The pollution
①One third of the world's people don't have enough clean water.
②More and more diseases are caused by polluted air.
③People are disturbed quite often by kinds of noises.
④Every person in our city makes about 1.8 kilos of rubbish every day.
The environment is becoming worse and worse.There are many kinds of pollution I worry about.The most serious two are water pollution and air pollution,because people can't live healthily with dirty water and polluted air,nor can animals.More and more diseases are caused by polluted air.
I think factories should not pour dirty water into the river directly or produce more waste gas.We'd better go on foot or by like instead of by car,because more cars mean more waste gas.We should make our world more and more beautiful.
污染
①世界上三分之一的人没有足够的干净的水。
②越来越多的疾病是由空气污染引起的。
③人受到各种噪声的干扰，常常。
每个人在我们的城市④约1.8公斤每天的垃圾。
环境变得越来越糟。有很多种污染我担心。污染最严重的是水污染和空气污染，因为人们不能健康地生活在肮脏的水和污染的空气中，动物也不能健康地生活。越来越多的疾病是由被污染的空气造成的。
我认为工厂不应该直接把污水倒进河里或生产更多的废气。我们最好是步行或乘汽车，因为更多的汽车意味着更多的废气。我们应该让我们的世界变得越来越美丽。
