Explanation:
Deforestation is the reduction of forest area in a given territory, both because of nature or man-made causes.  It results in the loss of habitats for many animal and plant species, the destruction of natural peoples' habitats and livelihoods, and increases soil erosion and large floods in valleys. Often, a previously forested area becomes waste land.
