It is very important to deal with the rubbish in cities.Rubbish must be treated properly,

otherwise it may cause problems.It may pollute the air and water.If people breathe the pollute

d air or drink the polluted water, they may get ill.

     Our city has begun to pay attention to the problem.For example, rubbish is sorted.Some

rubbish, such as newspapers and glass, is recycled.The rest, which is believed to be harmful,

is sent to a certain place and buried.Laws have been passed to protect the environment, so

waste water should be treated before it is poured into rivers.

     We've been trying, but there is still a long way to go.After all, if everyone did his part to

help fight against pollution, we could all share in a cleaner and more beautiful world.
