We should not cut trees in excessive. We should take something from nature and return it too. Like we should plant many number of trees. Also we should cut dried up trees and not the green ones. As it is always said, "Nature has enough to fulfill our needs and not our greeds". We our exploiting our forests and wood. We have to cut trees for many things but we should also see that we are cutting only as much as we need and not more than that.
