Because it causes soil loss in some areas

Explanation:

Soil erosion is responsible for soil loss in some areas and soil deposition in other places.

When soil is eroded by wind, ice, gravity or water, soil is lost from where it is formed. This original place of soil is important. Why? Because conditions exist there to form soil. Upper soil layer is fertile. Due to soil erosion, soil (upper soil) is lost. Soil formation is a very slow process.

Soil erosion causes siltation in rivers, dams, etc. In some areas, huge river deltas are formed (such as River Nile delta) because of soil erosion. Such places are good for agriculture but not good for urbanization. However, some people do not care about it, they just want to construct buildings on alluvium type soils. This is a problem since such soils are not as strong as bedrock.

Soil loss due to erosion causes agricultural income loss since agricultural areas that are subject to soil erosion becomes less fertile.
