Everybody knows that there is serious problem of water pollution on the earth. Yes, water pollution is increasing.

Look! The water in the river is getting dirtier and dirtier. Most of fish in the water have died, and we can't swim in the water.

My grandfather says, when he was very little, the water in the river was very clean. He often swam in the river with his friends.

That was before, but now we can't see such clean rivers. Let's protect the water from pollution, because we can't live without water. The water is really important to us all.

大家都都知道全球水污染是一个严重的问题。是的，水污染正在加剧。

看！河里的水越来越脏。水里的游鱼大部分已经死了，我们已经不能在水中游泳。

我的祖父说，在他很小的时候，河里的水很干净。他经常和朋友一起在河里游泳。

那是以前，但现在我们看不到这样清澈的河流。让我们保护水资源免受污染，因为我们不能没有水，水对我们真的很重要。
