They take in greenhouse gases like CO_2 and produce oxygen. This means they help create a clean environment for everyone on this planet.$
Trees make our lives more convenient. Many of the things around us, such as paper and pencils, come from trees. Just look around your room—a lot of the furniture is made of wood. Trees also provide us with delicious fruit and wonderful drinks. For example, we can make tea from the leaves of the tea tree.
