Question
Explain the significance of Afforestation.
✓
Answer
Afforestation helps the wild animals and even humans to have shelter and to find their food source.
Through afforestation we can increase the supply of oxygen. Trees planted can increase the water vapour in the atmosphere to get the rainfall.
By planting trees the amount of carbon dioxide in the atmosphere can be reduced and thus the effects of air pollution, green house gases and global warming can be controlled.
Afforestation enables us to avoid desertification of land.
Barren lands experience strong winds and it causes soil erosion. Top soil is washed away during rainfall. Afforestation helps to grow more trees so that they can hold the top soil along with the nutrients.
Creating forests provides us fodder, fruits, firewood and many other resources.
Industries need specific type of trees. Afforestation helps us to grow a particular type of trees.
