Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. [1] Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. [2]
Deforestation is a threat to forests according to foresters. Deforestation is the permanent destruction of forests and woodlands. Deforestation is brought about by commercial logging, conversion of woodlands to agricultural land, and the felling of trees for firewood and building material. [18]
Forest cover in the Eastern United States reached its lowest point in roughly 1872 with about 48 percent compared to the amount of forest cover in 1620. The majority of deforestation took place prior to 1910 with the Forest Service reporting the minimum forestation as 721,000,000 acres (2,920,000 km 2) around 1920. [2]

Biophysical mechanisms by which forests influence climate. Irreversible deforestation would result in a permanent rise in the global surface temperature. [23] Moreover, it suggests that standing tropical forests help cool the average global temperature by more than 1 °C or 1.8 °F.
Deforestation threatens many forest ecosystems. Deforestation occurs when humans remove trees from a forested area by cutting or burning, either to harvest timber or to make way for farming. Most deforestation today occurs in tropical forests.
Demand for forest products, especially wood, resulting from earlier deforestation, also creates market incentives to plant trees and more effectively manage forest resources. [12] Due to forestry intensification, higher forest productivity saves remaining forests from exploitation pressures. [13]
