Answer:
Oxygen
It is the most important part of our life. It helps us to live. Why teachers say to not to cut the trees because trees are the only who takes carbon dioxide and give us oxygen. And if cut more and more trees then we will not be able to get oxygen and oxygen, that we inhale will lost then not only the mankind all the animals insects will die.
And we people cut trees and taking them to the road of death. So from now we should plant trees as much as we can do.
