Soil erosion can be prevented by adding a few plants or trees where the soil typically erodes, adding fencing gullies and removing wildlife that will eat the vegetation. The eroding of the soil occurs naturally whenever there is moving water or even exposure to the wind.
When erosion occurs in waterways, it can result in an overflow of silt. Silt can damage plants and animals in streams, lakes and harbors just as easily as pollution can by covering up young plants and killing animals. Soil erosion can often be prevented if individuals and companies are more careful about the way the land is being used.
