Do trees have legal rights? What risks to the environment should we legally try to control or prevent? In this updated edition of Green Justice, the authors further explore the interrelationship between the legal system and the environment, using key environmental law cases (over half of which are new selections) on such topics as population and biodiversityand as recent as 1990. The authors liberal arts approach leads to a wide spectrum of related topics: the history of the common law, the political science of administrative agencies, our obligation to future generations, and the ecology of species extinction. With the help of explanatory introductions, study questions, and references to relevant literature, students are challenged to determine for themselves how the cases should have been decided and how they link up to broader issues. This accessible text is ideal for undergraduate courses in environmental law and environmental policy as well as nonlaw graduate courses in planning or public administration.
