Question
Explain how, deforestation leads to reduced rainfall.
✓
Answer
Plants need carbon dioxide for the process of photosynthesis. Fewer trees would mean that less carbon dioxide will be used up resulting in its increased amount in the atmosphere and increase in greenhouse effect. The increase in temperature on the earth disturbs the water cycle and may reduce rainfall. When number of trees are reduced then less amount of water is evaporated and hence the reduced evaporation leads to reduced rainfall.
