In this class, students will tackle challenging questions about security and the environment, and examine definitions of "security" relating to the natural world such as food security, water security, energy security. Case studies will address the complex relationship between natural resources, war and conflict, and national priorities. We will also look at the tension between national security and environmental protection. The impact of climate change on all types of security will be a central focus. Students will be evaluated based on written reflections, two exams, and several quizzes, as well as participation in regular class discussions.
