Saving Our City
It is important to deal with the rubbish in cities.Rubbish must be treated properly.Otherwise it may cause a lot of problems.It may pollute the air and water.When people breathe the polluted air or drink the polluted water ,they may get iii.
Our city has begun to pay attention to the problem.As far as I know ,some rubbish is sorted and sent to different factories.Rubbish ,such as old newspapers and glass ,is recycled.
Some harmful rubbish is sent to a 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.We should do our best to take good care of the environment and fight against pollution.
