​Stephen Pacala developed a new undergraduate Environmental Studies course, ENV 200 A-F “The Environmental Nexus”, to examine a collection of global environmental crises. “When today’s undergraduates reach the peaks in their careers,” said Pacala, “four global environmental problems involving our climate, food, biodiversity, and water will also approach their peaks. The world will need to deal with the environmental nexus of climate change, biodiversity loss, and challenges to our supplies of food and fresh water.” This new course will address multiple dimensions of the issues, including scientific, political, social and ethical aspects and will be accessible to all majors and classes.
