I don't think anyone is saying Global Warming could kill the planet, but it could cause a runaway greenhouse effect that would make life difficult or impossible.
Why mass extinctions occur is hotly debated. The Permian Extinction (The Great Dying) caused 97% of the species alive at the time to go extinct, and no one really knows why. But there is little doubt that man is causing species to go extinct at an alarming rate, mostly due to loss of habitat (deforestation), over-hunting and overfishing, and pollution. It is estimated that over 1,000 species of plants and animals go extinct every day; most of these are insects but still this is an alarming statistic. It is up to us to preserve and maintain the life on this planet, or we may be next on nature's extinction list.
