Professor John Wargo introduces the central question of the course, "Can law shape a sustainable future for ten billion people?" The purpose of the course is to examine the most important U.S. laws adopted over the past forty years, and to evaluate their effectiveness. Lectures will present histories of nuclear experimentation, industrial and organic agriculture, air quality, plastics, wilderness, green building certification, and land use regulation. By the end of the course students will be exposed to diverse statutory and regulatory strategies to prevent pollution, reduce wastes, protect human health, conserve energy, and to protect wild lands.
