With the rapid development of cities, a new problem has emerged recently. There is a huge amount of city rubbish, which cannot be handled appropriately in big cities. Citizens throw away a lot of rubbish daily, and there is not enough space to dump it. As a result, the environment is polluted.
There should be several ways to deal with this problem. First, some of the rubbish can be reused after a proper treatment, for example, waste paper, bottles, metals, etc. People in the city should be told to classify their rubbish and the city government should collect the rubbish on time. In this way a large amount of rubbish can be retrieved, and reused. Second, some kinds of education should be carried out among the city people on not littering the rubbish and on the importance of protection the environment.
By accepting the two suggestions mentioned above, the wastes can be made full use of and the city environment can be well protected.
