उत्तर
raising forests
Explanation:
Soil erosion is the removal and transportation of the top layer of soil from its original position to another place with the help of strong winds and fast running rain water.
Soil erosion can be prevented by raising forests, as the roots of plants have an important role in preventing soil erosion. Roots hold the soil particles and reduce the exposure of soil to air and wind, thereby reducing its displacement.
