In clear and accessible language, Gruen discusses a range of issues central to human-animal relations and offers a reasoned new perspective on key debates in the field. She analyses and explains a range of theoretical positions and poses challenging questions that directly encourage readers to hone their ethical reasoning skills and to develop a defensible position about their own practices. Her book will be an invaluable resource for students in a wide range of disciplines including ethics, environmental studies, veterinary science, gender studies, and the emerging field of animal studies. The book is an engaging account of animal ethics for readers with no prior background in philosophy.
