Question

What are the effects of deforestation?

• A. Increase in the level of CO${}_2$ in the atmosphere
• B. Barren land
• C. Both A and B
• D. Fertile land

Answer 1

Answer: (C)

Both A and B

Deforestation is the cutting down of trees of the forest. Due to this, there is a decrease in the number of trees that can consume CO${}_2$2 and give out oxygen through photosynthesis. Thus, there is an increase in atmospheric CO${}_2$2 levels.

The roots of the trees hold soil particles together. Without the trees, the fertile topsoil can be washed by water and wind, leaving the infertile/barren land behind. Vegetation is not possible on barren land.

So, the correct answer is option C.
