Geophysiology
Geophysiology (Geo, earth + physiology, the study of living bodies) is the study of interaction among living organisms on the Earth operating under the hypothesis that the earth itself acts a single living organism (Gaia).
The term "geophysiology" was popularized by James Lovelock as part of his writing about the Gaia hypothesis.
It seeks to express the outcome of the Gaia hypothesis in scientific terms.
