We should plant trees and nurture the ones already present in the neighbourhood. Why?’
Answer:
Trees make their own food from carbon dioxide (C02) in the atmosphere, water, sunlight and a small amount of soil elements. In the process, they release oxygen (02) for us to breathe. Thereby maintaining the carbon dioxide level in the atmosphere. This prevent global warming. Trees purify the air and reduces air pollution.
