David W. Orr is the Paul Sears Distinguished Professor of Environmental Studies and Politics Emeritus at Oberlin College, and presently Professor of Practice at Arizona State University.
During his tenure at the Environmental Studies Center at Oberlin College, Orr demonstrated how institutions of higher learning can teach ecological literacy while practicing sustainable design and encouraging more eco-friendly lifestyles on campus. Orr's books, Ecological Literacy: Education and the Transition to a Postmodern World (1992) and Earth in Mind (1994-2004), proposed ways in which education should evolve to emphasize sustainability, not only in the narrow parameters of ecology-based programs, but in wider curricula, from political science and economics to liberal arts.
