How does over gra
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals.
Many lands that were once covered in vegetation are now barren and dry deserts. This overall change is known as desertification, which is the conversion of habitable and fertile land to uninhabitable desert.
Overgrazing occurs when farmers allow livestock to graze to the point where they damage the vegetation. This can happen when farmers have too many livestock in a small area or when they keep livestock in an area for a long period of time.
Deforestation is the process of removing trees and transforming a forest into cleared land. This is often done to make room for farming or housing for the growing human population. Both overgrazing and deforestation can lead to desertification because they remove or damage the vegetation that is protecting the land and keeping it moist and fertile.
If plants are removed, the soil will have nothing protecting it, and it will be more susceptible to erosion by wind. This will reduce fertility of the land because the top layer of soil that will be blown away by wind is often the richest in nutrients. Once this top layer of soil is removed, the land will no longer be fertile and will be unable to support the growth of vegetation. Eventually, the land will become so dry and devoid of vegetation that it will be classified as a desert.
