"These are unexpectedly deep and moving conversations about where we can go, and where we must go, both as individuals and as a planet. This book is a hardheaded account of the sacredness of the earth, and what that implies for our work and society." Bill McKibben, author of Eaarth: Making a Life on a Tough New Planet "John Ehrenfeld's thinking about our species and our place in the world is indeed a thing of beauty, as Andrew Hoffman's intelligent dialogue with him brings out on every page." James Gustave Speth, author of America the Possible: Manifesto for a New Economy "This is a deeply illuminating conversation between two sustainability thought leaders on whom I wish I had been able to eavesdrop. Now, happily and inspirationally, we all can." John Elkington, Co-founder of ENDS, SustainAbility and Volans, and author of The Zeronauts: Breaking the Sustainability Barrier
