Contrary to the common belief that the Earth is simply a dense planet whose only function is a resource for its inhabitants, our planet is in fact a breathing, living organism. When we think of the Earth holistically, as one living entity of its own, instead of the sum of its parts, it takes on a new meaning. Our planet functions as a single organism that maintains conditions necessary for its survival.
James Lovelock published in a book in 1979 providing many useful lessons about the interaction of physical, chemical, geological, and biological processes on Earth.
Throughout history, the concept of Mother Earth has been a part of human culture in one form or another. Everybody has heard of Mother Earth, but have you ever stopped to think who (or what) Mother Earth is?
“the annual pulse of vegetation and land ice.”
WHAT IS GAIA?
Lovelock defined Gaia as “…a complex entity involving the Earth’s biosphere, atmosphere, oceans, and soil; the totality constituting a feedback or cybernetic system which seeks an optimal physical and chemical environment for life on this planet.” ……
HOW DOES GAIA WORK?
The homeostasis regulated by the Earth is much like the internal maintenance of our own bodies; processes within our body insure a constant temperature, blood pH, electrochemical balance, etc. The inner workings of Gaia, therefore, can be viewed as a study of the physiology of the Earth, where the oceans and rivers are the Earth’s blood, the atmosphere is the Earth’s lungs, the land is the Earth’s bones, and the living organisms are the Earth’s senses. Lovelock calls this the science of geophysiology – the physiology of the Earth (or any other planet).
