Gaia Hypothesis

Definition

The Gaia Hypothesis is a scientific theory proposed by James Lovelock, suggesting that the Earth and its biological systems behave as a single, self-regulating entity. This concept implies that life interacts with the Earth's environment to maintain conditions suitable for life, drawing connections to ancient beliefs about the Earth as a living organism and its reflection in various mythologies and religions.
