Forests are a valuable resource that nature gives to humans. However, forests are also a limited resource, so we must know how to exploit them properly. Forests have many important roles for people, provide shade, oxygen, water retention, flood prevention. When we exploit a forest tree, it is also time to immediately plant a new forest tree for it to develop and promote its role. If we can't do that, and people keep deforestation, one day we'll have to pay a heavy price.
