Water pollution is among one of the most concerning problem facing the world today. There are some ways to overcome this problem. Firstly, we have to turn off the water faucets when we don't use them. Secondly, we have to reduce the amounts of rubbish which is thrown into the river. This is important because rubbish is the main reason that causes water pollution. Thirdly, we have to use water for the right purposes. An example, we can use water for doing housework, farming but we mustn't use water to play some pointless games such as playing gun water, throwing water balloon... Finally, we can make use of rainwater, because rainwater is natural sources. We can use rainwater to have a shower instead of machine water. To sum up, water plays an important role in our life, we should reduce water pollution as much as possible.
