cattle also yields negative consequences: additional food‚ water‚ and space -- all provided by the common pasture -- are required to support the extra animals. Should these resources become strained‚ overgrazing will occur. However‚ the individual herdsman himself does not pay the costs of overgrazing. Instead‚ such costs affect all herdsmen as well as the community at large. For example‚ if all of a pastures grass gets eaten‚ then no food remains for the cattle and they will die‚ creating a famine

the air‚ land and water‚ this harms the nature. Bulldozing wetlands and cutting down forest also destroys the nature. These are only few of the activities that contribute to the devastation of nature. Overgrazing and groundwater pumping are some of the activities that damage the land. Overgrazing is one cause of soil erosion‚ in which it turns grassland into desert where soil is eroded and becomes harder for plants and trees to grow in that area which will affect the lives living there.

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.

explained through an example of herdsmen being able to own as much cattle as possible‚ which results in herdsman wanting to maximize their gain even when there are effects of overgrazing. When each herdsman keeps adding another after another there is a tragedy because as each herdsman become ignorant of the impact of overgrazing and the land that is use to other herdsman declines. Another example is overfishing in the oceans. Fishermen catch fish highly for their own gain each day unaware that they
