People in my hometown used to live in old buildings.The rivers were clear and many fish were swimming happily.The houses were old and streets were narrow.People worked in the farmland.
Now there are spacious buildings in my hometown.A lot of people have their own cars.But many trees have been cut down and rivers have been polluted.Fish are extiguishing.Our government should take some measures to protect the environment and people should have the sense of environment protection.
