उत्तर
Soil conservation refers to the methods of protecting the soil from erosion. Roots of the trees protect the soil by holding it in place against wind and water erosion. Re-afforestation means replanting trees which have been cut down. For every tree that is cut, two trees are grown. In this way forest cover is increased.
