Gaia hypothesis

Mother Earth May Have Good Reason to Slaughter Us

Decades ago James Lovelock constructed a principle called the Gaia hypothesis, contending that a biosphere teeming with life works together with inorganic matter to self-regulate conditions for maintaining a livable planet.
The oxygen levels in our air are maintained, and the salinity of the seas – everything that’s needed to keep conditions within the zones which nurture life on the planet.  This is a theory embraced by many deep environmentalists because it offers hope for the future of life forms on the planet.
