Story for ProPublica on the mass extinction event that is currently taking place, with animals species going extinct anywhere from 100 to 1,000 times the rates that would be expected under natural conditions. According to Elizabeth Kolbert's The Sixth Extinction and other recent studies, the increase results from a variety of human–caused effects including climate change, habitat destruction, and species displacement. Today's extinction rates rival those during the mass extinction event that wiped out the dinosaurs 65 million years ago.
