(By some accounts, the now-denuded Zagros Mountains in western Iran hosted this revolution."Zagros" is thought to derive from Zagreus, the Greek son of Zeus who was dismembered and eaten and later merged with Dionysus.) Modern agriculture largely relies on keeping ecosystems in perpetually immature states of succession in which chemically stimulated productivity remains high until the soils are too depleted to grow anything.

Animism: a derogatory anthropological term for what most human cultures have believed throughout prehistory: that the Earth is alive and reactive, as are its many places.Agricultural Pollution: pesticides, fertilizers, wastes, erosion dust, runoff from fields, and animal infections are a few of the varieties. (Most of the other half is industrial.)Air Pollution: sulfur oxides and particulates from industrial plants burning fossil fuels are the current worst forms of air pollution. Most air pollution derives in one form or another from the use of petroleum products, oil in particular. Albedo: the luminosity shining from a reflective surface. About 1/3 of the sun’s radiation is reflected back into space, with the remaining 42% warming the land and air and 23% moving water through the hydrologic cycle. Allopatric: separated, apart, as with a group of organisms living away from the original group.According to the Environmental Protection Agency, half the water pollution in the U. (There seems to be quite a bit of research done on organisms separated from their original group.Agriculture: large-scale cultivation of the land, with resulting specialization of labor, domestication of plants and animals, identification with one’s sedentery social group, and a radical separation from the natural world.The Agricultural (Neolithic) Revolution began ten thousand years ago in the Fertile Crescent, where extensive irrigation turned once-fertile croplands into barren salt pans.Synthetic ammonia is a key component of artificial fertilizers.

Analogue Forestry: a method for restoring ecosystems, developed from local Sri Lankan home gardens by the Neo-Synthesis Research Centre (NSRC), that seeks to bring back what grew there originally.

Often has the effect of making the bed of a stream or flood plain rise.

Also, a phase of forest biomass accumulation in the years that follow a harvest.

Angle of Repose: the steepest angle that slope, rock, or detritus material settles into without toppling.

Builders of flood-prone roads and sliding hillside homes in California ignore the angle of repose so often that it could be renamed the angle of depose.

Animals: the animal kingdom branches into the deuterostomes (mouth and anus develop separately) and the protostomes.
