Answer: There are various means by which the environment can be affected. These can be human activities or natural calamities.
Landslide is one of the major disaster which can be intensified by human activities.
Mining, deforestation, construction are some of the activities that can loosen the soil which aids to intensify the landslide.
Once the landslide is occurring the loosen soil intensifies the landslide. So, the activities that loosens the soil must be avoided to prevent landslide frequently.
The human activities directly or indirectly affect the nature. The deforestation and the removal of the vegetation for the purpose of development or timber, the land is exposed to the dangers of the landslide. The tress, plants and other vegetation keeps the soil in place with the help of their roots. The soil erosion is prevented by the trees, but the cutting down of them by the humans increases erosion and hence, the risk of landslide.
