Erban Cowboy is a strip we wrote for the Monroe Street Journal (MSJ), a weekly business school newspaper at the University of Michigan. Erb is short for the Erb Institute for Global Sustainable Enterprise, a dual-degree program where students graduate with both an MBA from the Ross School of Buisness and an MS from the School of Natural Resources and Environment.  We had multiple objectives in this strip: to get fellow students to think about sustainability issues (without preaching), to spread the word about our program, and of course, to be funny.
