it is very important to deal with the rubbish in cities. for one thing, rubbish may cause a lot of pollution. it may pollute the air, the water and the places we live in. for another, it may do harm to people's health.

so in our city, rubbish is well dealt with. first, it is sorted. then old newspapers and glass are recycled. the harmful wastes are buried and the waste water is cleaned before it goes into the river. the government has already made laws against pollution caused by rubbish.
