Welcome! I'm a professor of philosophy at Colorado State University in Fort Collins, Colorado. My main research interests center on environmental ethics, consumption and population issues, and wild lands preservation. I'm the author of Thoreau's Living Ethics: Walden and the Pursuit of Virtue and co-editor with Eileen Crist of the recently released anthology Life on the Brink: Environmentalists Confront Overpopulation, both published by University of Georgia Press. I am an affiliated faculty member of CSU’s School of Global Environmental Sustainability and president of the International Society for Environmental Ethics. I live in Fort Collins with my wife Kris and sons Henry and Tom.
