What happens if we don't have fresh water?

Our global water supply is becoming more of an issue every day. Even in developed nations, where a plentiful supply of water is sometimes taken for granted, the value of water is in­creasing among the people and their governments. This is important, because the planet is in the midst of what the United Nations is calling a "water crisis." For some people, the issue isn't a lack of water, but a lack of clean water: Millions of people die each year from preventable diseases, after drinking water from an unsanitary source. In other regions, water is simply scarce.A water shortage can affect you no matter where you live in the world. It's arguably humanity's most vital natural resource. It sustains all other activities; it's the essential basis of economies, societies and human life.­ The current crisis results from a combination of factors, but one rises above the others: the global population boom (swimming pool). As populations grow, so too, do their demands on water. People must be fed, and agriculture must have water to grow crops and livestock. This puts a demand on naturally available water. Don't think that we haven't got the water shortage in the world, most of our human cousins are already suffering the water shortage such as some places in Indonesia and Africa. Its notable that water can't be created and water are also got their own cycle called water cycle which is what caused the rain.
