Dear citizens,
We are a group of students in a middle school. We find that many trees in our city have been damaged. Trees are our good friends. They clean the air and bring us enough oxygen. They help keep the balance of nature. The green leaves and the different gestures of the trees add beauty to our city. With trees,many birds come to our city. They make our life vivid and interesting. We should protect the trees. Now we are calling.Don't hurt our friends -- trees.
A group of students
