How to make Shenzhen more beautiful
Shenzhen is a wonderful city. Many people visit it every year. It is a nice place to live in. But there are many kinds of pollution.
First, people throw rubbish everywhere and it makes the land very dirty. Second, many factories produce much waste. It pollutes the river and kills many fishes. It also pollutes the air. So we must take action at once.
First, we should throw less rubbish and put rubbish into the rubbish bins. Then, we should plant more trees. We shouldn’t cut down trees and destroy them. After that, we should not put dirty water into rivers. At last/Finally, we should use public transport.
I think Shenzhen will be more beautiful if we can take these actions.
