Dear Editor,
In some places in our country the surroundings is worsening with the air filled with heavy smoke, many mountains turning deserted and rivers polluted. Waste is scattered here and there.
So I strongly suggest that government take effective measures to stop this. First more laws should be passed to protect the surroundings. Factories are forbidden to send out smoke and poisonous gases into the air. Every year more trees should be planted on the mountains, No one is allowed to cut down any trees or pour waste water into the rivers. Anyone who breaks the law should be punished accordingly. Secondly the public should be clear that it is a shame to throw rubbish around.
All people should fore1 good habits to protect the surroundings.
Only when the whole society takes actions, will the sky become blue, mountains green and rivers clear. Thus our home will become more beautiful.
Yours truly
Li Hua
