Mike Keen is a professor of sociology at Indiana University South Bend as well as director of IU South Bend’s Center for a Sustainable Future. He also has served as a co-chair for South Bend Mayor Stephen J. Luecke’s Green Ribbon Commission. Mike is well-known and respected for his work and knowledge in the area of green initiatives and sustainable practices. I recently sat down with Mike to discuss the latest and greatest in how to build “green” and sustainable cities.
