Deforestation
1. Deforestation is the removal of a forest or stand of trees where the land is thereafter converted to a nonforest use. The term deforestation is often misused to describe any activity where all trees in an area are removed. However in temperate climates, the removal of all trees in an area – in conformance with sustainable forestry practices – is correctly described as regeneration harvest. In temperate climates, natural regeneration of forest stands often will not occur in the absence of disturbance, whether natural or anthropogenic.
2. Deforestation occurs for many reasons: trees or derived charcoal are used as, or sold, for fuel or as lumber while cleared land is used as pasture for livestock, plantations of commodities and settlements.
3. The removal of trees without sufficient reforestation has resulted in damage to habitat, biodiversity loss and aridity. It has adverse impacts on biosequestration of atmospheric carbon dioxide. Deforested regions typically incur significant adverse soil erosion and frequently degrade into wasteland. Deforestation also causes extinction, changes to climatic conditions, desertification, and displacement of populations as observed by current conditions and in the past through the fossil record.
