Water is very important for us. We can’t imagine life without water.There will be no trees, no animals and even no people if there is no water. But now many rivers and lakes are polluted. So, what shall we do ? We can do like these things:
First, we can stop the factory form pouring waste water into the river.
Second, we also can stop people from throwing litter into the river.
……
Finally,we can tell the people how important the water is.
After doing these things, I think water will become cleaner and cleaner !
