Gaia philosophy


Gaia philosophy (named after Gaia, Greek goddess of the Earth) is a broadly inclusive term for related concepts that living organisms on a planet will affect the nature of their environment in order to make the environment more suitable for life. This set of theories holds that all organisms on a life-giving planet regulate the biosphere in such a way as to promote its habitability. Gaia concept draws a connection between the survivability of a species (hence its evolutionary course) and its usefulness to the survival of other species.

While there were a number of precursors to Gaia theory, the first scientific form of this idea was proposed as the Gaia hypothesis by James Lovelock, a UK chemist, in 1970. The Gaia hypothesis deals with the concept of Biological homeostasis, and claims the resident life forms of a host planet coupled with their environment have acted and act like a single, self-regulating system. This system includes the near-surface rocks, the soil, and the atmosphere. Today many scientists consider such ideas to be unsupported by, or at odds with, the available evidence (see recent criticism). These theories are however significant in green politics.

There are some mystical, scientific and religious predecessors to the Gaia philosophy, which had a Gaia-like conceptual basis. Many religious mythologies had a view of Earth as being a whole that is greater than the sum of its parts (e.g. some Native American religions and various forms of shamanism).

Lewis Thomas believed that Earth should be viewed as a single cell; he derived this view from Johannes Kepler's view of Earth as a single round organism.

Isaac Newton wrote of the earth, "“Thus this Earth resembles a great animall or rather inanimate vegetable, draws in æthereall breath for its dayly refreshment & vitall ferment & transpires again with gross exhalations, And according to the condition of all other things living ought to have its times of beginning youth old age & perishing.”
