    The top layer of soil is exposed: If the top layer of soil is exposed it will wash away with water. The removal of top layer will gradually convert the fertile land into deserts. Moreover the soil washed away with water will be deposited in the river bed resulting in decreasing the depth of rivers. The chances of floods will increase many folds.

    (a) Wild animals: The natural habitat of the animals is destroyed by deforestation. Without the natural habitat the animals are left with no place to live and breed. As a result of this many animals are at the verge of extinction.
    (b) Environment: Deforestation has resulted in Global warming. Carbon dioxide is not absorbed by plants and it gets accumulated in the atmosphere. It has an adverse effect on our ecosystem.
    (c) Villages (Rural areas): The rural areas largely depend on forests for fuel, fruits, wood etc. Deforestation has reduced their resources and the uninhabited animals are also a danger for the villagers
    (d) Cities (Urban areas): Cities are not directly affected by deforestation. But the changes in the climate results in calamities like flood and droughts which affect the cities also. It also leads to global warming.
    (e) Earth: Deforestation has converted the fertile lands into deserts. The natural calamities like floods and droughts are also the result of deforestation. The climate of earth has been changed due to deforestation.
    (f) The next generation: Deforestation has affected our climate very much. Many species are at the verge of extinction because of deforestation and some species are already extinct. The next generation may not be able to see many beautiful and attractive fauna and flora. It may have to suffer from the effects of global warming, no fuel and no paper etc.
