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."

It is pretty amazing that in this moment when the COVID-19 outbreak has much of the country holed up in their homes binging Netflix, the most watched show in America over the last few weeks has been focused on wildlife trade — which scientists believe is the source of the COVID-19 pandemic. Make no mistake: Tiger King: Murder, Mayhem and Madness is about wildlife trade and other aspects of wildlife exploitation, just as surely as the appearance of Ebola, SARS, MERS, avian flu and probably COVID-19 in humans is a result of wildlife exploitation. As a conservationist, this is one of the things I've been thinking about while watching Tiger King. Here are five more:

With the coronavirus pandemic quickly spreading, U.S. health officials have changed their advice on face masks and now recommend people wear cloth masks in public areas where social distancing can be difficult, such as grocery stores.
But can these masks be effective?

Bayer AG is reneging on negotiated settlements with several U.S. law firms representing thousands of plaintiffs who claim exposure to Monsanto's Roundup herbicides caused them to develop non-Hodgkin lymphoma, sources involved in the litigation said on Friday.
With many schools now closed due to the current COVID-19 outbreak, you may be looking for activities to keep your children active, engaged, and entertained.
Although numerous activities can keep kids busy, cooking is one of the best choices, as it's both fun and educational.
Germany's target for renewable energy sources to deliver 65% of its consumed electricity by 2030 seemed on track Wednesday, with 52% of electricity coming from renewables in 2020's first quarter. Renewable energy advocates, however, warned the trend is imperiled by slowdowns in building new wind and solar plants.
