Trees are very useful to man. They support the life of living beings. The green leaves of absorb carbon dioxide and break it up into carbon and oxygen.
Thus trees replace oxygen which is constantly used up and changed into carbon dioxide in breathing and burning. The trees retain carbon and release oxygen for the use of living beings.
Trees help to prevent drought and floods. Man has not recognised the importance of trees. Man cuts down trees to get quick profit from them. We should plant more and more trees.
We should not cut them down. Man can live a happy life only if he plants more trees. We can inhale fresh air if we have more trees on this earth.
