I received a free copy of this book in exchange for an honest review. 

This is absolutely the best and most helpful environmental books I have ever read. Unlike other books in the same category, A Pocket Guide to Sustainable Food Shopping shows the systemic impact involved in environmentalism, but lets the reader know their efforts aren't futile. It's broken up in very consumable chapters that cover any aspect of food shopping someone could think of. It's a very unbiased book that shows evidence-based truths and pushes the reader to think critically. I suggest anybody interested in sustainability and environmentalism reads this book.
