Gaia hypothesis

an hypothesis developed by the British scientist, James Lovelock, to suggest that the earth is one living system, such that the distinction between organic and inorganic matter is false. Gaia was an ancient Greek goddess of the earth and fertility Contrary to established scientific notions, Lovelock argues that a conducive physical environment did not first exist within which living organisms could develop, but rather the living organisms create the necessary physical environment for their survival. This leads to the concept of the planet earth as a CYBERNETIC system. In the late 1980s, the Gaia movement emerged as one of the environmental groups increasingly influential in national and international politics.
