Madeline Rogero, Director of the Community Development Department for the City of Knoxville, spoke to a record-setting crowd about the book Green metropolis : why living smaller, living closer, and driving less are the keys to sustainability by David Owen. Owen argues that the greenest community in the United States is not Portland, Oregon, or Snowmass, Colorado, but New York, New York. Residents of compact urban centers live in smaller spaces, discard less trash, and, most important of all, spend far less time in automobiles. (Recorded September 29, 2010)
