Life leaves our planet as we take it over.
Our biosphere, its living constituents, and the workings of human societies have laws of large numbers and bulk averages. This is important, because our crisis planetary ecology is entirely the fault of our exponential growth. Gaia has never before been hit so hard and fast from within. Humanity is fast engineering its massive destructive coup of all life systems. Gaia is our solar energy renewed biosphere, our very thin crust,oceans and atmosphere of life-compatible chemistry and temperatures, that wraps our planetary sphere.
