'Mass Extinction' Theory: Life On Earth Threatened

"We are at the precipice of the end of the world!" says Chera Van Burg of Species Alliance.
CBS5.com of San Francisco has a detailed article and video report on the current theory that a new mass extinction is beginning. The report uses the Baiji Dolphin as a prime example. It also says that the Congo gorilla population has declined 90 percent since 2002, because of land clearance for Coltan mining, a mineral used in the manufacture of cell-phones.
There is widespread belief among scientists that current species of life are becoming extinct at a rate more than 1,000 times higher than normal.

"According to a consensus of the world's biologists, a mass extinction is unfolding or about to unfold on planet Earth," said David Ulansey of Massextinction.net.
[...]
Biologists believe the six major causes of the present mass extinction are habitat destruction, invasive species, pollution, human overpopulation, human overconsumption, and climate change.
