This is an excellent and enlightening work about the general state of the planet, humanity as a species, where we belong on the planet and what it means to us in terms of sustaining us as a species for the long run. Well-written and divided into chapters which could be summarized as humanity, air, earth, water, fire, community, love, spirituality and balance, this book paints an accurate state of the world picture with facts as well as metaphors. It always presents its concern about the greater picture without losing sight of the details. A great balance of general science and spirituality, with just enough facts and personal stories of many to make the points convincing, this book also is threaded with impacting and eye-opening quotes and poetry from a variety of sources and people. A superb book, overall, from someone who has seen a lot of what he wrote about. This book should be on the curriculum for senior year high school so that the future generations can get a good grasp of the world as they become contributing adults in that world which they will own and determine, more impacting than ever, for future generations. No matter how much or how little they will get from it, every bit helps at a time when that is truer than ever in the past from every one of us living today. Don't get me wrong, though, it's not the book that's profound. It's what you do with what you learn from it which will be.
