Gaia hypothesis

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.

Her strong influence has been critical for development in three major arenas: the prevalence of symbiosis as a driving force in evolution of eukaryotes, the central role of the microbial world in the dynamics of the past and present biosphere, and the recognition that the earth is a self-regulating system, that is, the Gaia hypothesis.
According to the Gaia hypothesis of James Lovelock and Lynn Margulis (yes, the same one who understood mitochondria ), the planetary system and its innumerable intertwined subsystems has not only been evolving, but also more or less successfully regulating itself to the continued advantage of life.

SANYO drew on the "Gaia hypothesis," a controversial but increasingly well-regarded scientific theory about the biosphere's environmental systems articulated in the early 1970s by the atmospheric scientist James Lovelock.2 Lovelock contended that the biosphere should be understood as a self-regulating organism that maintains the conditions necessary for the planet's diverse species.
