It is important to deal with the rubbish in cities. Many citizens who unaware of the importance of protecting the environment throw away their rubbish in a way unfriendly to the environment. Rubbish must be treated properly. Thus, it may cause a lot of problems. It may result in the air and water is polluted. When people breathe and drink which has been polluted, we will get ill.
To our happiness, our city has begun to pay attention to the problems. As far as I know, some rubbish is sorted and sent to different factory. Rubbish, such as glass and old newspapers, are recycled. Some harmful rubbish is sent to the certain place and buried. Waste air is cleaned before it goes into the air. Waste water is treated before it is poured into rivers. To protect the environment, the government has passed laws to prevent people from throwing rubbish everywhere, made our city much cleaner than before. As individuals, we should do our part to fight against illegal actions at anytime we find them.
