The saying "Do not let our tear be the last drop of water on our earth" has become a catch phrase nowadays and it is a well-known fact that there is a shortage of fresh water on our planet. In some areas of the world, fighting for fresh water has led to serious conflicts between different nations. This testifies to the fact that the scarcity of fresh water has turned to be a serious global problem.
Scarce as it is, there are still people who waste the fresh water that is vital for the very existence of the human beings. With the rapid development of the economy and the explosion of the population, fresh water has been consumed at a much faster pace. Meanwhile, water pollution has been an increasing concern for many of us. Then is there a way out
As far as I’m concerned, the government should give priority to the protection of our water resources. At the same time, we need to step up our efforts to research and develop technologies to recycle waste water and convert sea water into drinkable fresh water. Only through combination of all efforts can we deal with the problem well.
