Satisfy measure of afforestation and deforestation
Answers
Answer:
Differences between deforestation and afforestation are elucidated. Afforestation is planting of trees in barren lands to increase the area under forests. Deforestation has many ill-effects on the environment. Afforestation influences the climate of a particular area and shows positive effect on the environment.
Deforestation, clearance, clearcutting or clearing is the removal of a forest or stand of trees from land which is then converted to a non-forest use.[2] Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests.[3] About 31% of Earth's land surface is covered by forests.[4]
Deforestation can occur for several reasons: trees can be cut down to be used for building or sold as fuel (sometimes in the form of charcoal or timber), while cleared land can be used as pasture for livestock and plantation. The removal of trees without sufficient reforestation has resulted in habitat damage, biodiversity loss, and aridity. It has adverse impacts on biosequestration of atmospheric carbon dioxide. Deforestation has also been used in war to deprive the enemy of vital resources and cover for its forces. Modern examples of this were the use of Agent Orange by the British military in Malaya during the Malayan Emergency and by the United States military in Vietnam during the Vietnam War. As of 2005, net deforestation rates had ceased to increase in countries with a per capita GDP of at least US$4,600.[5][6] Deforested regions typically incur significant adverse soil erosion and frequently degrade into wasteland.
