My book club just added this book to our yearly list. A readable on water, waste and need. Two Colorado Rivers, this one along the West coast. Building of Boulder (Hoover) Dam, the use of water as well as how farming in the desert may not be the smartest thing we humans have done. Also talks about how the measures taken to conserve actually allow for more building and farming. The Colorado no longer reaches the ocean and so salty that much is unusable. Without water we die, learn as much as you can to preserve this natural resources.
