Marquette University’s new Interdisciplinary Minor in Environmental Ethics moves beyond a multidisciplinary approach to learning by integrating and applying the knowledge and skills acquired in ecology, natural resource economics, environmental philosophy, earth physics, and theology courses. The first two years of this interdisciplinary program provided an opportunity for faculty and students to experiment with collaborative methods in their individual courses to integrate their efforts in a capstone seminar that focused on the ethical implications of electricity generation and use in the United States. From this experience, a more comprehensive approach to addressing environmental problems from an ethical perspective was developed, and more effective ways of teaching and learning were identified to improve the program.
