One of the important element which keeps the life going on this earth is oxygen. The life-supporting oxygen is the product which we receive from the trees. Hence, trees are the basic manufacturer of oxygen which helps to grow life on Earth. Since last century there has been immense cutting down of the trees for different uses. The man has been cutting trees so as to make the life easy. In this run, the man himself has become the cause of his downfall. Trees purify the air and help in keeping the atmosphere cool. Cutting down of the trees has encouraged global warming which is a global concern. A rise in temperature has been noticed which is not a good symbol for life on Earth.
