) and how that relates to levels of oxygen and carbon dioxide in the atmosphere. </p><p>"Some of these oxygen estimates likely require too many microorganisms living in the ocean in Earth's past," said Crockford. "So, we can now start to narrow in on what the composition of the atmosphere could have been through this biological angle."</p>From Your Site Articles
