Which one is the consequence of deforestation?
Chances of natural calamities such as droughts, desertification and floods increase.
Forests and trees stabilize the soil, prevent erosion, enhance the land's capacity to store water, and moderate air and soil temperatures. Deforestation leads to lesser number of trees on earth. Plants consume carbon dioxide from atmosphere for photosynthesis. Lesser number would mean less amount of carbon dioxide will be used up resulting in increased amount of carbon dioxide in atmosphere. Carbon dioxide traps the heat rays reflected by earth leading to global warming. As the temperature on the earth increases, it disturbs the water cycle & reduces rainfall. This causes drought.Trees prevent soil erosion. Due to deforestation fewer trees are left which results in soil erosion. Removal of the top layer of the soil exposes the lower, hard and rocky layers. This soil is less fertile which slowly gets converted into deserts. It is called as desertification. Due to deforestation, the water holding capacity of the soil reduces. During heavy rains, the movement of water from the soil surface into the ground is reduced, so most of the water remains on the ground leading to floods.
