篇四：保护我们的地球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.
but that's not enough. we must all try our. best to prevent rubbish from polluting the environment so as to. save our city and our living place.
