Also,there are some people who don`t pay attention to hygiene and they can`t stop littering the rubbish casually or spitting everywhere all the time.And in addition, there are a few factories often cutting down the trees, discharging chemicals and dirty water and so on.And it causes many problems like the Greenhouse Effect.If they do these day by day and our life will be harder and harder,so we have to stop them. To stop them we can put up commonweal advertisements and tell them the detriment of destroying the environment.So we can start from now to make a beautiful life.

　　如今，越來(lái)越多的人意識(shí)到它的`必要保護(hù)環(huán)境。同時(shí)，也有一些人不`不注意衛(wèi)生，他們可以`停止亂扔垃圾垃圾隨便或隨地吐痰的時(shí)候。此外，還有一些工廠經(jīng)�？撤�樹木，排放的化學(xué)物質(zhì)和臟水。這引起了諸如溫室效應(yīng)等問題。如果他們天天這樣做，我們的生活會(huì)變得很困難，所以我們必須阻止他們。阻止他們，我們可以把公益廣告，告訴他們破壞環(huán)境的損害。所以，我們可以從現(xiàn)在開始做一個(gè)美好的生活。
