Question

How can soil erosion harm us?

Answer 1

Hint: Soil erosion is considered the displacement of the upper layer of soil. Soil erosion is a type of deterioration of the land. The complex behavior of soil erosive agents are water, ice, snow, air, plants, animals, and humans, which triggers the natural phenomenon.

Complete answer:
Erosion is often divided into water erosion, glacial erosion, snow erosion, wind erosion, zoogenic erosion and anthropogenic erosion in conjunction with the agents. The removal of soil by erosion decreases the available environment for food or other plant growth. Also where the soil may be unsuitable for agriculture, plants anchoring the soil control the flow of rain and river water. Not only soil erosion deplete the cover of vegetation, but it seems to be more harmful flows of water during rain or snow melt. For more ecosystems, including human ones, flooding is devastating. It has contributed to increased stream and river contamination and sedimentation, clogging these rivers and causing declines in fish and other species. And degraded land is also less capable of holding onto water, which can make flooding worse. Soil is a finite resource, meaning that during a human lifetime, its depletion and decay are not recoverable. Soils influence the food we consume, the water we drink, the air we breathe, the health of all life on the earth, and our health.

Therefore, soil erosion causes a major effect for human survival.

Note:
Human activities have risen globally by 10-50 times the rate at which erosion occurs. Both 'on-site' and 'off-site' issues are caused by severe erosion. The on-site effects include declines in agricultural production and the off-site effects include waterway sedimentation and water body eutrophication.
