mass extinction is


Humans are currently causing the largest mass extinction of species since the extinction of the dinosaurs 65 million years ago. If this trend continues unchecked, 20 percent of all species will be extinct in the next 30 years and half of all species will be extinct in the next 100 years.

Current species extinction rates are about 1000 times higher they were before the industrial revolution making this the fastest extinction event that has ever happened on earth. In contrast, the last major extinction, 65 million years ago, took a few hundred thousand years to kill the dinosaurs . The current mass extinction has been well-documented by scientists around the world but is under-reported by the media. Because these facts are not widely known, the most effective thing you can do is inform yourself and let others know what is happening.
