The Gaia Hypothesis regards the Earth as a living planet, an evolving organism in itself. This system as a whole is called Gaia, in homage of the mythical Gaia (γαῖα), the primal Greek goddess personifying the Earth, the Greek version of “Mother Nature”.
This hypothesis, formulated by the scientist James Lovelock and co-developed by the microbiologist Lynn Margulis in the 1970s, postulates what the indigenous peoples have known for centuries, that our planet is a self-regulating intelligence – a fully conscious, living being.
The Gaia Hypothesis describes Earth as a system capable of self-regulation and of mantaining, through interactions between all of its physical, chemical and biological components, the characteristics (composition, temperature, pH, etc.) adequate for the presence of life. It asserts that living organisms and their inorganic surroundings have evolved together, through a cybernetic feedback system operated unconsciously by the biota, as a single living system.
In this respect, the living system of Earth can be thought of analogous to the workings of any individual organism that regulates body temperature, blood salinity, etc. As above, so below. The macrocosmos reflected in the microcosmos, all manifestations of the One.
