Deforestation is the process of cutting down trees by man, which eventually lead to the the sparseness of trees in otherwise forested areas. The reasons for cutting trees by man may include: habitation by man, clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing as well as mining of minerals.
Deforestation leads to many adverse effects on both man and his environment. These adverse effects include:
Loss of biodiversity in the forests which may lead to extinction of species.; when forest areas are cleared, plants and animals who live in these forests lose their homes and some may eventually die off due to inability to survive in other habitats
Increase in temperature of the earth: Trees serves to cool the earth by removing some gases which cause heating of the earth from the earth. Such gases include carbon dioxide. When these tree are removed, these gases accumulate in the atmosphere leading to increase in earth's temperature.
Also, since tree absorb some gases while releasing others into the atmosphere, when these trees are cut, there would be an imbalance of these atmospheric gases.
