Water is becoming an increasingly important issue in the developed world. But this issue is nothing new for other, less developed nations. For centuries, clean drinking water has been hard to come by for many populations, especially the poor. In some areas, water may be available, but it’s often disease-ridden, and drinking it can be fatal. In other areas, a viable water supply is simply not available at all.
A 2006 United Nations report estimated that as much as 20 percent of the world’s population doesn’t have access to clean drinking water [source: BBC]. This leads us to wonder: If we need it so badly, why can’t we just make it?
