Solution

The correct option is C
afforestation

The problems such as flood, soil erosion, extinction of wild species and global warming can be reduced to an extent by the process of afforestation i.e. by planting more trees. The term should not be confused with reforestation, which is the process of specifically planting native trees into a forest that has decreasing numbers of trees. Afforestation is highly important to maintain biodiversity and ecological balances. It is important in purifying the environment and also helps in reducing the carbon dioxide level.
