"James Lovelock's Gaia hypothesis conceives of the planet as an active control system. It posits the existence of feedbacks at the global level which, so far, have served to keep the earth's surface habitable within a tolerable range, despite significant external changes, including changes in the radiation from the sun. However, with severe human-induced activity, that is now beginning to change."
