World Water Day is celebrated on March 22 every year.It draws attention to the important role of water in our lives，the difficulties people face in getting water and solutions to these problems.It is reported by scientists that between 55 and 60 percent of the adult body is made of it.In normal conditions，the human body can only stay alive three or four days without water.We need water to stay alive，yet there are billions of people all over the world who do not have access（使用） to safe drinking water.
    The problems facing communities without water
    Except for the obvious health problems，a shortage of clean water means that some people in some areas—often women and children—have to spend hours every day walking to and from distant water supplies（供应）.This means they don't have time to focus their attention on their work，studies and other duties.So the search for water becomes their main jobs.For many people，the access to water has become increasingly difficult because of the increasing need for a limited resource.
    What are the solutions？
    In fact，many governments and organizations have already taken actions to offer good solutions.Waste- water recycling，storing rainwater，more efficient irrigation techniques（灌溉技术） and reforestation are good examples of how water can be used more efficiently.There are also many other charities working on creating sustainable（可持续性） supplies of clean water for different communities around the world，but this important work needs to continue.
    What we can do to help
    The theme of World Water Day is valuing water.The value of water is about much more than its price.Without an understanding of water's true value，we will be unable to safeguard it.What we can do to help is to support charities，take part in the World Water Day events，be careful with how we use water in our own lives. 'We can also visit the UN World Water Day website to find out about an event near us and help spread around the world about the importance of saving water.
