Answers
Answer:
1. The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people
2.Forests are rich in vegetation. Herbs, shrubs and trees in the forests hold the top most layer firmly by their roots. This does not allow natural forces like wind and water to carry away the top most fertile layer of the soil easily. Hence, forests prevent soil erosion.
3 We depend on forests for our survival, from the air we breathe to the wood we use. Besides providing habitats for animals and livelihoods for humans, forests also offer watershed protection, prevent soil erosion and mitigate climate change.
