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

Explanation

Forests influenee all the three sources like air, water and soil.
(i) Forests maintain the balance between carbon dioxide and oxygen. They need `CO_2` for photosynthesis and release `O_2` in this process. similarly they need `O_ 2` for respiration and release `CO_2` in this process.
(ii) Forests prevent soil erosion. The roots of plants hold soil tightly and prevent them from blown away by wind and water.
(iii) Forests are also essential for recharging the water sources. They play important role in maintaining, water cycle by transpiration. They also help in the cycle of under-ground and surface water.
In this way forests affect the quality of air water and soil.
