An author asserts: We are currently in the midst of what scientists consider the sixth mass extinction in planetary history, with between 150 and 200 species going extinct daily, a pace 1,000 times greater than the “natural” or “background” extinction rate. This event may already be comparable to, or even exceed, both the speed and intensity of the Permian mass extinction. The difference being that ours is human-caused, isn’t going to take 80,000 years, has so far lasted just a few centuries and is now gaining speed in a non-linear fashion.
