D
Creation of Shelter belts
Solution:
Creation of Shelter belts is not a reason for the depletion of forests. Forest covers in the world are fast depleting owing to multiple reasons. It includes clearing forests for mining, quarrying, and related activities. Overgrazing leads to a decrease in forest cover. The development of river valley projects for electricity generation and water supply requires large areas of forest to be cleared. The increasing population density demands more space for living. The forest lands are getting converted to agricultural lands or for infrastructure development.
