The Gaia Hypothesis

The Gaia Hypothesis proposes that life as a whole on Earth fosters and maintains environmental conditions that will ensure its continuity.

Gaia comes to us from Greek mythology (mother earth) and was known in Roman mythology as Terra.

Organisms must maintain internal conditions within tolerable bounds. Many biological, ecological and even social systems engage in homeostasis, opposing change to maintain internal equilibrium. If the system does not succeed in maintaining or re-establishing its balance, the system will stop functioning.
