The forest is the lungs of nature From the picture we can find there is a person in the forest cutting one of trees, meanwhile the man's head is being pecked by a woodpecker and there are some words in this bird's mind, there must be worms in this piece of the wood. I guess the drawer who made the picture want to tell us the person who deforest must be fool, that is, it is equal to suicide if no action to halt deforestation. As we know the environment plays a big role in our life. It is not only a resource pool but a doctor for every life on the earth. So we have the responsibility to protect the environment. The good old proverb "the forest is the lungs of nature "reminds us of the forest's significance. Indeed, it is critical to learn how to develop forest reasonably and how to protect it.
