Question

Which of the following is not true about deforestation?

• A. Population explosion is one of the reasons for deforestation.
• B. Cleaning of forest for agriculture causes deforestation.
• C. Deforestation can also occur naturally.
• D. There is no environmental impact due to deforestation.

Answer 1

The correct option is D There is no environmental impact due to deforestation.

The statement 'there is no environmental impact due to deforestation' is completely incorrect as deforestation can cause a lot of harm to the environment. Some of them are:

1) Soil erosion (roots of trees help in holding the soil particles)

2) Climate change (global warming occurs due to the release of carbon dioxide which is absorbed by trees during photosynthesis)

3) Desertification (due to soil erosion, the fertile topsoil washes away exposing the infertile land on which plants do not grow)

4) Flooding (trees help in retaining the water-holding capacity of the soil)

5) Loss of biodiversity (animals dwelling in the forest lose their habitat)
