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

    Answer:

                      Forests influence the quality of our air, soil and water resources in the following ways: Air: Forests maintain the balance between carbon dioxide and oxygen by taking in carbon dioxide and giving out oxygen through photosynthesis. (ii) Soil: Forests prevent soil erosion. The roots of plants hold the soil tightly and prevent it from being eroded away. Moreover, they also check the speed of wind and help in case of flooding. (iii) Water: Forests are also essential for replenishing the water sources. They play an important role in maintaining water cycle by the process of transpiration.
