Second, it can make our cities more beautiful. With trees and flowers everywhere, living conditions can be improved. Finally, it can produce timber----an effective way to solve the problems of limited supply of natural resources.

　　 Making our cities greener requires nationwide efforts. People in every field should not only know about the importance of keeping the quality of urban environment, but also take common action to plant more trees and flowers so as to improve our living conditions.
