Scientists on Gaia

The Gaia hypothesis suggests that life is an active participant in shaping the physical and chemical environment on which it depends. Scientists on Gaia is a multidisciplinary exploration of this controversial hypothesis, which was introduced by James Lovelock and Lynn Margulis in the early 1970s. Forty-four contributions detail the philosophical, empirical, and theoretical foundations of Gaia, mechanisms through which planet-wide homeostasis could occur, applicability of the hypothesis to planets other than Earth, possible destabilization by outside forces, and public policy implications.
