Descrição: (Sometimes the jumps between places and eras are quite sudden.) He identifies a common pattern in most of these societies: the development of agriculture in fertile valleys leads to a growing population, the rising food demands of a growing population trigger the forming of marginal land, these sensitive lands soon become eroded, and agricultural yields decrease. Montgomery attributes such land degradation to the use of heavy farm machinery and of agrochemicals-the fundamentals of modern industrial agriculture-pointing out that the discovery and large-scale supply of mineral fertilizers made nutrient provision from soils seem superfluous, which led to neglect of soil fertility, the segregation of crop production from animal husbandry, and the rise of largescale monocultures.
