The sixth extinction wave

It's widely agreed that the earth is on the verge of its sixth mass extinction in history. There is an accepted "background" rate of extinctions, but there have been five periods in geological history where it's thought that extinction rates have far exceeded this. With this in mind, we are undeniably in the sixth of these periods right now. Current extinction rates are about 1000 times more than the background rate. There is just one difference - this mass extinction of species is the only one which has been solely brought about by one of the Earth's species: Homo sapiens.

Borneo and Sumatra are both in a recently published list of the 20 areas in the world where extictions are most likey to arise in the near future. For the full article look here:
