The Gaia hypothesis, developed by British atmospheric chemist James Lovelock and U.S. biologist Lynn Margulis, proposes that planetary processes are neither simply geological and chemical, nor just geochemical; they are geophysiological. Variables such as the mean global temperature, the gaseous composition of the atmosphere, and the salinity and alkalinity of the oceans are sensitive to biological activity.
