Dr. Richard Oppenlander introduces the idea of global ecological depletion in terms of food and food-choices. He presents an understanding of sustainability that complicates simplistic metrics and definitions, demanding a more holistic approach in our choices. To this end, he structures the book as "more of a symphony than a conventional nonfiction book," presenting information that contextualizes further chapters. After introducing the ideas of sustainability and global depletion he wants to explore in the book, he turns to areas of depletion (rainforests, land, water, oceans, etc.), and finally to an account of how depletion arrived at the crisis point and what we can do about it. He provides the facts and an appreciation for their gravity. His focus is on food-choices because food is what links us all together. Annotation ©2013 Book News, Inc., Portland, OR (booknews.com)
