We hardly ever think about water -- it's just there. Until it isn't, and then what happens? Author looks at several situations in which water supplies have dwindled and the responses from the public, the politicians, businesses, and other interests. One of my favorite parts of the book discusses how people in rich countries spend huge amounts of money for bottled water that is likely not as pure as their own local tapwater, but you can't beat good marketing! Also, since water can't be created or destroyed and it has been on earth billions of years, every molecule of the purest water you can buy has seen the insides of many a dinosaur before being held up as an icon of purity! I like that the book is different for me, and makes me look at the water everywhere around me in a different way.
