Query: A must-read...

Erik Marcus hits the nail on the head with this book. As a vegetarian making the transition to veganism, this book not only answered my questions about veganism (such as, will I get enough calcium?), but it also re-enforced my reasons for choosing to go vegan in the first place: to do my part in healing the planet. I applaud this book and I encourage anyone who cares about either the environment, animal welfare, their own health, or even weight loss to read this book.
