It Will Take 10 Million Years to Recover From This Man-Made Apocalypse
By Jordan Davidson
The climate crisis has us spiraling towards higher temperatures while also knocking out marine life and insect species at an alarming rate that continues to accelerate. But, just how long will it take Earth to recover? A new study offers a sobering answer: millions of years.
The researchers tried to answer how long it takes biodiversity to recover following a mass extinction. Their paper, published in Nature Ecology and Evolution, looked at the fossil records of plankton which existed for nearly 20-million years near the last mass extinction, which killed off most dinosaurs and 80-percent of Earth's animals, nearly 66 million years ago. Species diversity recovered after 10 million years, Newsweek reported.
"From this study, it's reasonable to infer that it's going to take an extremely long time — millions of years — to recover from the extinction that we're causing through climate change and other methods," said study co-author Dr. Andrew Fraass to Newsweek. "It is an apt warning about the time it takes to recover from massive losses in species."
The findings have striking implications for the long-term health of the planet and the future of humanity as we confront a climate crisis, habitat destruction and invasive species, all of which parallels ancient times, according to a University of Bristol press release.
"This should serve as an important reminder: some ecological niches lost due to anthropogenic climate change will never reappear," the authors wrote in their study. Essentially, the Earth will be drastically different after a mass extinction, according to Forbes.
The study complements other recent studies that have found declining plant and animal populations as a threat to the global food chain. Earlier this year, a separate study published in Biological Conservation found insect populations declining so rapidly that 40 percent of insect species threatened with extinction.
"The repercussions this will have for the planet's ecosystems are catastrophic to say the least, as insects are at the structural and functional base of many of the world's ecosystems since their rise at the end of the Devonian period, almost 400 million years ago," the study authors wrote.
The authors of the insect study chose their words carefully to stress the importance of insects to all life on the planet.
"We only use the word "catastrophic" once, and we use it very carefully," said study co-author Francisco Sanchez-Bayo of the University of Sydney to Civil Eats. "We chose that word deliberately: If 30 percent of insects, the largest group of animals on Earth, are in danger, that is catastrophic. Damage from a tropical cyclone can be characterized as catastrophic, but that is localized. This is global. This is a true catastrophe."

Company Safety Data Sheets on New Chemicals Frequently Lack the Worker Protections EPA Claims They Include
By Richard Denison
Readers of this blog know how concerned EDF is over the Trump EPA's approval of many dozens of new chemicals based on its mere "expectation" that workers across supply chains will always employ personal protective equipment (PPE) just because it is recommended in the manufacturer's non-binding safety data sheet (SDS).

From 2009 to 2012, Gregory Jaczko was chairman of the Nuclear Regulatory Commission, which approves nuclear power plant designs and sets safety standards for plants. But he now says that nuclear power is too dangerous and expensive — and not part of the answer to the climate crisis.

When Greg Wetherbee sat in front of the microscope recently, he was looking for fragments of metals or coal, particles that might indicate the source of airborne nitrogen pollution in Rocky Mountain National Park. What caught his eye, though, were the plastics.
In a big victory for animals, Prada has announced that it's ending its use of fur! It joins Coach, Jean Paul Gaultier, Giorgio Armani, Versace, Ralph Lauren, Vivienne Westwood, Michael Kors, Donna Karan and many others PETA has pushed toward a ban.
This is a victory more than a decade in the making. PETA and our international affiliates have crashed Prada's catwalks with anti-fur signs, held eye-catching demonstrations all around the world, and sent the company loads of information about the fur industry. In 2018, actor and animal rights advocate Pamela Anderson sent a letter on PETA's behalf urging Miuccia Prada to commit to leaving fur out of all future collections, and the iconic designer has finally listened.
If people in three European countries want to fight the climate crisis, they need to chill out more.
"The rapid pace of labour-saving technology brings into focus the possibility of a shorter working week for all, if deployed properly," Autonomy Director Will Stronge said, The Guardian reported. "However, while automation shows that less work is technically possible, the urgent pressures on the environment and on our available carbon budget show that reducing the working week is in fact necessary."
The report found that if the economies of Germany, Sweden and the UK maintain their current levels of carbon intensity and productivity, they would need to switch to a six, 12 and nine hour work week respectively if they wanted keep the rise in global temperatures to the below two degrees Celsius promised by the Paris agreement, The Independent reported.
The study based its conclusions on data from the UN and the OECD (Organisation for Economic Co-operation and Development) on greenhouse gas emissions per industry in all three countries.
The report comes as the group Momentum called on the UK's Labour Party to endorse a four-day work week.
"We welcome this attempt by Autonomy to grapple with the very real changes society will need to make in order to live within the limits of the planet," Emma Williams of the Four Day Week campaign said in a statement reported by The Independent. "In addition to improved well-being, enhanced gender equality and increased productivity, addressing climate change is another compelling reason we should all be working less."
Supporters of the idea linked it to calls in the U.S. and Europe for a Green New Deal that would decarbonize the economy while promoting equality and well-being.
"This new paper from Autonomy is a thought experiment that should give policymakers, activists and campaigners more ballast to make the case that a Green New Deal is absolutely necessary," Common Wealth think tank Director Mat Lawrence told The Independent. "The link between working time and GHG (greenhouse gas) emissions has been proved by a number of studies. Using OECD data and relating it to our carbon budget, Autonomy have taken the step to show what that link means in terms of our working weeks."
Stronge also linked his report to calls for a Green New Deal.
"Becoming a green, sustainable society will require a number of strategies – a shorter working week being just one of them," he said, according to The Guardian. "This paper and the other nascent research in the field should give us plenty of food for thought when we consider how urgent a Green New Deal is and what it should look like."
