Detailed explanation-1: -These negative impacts include: destruction of forest cover, loss of biodiversity, ecological imbalance, soil compaction, soil erosion, flooding, desert encroachment and disruption of hydrological cycle.
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.
