Which one of the following is the indirect use of forests ?

Some of the indirect uses of forests include:

prevention and control of soil erosion, flood

control, checks on spread of deserts, increase

of soil fertility, and effect on climate. Forests

play a significant role in the prevention and

control of soil erosion by water and wind. The

destruction of forest cover leads to increased

runoff of rain water and its diminished seepage in soil.
