What is the best Green Degree?

I'm interested in studying environmental design, but I'm unsure about a major. I'm interested in Urban ecology, Industrial/urban/environmental development and design (large and small scale), and sustainable business. Any suggestions on programs/schools/majors that would make the best use of the progress the green building movement is making. Not only would I be interested in building from scratch, but really updating exisiting homes and businesses to be more environmentally mindfull. Something like the Green Bakery a href="http://www.buildagreenbakery.com/..." rel="nofollow"http://www.buildagreenbakery.com/.../a where all aspects are considered.
