on his own in 1972, and then later in 1973 with American microbiologist Lynn Margulis, Lovelock formally proposed the idea of Gaia as a control system. The name for the complex system of climate control has remained "Gaia" since then, and in 1979 his book, Gaia - a new look at life on Earth first presented the Gaia hypothesis to the wider public. Gaia has become a very important in the human.The Gaia hypothesis...suppose(s) that the atmosphere, the oceans, the climate, and the crust of the Earth are regulated at a state comfortable for life because of the behavior of living organisms. Specifically, the Gaia hypothesis said that the temperature, oxidation state, acidity and certain aspects of the rocks and waters are at any time kept constant, and that this homeostasis is maintained by active feedback processes operated automatically and unconsciously the biota. Solar energy sustains comfortable conditions for life. The conditions are only constant in the short term and evolve in synchrony with the changing needs of the biota as it evolves. Life and its environment are so closely coupled that evolution concerns Gala, not the organisms or the environment taken separately."The mutualistic system that James Lovelock has suggested encounters all of life on Earth. Diverse groups of organisms all around the world (plankton in the oceans, trees in the forests, bacteria in swamps etc.) are working together to help stabilize the Earth's environment, and keep the Earth habitable for life itself. For instance, they keep the Earth's temperature fairly constant despite long-term variations in the sun's energy output (preventing the Earth from either freezing or getting too hot for life), and they help to keep the atmosphere filled with oxygen, and prevent the oceans from becoming filled with nasty nitric acid. They help maintain a reasonable amount of rainfall over the Earth's land surface, and transport vital nutrients (such as iodine) needed by...
