Write a proposal for three things that could be done to prevent erosion, and explain why they would work.

There are different ways to prevent erosion of soil. They are as follows.

Erosion is a natural phenomenon which is caused by friction of soil particles with air, or solution forming with water. This erosion can lead to massive land slides and severe loss of lives with different other loses. So to prevent soil erosion,

Firstly, plants must be planted wherever we get free space. Spaces for plants must be done. The roots of plants anchor the soil particles and resists the action of flowing water and blowing air on soil to wash them away.

Planting grasses on the empty soil is a very good way. The grasses form a mat like structure with their network over the top soil. This prevents washing of soil in case of heavy rain and also prevents degradation of soil quality.

The embankment of ponds or rivers should also be done to prevent landslides into the water bodies.
