The world is embarking on its sixth mass extinction with animals disappearing about 100 times faster than they used to, scientists warn, and humans could be among the first victims of the next extinction event.
Not since the age of the dinosaurs ended 66 million years ago has the planet been losing species at this rapid a rate, a study led by experts at Stanford University, Princeton University and the University of California, Berkeley said.
The study "shows without any significant doubt that we are now entering the sixth great mass extinction event," co-author and Stanford University professor of biology Paul Ehrlich said.
