This book would be a good introduction for someone interested in learning more about sustainable food systems and conserving water use by selecting the right foods, but it doesn't come away with practical tips on reducing water use in the kitchen in the way that the book's look and marketing may make you think. 

Additionally, many of the chapters seem to repeat other chapters because at certain points there's not too much new information (the chapters on chocolate and coffee were very similar). Also, the point of the book kept coming back to focusing on using organics, which overall is very frustrating, as that's not an accessible solution for most people. 

Regardless, as I said, I think this book would be beneficial to someone who hasn't had any experience in sustainable food systems!
