30 Million Years to Recover From Extinction?

Scientists have been saying for a while that by the end of this century, half of all species could be extinct. And a new study says that it could take an awfully long time for Earth to recover—30 million years, to be specific.

Back in the Permian era, Earth lost more than 90 percent of all life. Scientists once thought that species rebounded quickly from the hit, but it turns out they were sort of missing the fine print, according to researchers at Bristol University:

Sahney and Benton looked at the recovery of tetrapods – animals with a backbone and four legs, such as amphibians and reptiles – and found that although globally tetrapods appeared to recover quickly, the dramatic restructuring that occurred at the community level was not permanent and communities did not recover numerically or ecologically until about 30 million years later.

And when the species were struggling to rebound back then, they didn’t even have to deal with us.

DEMOCRACY DOES NOT EXIST...

without free and fair elections, a vigorous free press, and engaged citizens to reclaim power from those who abuse it.

In this election year unlike any other—against a backdrop of a pandemic, an economic crisis, racial reckoning, and so much daily crazy—Mother Jones' journalism is driven by one simple question: Will America will move closer to, or further from, justice and equity in the years to come?
