This course examines the ways domestic US and international environmental regulatory frameworks adopt, interpret and otherwise accommodate scientific information. The course focuses on several case studies, that provide insights into the science-policy interactions which emerge from managing natural resources and environmental risk. Topics include air pollution; climate change; ozone depletion; managing the world's forests, fisheries, and ecosystem services, and global trade in wildlife. Students will explore the science underlying these issues as well as current policies and the range of future policy responses.
