James E. Lovelock says the Earth (Gaia) is a superorganism, made up of all living things, interacting with the air, the oceans, and the surface rocks of the planet. He suggests Gaia takes an active role in keeping the planet safe for life, with automatic feedback mechanisms making adjustments as needed. Lovelock describes feedback mechanisms that are widely accepted. It is the implication that Gaia is somehow self-aware that is controversial.

He backs up this idea through his concept of "capabilities."
