Today the destruction of forests has increased along with population growth. People do not know that the trees are our life-givers. From trees, we get the life-giving air (oxygen). With trees and forests, we meet many of our needs. At the same time, forests cause rains. But due to population explosion, humans are indiscriminately harvesting forests for their needs. That is why the existence of forests today is in danger. Consequently, human life is also in danger.
According to an estimate, 11 million hectares of forest are harvested in the world per year. In India alone, one million hectare of forest is being cut down. The pressure of urbanization, the growing population and the craving for the rapid development have deprived us of green cover.
Trees are cut illegally in forests. On one hand, the government is spending crores of rupees for environmental protection, on the other; the wood mafia has no qualms in denuding the forest of tree cover. The mafia has been cutting the trees and transporting the wood with a vengeance.
Deforestation results in soil, water and air erosion, which result in the loss of an estimated amount of more than 16,400 crore trees each year. Deforestation adversely affects the productivity of the land. It causes several ill-effects:
Various Effects of Deforestation/Cutting of Trees
Floods and Droughts: Soil erosion increases the soil flows, due to which the specific cycle of flood and drought is started.
Cutting forests on mountain slopes obstructs the flow of rivers towards the plains, which have an impact on their water efficiency, so that the water rapidly comes downwards.
Deforestation leads to land erosion arises because the trees play an important role in maintaining the surface of the mountains and cause natural barriers to the rapidly rising rain water. Consequently the water level of the rivers increases suddenly, causing floods.
Loss of Soil Fertility: When the fuel becomes inadequate, the cow dung and the vegetable residue are used like fuels to make food. Because of this, every part of the plant is gradually used and nothing goes back in the soil. After some time the drift of this nutrition influences the productivity of the soil, it causes degradation of soil-fertility.
