Is a sixth mass extinction already happening?

The goats devastated the island’s vegetation, wiping out the Pinta tortoises’ habitat.   You may not have heard of Lonesome George. But his death was a sign of our times.   Two vertebrate species go extinct every year amid a man-made mass extinction unrivaled since the dinosaurs died out 66 million years ago. Today, the phenomenon is known as the Sixth Extinction. Some 200 species have disappeared over the past century — a pace approximately 100 times faster than the “normal” rate.   At the turn of the millennium, Nobel prize winning atmospheric chemist Paul Crutzen and his colleague Eugene Stoermer published an article suggesting th
