let's clean-up the neighborhood

Dear Ai,
I am very pleased to hear that you and your family are fine. In the last letter, you asked me what we should do to protect the environment in our area. I have thought a lot about it and found out some solutions.

The first measure I think is to hold a ''clean-up" campaign in the neighborhood. As you see, nowadays, paths, rivers and lakes are covered with garbage which not only smell unpleasant but also do harm to our health. So it is important to have someone voluntarily clean up the area regularly and also plant more trees for fresh air.
