"In the history books the 20th century will go by many names; the American century, the Nuclear century, the science century. The 20th century could also be called the oil century. When it was discovered that oil could be used as fuel and in various industrial applications, the once low substance became a vital resource over which wars were fought and lands conquered. The 21st century will likewise go by many names, and one of those names could well be the “water century,” as nations may find themselves embroiled in state-to-state wars and internal civil wars over access to water supplies.
An exploding human population is straining all of the Earth’s resources, none of them more important than water and by 2025 as many as 2.5 billion people could be facing “water based” vulnerability. And with the human population expected to peak at 10.5 billion in 2050, ensuring a stable, safe, and sustainable supply of water is becoming essential.
While water covers about 73 percent of the Earth’s surface, less than 3 percent of that water is fresh, and much of that is now polluted. The importance of water cannot be underestimated. Just look at your own body, about 60 percent of it is water. Further, a healthy person could survive a month or so without food, but few people could survive more than 3 or 4 days without water..."
