Forests are very important to human beings. Now in some parts of our country, many people have been cutting down trees in the forest because they need wood and more farmland. Protecting forests and timber is very important to us. I think the best way to protect them is to plant more trees. In our life, we should use less paper and pencils. We can send emails instead of greeting cards. In my opinion, we should realize the importance of forests. We should try our best to protect our living environment and keep mountains green, water clear and sky blue.
