Some of these are human causes and some are physical causes. Overgrazing‚ deforestation‚ overpopulation‚ fertilizer and pesticide use and conflict are some examples of human causes. Some physical causes are rising temperatures‚ falling rainfall‚ wind‚ flash floods and topography. Soil degradation has many consequences

The effect‚ of overgrazing by one additional animal appears minimal so the other rational herdsmen conclude to add an additional animal to their own herd. Since all the herdsmen are thought to be rational this conclusion is reached by each of them. The effect of‚ overgrazing will become detrimental to the pasture and all the animals will die.

Cattle production‚ for example‚ is a major cause of soil erosion due to overgrazing of land‚ which creates deserts out of grasslands. Cattle production also creates water pollutions through organic waste and the use of chemicals in animal feed. In addition‚ cattle production pollutes the air. Grain-fed cattle contribute significantly
