The choice of whether or not to consume animals is more than merely a dietary one.  It frequently reflects deep ethical commitments or religious convictions that serve as the bedrock of an entire lifestyle.  Proponents of vegetarianism frequently infuriate nonvegetarians, who feel that they''re being morally condemned because of what they choose to eat.  Vegetarians are frequently infuriated by what they consider to be the nonvegetarians'' disregard for the environment and animal-suffering.  

Vegetarianism:  A Guide for the Perplexed offers a much needed survey of the different arguments offered by ethical vegetarians and their critics.  In a rigorous but accessible manner, the author scrutinizes the strengths and weaknesses of arguments in defense of vegetarianism based on compassion, rights, interests, eco-feminism, environmentalism, anthrocentrism, and religion.  Authors examined include Peter Singer, Tom Regan, Carol J. Adams, and Kathryn Paxton George.

As the global climate crisis worsens, population increases, and fossil fuels disappear, ethical and public policy questions about the ethics of diet will become ever more urgent.  This book is a useful resource for thinking through the questions.
