The need to save the trees is that when you cut all the trees and plant new ones, they will take a lot of time to grow into a full grown up tree, till then who will provide us with oxygen in a sufficient manner and we produce carbon dioxide on respiration the if there will be no trees then global warming will increase which will become a dangerous threat to us.
