保护我们的城市
It is very important to deal with the rubbish in cities. Rubbish must be thrown away or reused properly. Or it may cause a lot of problems. It may pollute the air and water. People may get ill when they breathe the polluted air or drink the polluted water.
Our city has started to face the problem. Some rubbish is sorted and sent to a certain place .Waste gas is cleaned before it goes into the air. Waste water is also cleaned before it is poured into rivers.
People should be prevented from throwing rubbish everywhere. We should try our best to take care of our environment and fight against pollution.
