What does it really mean to be “sustainable”? Is this simply a feel-good term, or does it have measurable substance? Can economies grow while concurrently supporting a good quality of life for all? What can nature teach us about sustainable living?  Through selected readings, discussions, debates, films, and speakers, the concept of sustainability will be explored as both a goal and a process. Potentials and constraints for achieving sustainability from ecological, political, economic, social, and ethical perspectives will be critically examined. Methodologies for qualitatively and quantitatively measuring sustainability will be introduced, practiced, and critiqued.
