Modern Gaia can refer to a hypothesis developed by James Lovelock and Lynn Margulis in 1970s that suggests that organisms interact with the inorganic Earth and the Earth with the organisms to create a self-regulating system that maintains conditions for life on Earth. This system involves the biosphere, atmosphere, hydrosphere, and pedosphere.[1]
