The idea that iving things and the Atmosphere Oceans And Soils Comprise An Interactive oceans and soils comprise an interactive regulating system the Gaia concept was first proposed nearly thirty years ago Since then researchers have been seeking new connections between ife and the global environment David Schwartzman contributes to that search by examining how the Earth's biosphere regulates itself over geologic time Emphasizing ong term geologic trends not the short term perturbations that
