Usefulness of Trees
Trees are very useful and beautiful gift of nature. They maintain the balance of oxygen and carbon dioxide and let off oxygen without which we cannot live. Thus they purify our environment from air pollution. They stop the advance of deserts. Trees do a lot of good to men. They give shelter and food to us. Travellers take shelter and rest in the cool shade of trees when they get tired. We get rubber, medicine, wood for furniture, honey, gum, wax, etc from trees. Forests bring clouds and clouds bring rain. Rain helps us to cultivate land and produce food. So we should save trees, our best friends, for our own interest.
