Q. Write a note on how forests influence the quality of our air, soil and water resources.

Ans. Forests influence the quality of air, soil and water resources in the following ways:

Influence of forests in controlling the quality of air:
1. Forests help in minimising the level of CO₂ in the atmosphere. This prevents greenhouse effect and global warming.
2. Forests reduce environmental temperature which in turn increases the rate of photosynthesis in plants in the surrounding regions.
3. Some of the trees has the ability to absorb harmful gases present in the atmosphere, e.g., Jamun trees can absorb compounds of lead easily.
Influence of forests in controlling the quality of soil:
1. The roots of huge trees spread in a larger area and prevent erosion of topsoil by holding the soil particles tightly.
2. Forests also regulate biogeochemical cycles which are responsible for cycling of nutrients and making them available for the plants in the soil.
3. Many of the decomposing bacteria and nitrogen-fixing bacteria live in close association with the roots of the trees.
Influence of forests in controlling the quality of water :
1. Forests help in returning pure water back to the surface of earth through rains.
2. Forests help in maintaining the water cycle as well as water resources of the earth.
