_Nature avenges its exploitation_ Vegetative cover slows the speed of falling rain and prevents soil erosion and gully formation — the precursors to landslides and floods. Dense vegetation, by evapo transpiration, also stops nearly 30-40 per cent of rainwater from falling to the ground, thereby significantly reducing run-off. Besides holding the soil together, forests and soil soak water from the rain, release it slowly and prevent water flowing as run-off. So, deforestation brings about slope destabilization, landslides and floods. Given that the Himalayan range is geologically young and still rising, it makes the area vulnerable to erosion and instability. Therefore, it is all the more necessary to take land use change more seriously. thehindu/opinion/op-ed/nature-avenges-its-exploitation/article4834480.ece
