The main cause of the total destruction of vegetation is the pollution of soil. This leads to erosion, which makes it difficult for plant roots to hold on to the soil. In addition, heavy metals and other chemicals in the soil also suffocate plants as they enter through their roots.
The use of pesticides is another cause that causes vegetation destruction. The pesticide can bring about side effects such as spraying chemical residues from field to field, which can kill all vegetation by breaking down plant cell walls.
