Plain how soil erosion and soil …

The removal of fertile top-soil from land by wind or water is called soil erosion. Soil erosion does not occur easily where the land is covered by vegetations. Soil erosion is caused mainly by the large scale cutting down of forest trees and other plants. Large number of trees is cut down for obtaining wood for burning as fuel for building purposes and the manufacture of paper. When the forest trees and other plants are cut down then the top soil gets exposed and becomes loose which causes soil erosion.

The soil erosion could be prevented by preventing large scale cutting down forest trees and by afforestation of large number of plants and trees.

Steps to prevent soil pollution:

1. The use of polythene bags should be avoided to prevent soil pollution. It could be done by using bags made of paper, cloth or jute.
2. Where ever the plastic objects are used should be sent to factories for recycling to prevent soil pollution.
3. The use of pesticides in agriculture should be minimized to avoid soil pollution.
4. The use of excessive chemical fertilizers should be avoided to avoid soil pollution.
5. The emission of gases like sulphur dioxide and nitrogen oxides from the factories which causes should be controlled as maximum.
