Explanation:
Detailed explanation-1: -Harvesting activities reduce surface cover, and compact the soil, leading to increased runoff and erosion. Erosion generally decreases productivity of forests by decreasing the available soil water for forest growth and through loss of nutrients in eroded sediment.
Detailed explanation-2: -Trees in the forests hold the topmost layer firmly by their roots. This does not allow natural forces like wind and water to carry away the top most fertile layer of the soil easily. Hence, forests prevent soil erosion.
