Crisis before we look for reasonable solution. But looking at the whole picture, looking at the whole picture of the river helps us understand yes, why we exist the way we do here in the southwest. It also helps us understand the role of rivers surface water in arid regions, and other parts of the world. But it also gives us a larger picture, a piece of a larger picture of how humans relate to the environment and the stresses and strains that come along with it or the political fights that hamper, creating a sustainable relationship, all of the barriers that stand in the way of making better use of our natural resources.

I think it would be a fabulous example for river watersheds throughout the world. For more information on all of the cities visited by booktvs local content vehicle, visit us online at cspan.
