This essay explains the author's approach to teaching environmental ethics in the graduate school of business. The approach is based on a religious rather than a philosophical perspective, taking its light not from theology or religious studies but from anthropology. The author discusses the origins of the course, then explains the anthropological model of religion as a cultural system and briefly applies that model to economics, focusing on the worldview that undergirds it. The course then shifts to how others understand the world in which they live, introduces Aldo Leopold's A Sand County Almanac, and ends by speculating on what might come next if the course were a third longer than it is.
