With the acceleration of urbanization, city waste problem is getting worse. Rubbish must be treated properly, otherwise it causes trouble. It pollutes the environment and is harmful to our health. If we breathe the polluted air or drink the polluted water, we may get ill. Therefore, I am writing to you to voice my opinions.
In my opinion, it is about time that we dealt with the rubbish in cities. Rubbish must be sorted. Some, such as newspapers and glass, can be recycled. The rest, which is believed to be harmful, should be sent to a certain place and buried. Laws have been passed to protect the environment, so waste water should be treated before it is poured into rivers.
We’re been trying, but there is still a long way to go. We should do our best to fight against city rubbish.
