I was wondering about the acceptance among people studying or central to biology for the theory of how all the systems on Earth function in accordance with each other; and are self-regulating processes For example; the deposition of limestone encouraging tectonic shift as well as the development of volcanoes can be thought as Earth using a biotic factor to usher along an abiotic process. Gaia theory is very interesting to me; and seems rather convincing; considering that a mathematical model of it (Daisyworld) is so easily presented and understood.
