The two main causes of desertification are loss of vegetation from arid or semi-arid areas and overcultivation of average land. In the first case, native vegetation is removed, either by grazing animals or by the deforestation, leaving the soil exposed to the sun and wind, which dry it up and blow it away, leaving only dry barren ground where nothing grows. In the second case, farmers introduce too muc vegetation into the soil, and through improper management, deplete the soil of nutrients to such an extent that it can no longer support life. Natural events, such as drought and climate change, can also cause desertification in marginal areas.
