"This is a gritty and challenging text: it marks out a distinctive philosophical position that merits serious attention by environmentalists and animal rights supporters alike."--Animal Welfare"In Nature's Interests? provides a valuable addition to the literature on moral considerability. Varner is a must-read for any serious environmental philosopher, and this book would be a welcome addition to any graduate seminar in the field. At the same time, however, the book is accessible to nonacademics with a serious interest in the subject since Varner's creative examples...and clear writing provide an excellent complement to his scholarship."--Ethics and the Environment"All libraries supporting curricula in environmental ethics should own it....Varner knows his field, including the relevant literature, and argues using logic and the tools of philosophers. He examines opposing views fairly. He also knows his biology well. Well written and mercifully short."--Choice"The book is a pleasure to read. The author is unduly influenced neither by radical nor conservative environmentalist camps. He has a mind of his own."--Environmental Ethics"This is a brave and ambitious book. It is densely argued and beautifully written."--The Philosophical Review
