My hometown is just like a mother to me who is absolutely gentle and careful. She was very beautiful with green trees and brushes, tidy and clean stream and fish. At the same time, the buildings are very simple and shabby and the streets and roads are narrow. But now everything is changed. With the rapid economical development, as far as eyes could see is the tall bulidings, shops, and cars. However, the issue of pollution is serious too. Trees and fish are disappearing. Thus, it is necessary to fix the pollution.
