Water is one of the most basic of all needs - we cannot live for more than a few days without it. And yet, most people take water for granted. We waste water needlessly and don't realize that clean water is a very limited resource. More than 1 billion people around the world have no access to safe, clean drinking water, and over 2.5 billion do not have adequate sanitation service. Over 2 million people die each year because of unsafe water - and most of them are children!
