What is erosion in the body?

Erosion is characterized by the partial loss of the epithelium, with the basement membrane left intact. Erosions can be subtle, shallow lesions with loss of only the upper layers of cells and may be difficult to identify.

Why is erosion so bad?

Soil erosion removes valuable top soil which is the most productive part of the soil profile for agricultural purposes. The loss of this top soil results in lower yields and higher production costs. When top soil is gone, erosion can cause rills and gullies that make the cultivation of paddocks impossible.

How do humans slow down erosion?

Baffles or barriers are devices that can help to slow down the flow of water or diver the water from directly flowing downhill creating the erosion.

What good is erosion?

Benefits. Natural soil erosion can play a beneficial role in the environment too. The erosion also helped cleanse the soil of any useless materials, such as rotting tree matter or nutrient-less dirt from the area. The replaced soil can often become nutrient-rich and help plant life thrive.
