Firstly, an effective way, I think, is to reserve water in a scientific way for future use .Secondly, new methods need to be developed to use the existing water resources ,for example, turning sea water into fresh water. Thirdly , we must stop water pollution by law. Last but not least, it’s everyone’s responsibility to make good use of water ,such as recycling and saving water in our daily life.
In conclusion , people around the world should be ware of the real situation of water shortage, protect the present water resources and explore potential ones scientifically .
