Soil is a very important natural resource. So, we should prevent soil erosion. Prevention of soil erosion is called conservation of soil. This is done by:

1. Afforestation : Growing trees on a large scale is called afforestation. As the trees have to be cut down from the forests for various needs, new trees should replace them. In this way, deforestation can be prevented.

2. Growing Plants: When the land is not being used for farming, it is good to grow grass or some other plants to bind the soil particles together. This helps to stop soil erosion.
