The earth is the homeland where we live.Once upon a time the air was so fresh and the earth were covered with green trees.But with the development of industry,Our environment is not as beautiful as before.
The air is polluted by factries and cars.Too much noise is produced by them.Many rivers are also polluted by waste water.People have to drink the poluted water which is bad for our health.
Now we must take some measures to prevent the earth from being polluted.Stop the factries from produing more waste water.We sholdn't use plastic bags any more .Plant more trees to make our air clean again.
