Every drop for sale

It is said that:

As oil was the crisis of the twentieth century, water is the crisis of the twenty-first. Less than .0008 percent of the total water on earth is fit for human consumption, but global consumption of fresh water is doubling every twenty years.

A dramatic gap exists between those who have adequate water for survival and those who don't, and tensions over water in some areas of the world hover just below open war.
