Afforestation is the effort to plant trees in barren lands so as to create a new forest. In simple words by planting trees and creating forests, many of the commercial needs of human beings are fulfilled Afforestation is, therefore, a practice that has been propagated in many countries as a way to stop over-exploitation of nature.
With increasing demand for fuel woods and building materials, afforestation helps to meet these demands without cutting down natural forests.
Afforestation will also lead to proper rain in all regions and help in prevention of underground water which is a natural resource. Also large number of trees will absorb more amount of carbon dioxide in photosynthesis process hence reducing air pollution and conserving clean air.
