     • Forests prevent soil erosion by binding the soil with the network of roots of the different plants and reduce the velocity of wind and rain — which are the chief agents causing erosion.
     • forests reduce pollu­tion and purify the environment.
     • Transpiration of plants increases the atmospheric humidity which affects rainfall and cools the atmosphere.
     • In the forests, the thick layer of humus acts like a big sponge and soaks rain water preventing run-off, thereby preventing flash-floods
