A well written, very well researched, and well organized book - but not as a good as Glennon's lean and mean Water Follies, which sets out the legal basis for water rights in the United States and its impact on unsustainable water use in the US Southwest. Unquenchable instead looks at the overall picture of water consumption in the US as a whole and offers ways to resolve America's untenable use of its finite and clearly dwindling water resources. Call it the water side of the equation to Michael Pollan's Omnivore's Dilemma, which Glennon refers to several times, and which I compare Glennon's work to favourably. Despite dealing with a difficult subject, Glennon's approach is focused and optimistic, seeing opportunities instead of unresolvable, wicked, problems. He also works very closely with the economic costs of water use, which is excellent, in large part because he suggests that the way to avoid depleting this common good is through market pricing. Though through a highly regulated market and specifically tailored process to each waterway and community that benefits all parties, as opposed to the death knell of privatizing water and allowing the invisible hand to resolve the issues. As he says, "Adam Smith's fallacy, to [economist Duncan K.] Foley, is that selfishness in the service of capitalist market relations helps our fellow human beings. This convenient rationalization allows us to ignore the harsh consequences of a cruel market, ranging from large-scale unemployment to environmental degradation to the destruction of cultures and communities." (pages 309-310) A very good book on the whole, but which should be read in conjunction with his Water Follies if you are to fully appreciate the nuances of how the United States' legal regime undermines water conservation and responsible use.
