In nature‚ change usually takes a long time to occur. The biome eventually adapts as animals and plants that have characteristics that aren’t suited to the occurring change eventually die out and those more suited to the change‚ remain alive and breed and pass their characteristics along to future generations.

Desertification in Africa Land covers “ 14.9 billion hectares of the earth’s face”. According to the United Nations data‚ “ 6.1 billion hectares are dryland” of which one billion hectares are “ naturally hyper arid desert”(www.eden-foundation.org). The rest has either become desert or is being threatened by desertification. This natural process has caused misery among those most directly caught in its path‚ turning productive land into dryland.

| | What Causes Desertification? -Overgrazing Overgrazing was not as large of a problem long ago because animals would move in response to rainfall. People would move with the animals so it prevented overgrazing in such areas. Now‚ humans have a steady food supply so they do not have to move about. Therefore‚ people use fences to keep their animals in one place which causes overgrazing. (Desertification‚ 2001) -Farming of Average Land Farming of average land is causing desertification worldwide
