ENV 210 offers an introduction to the scientific and technological dimensions of the nexus of global environmental problems: climate change, the carbon cycle, biodiversity loss, and the provision of food and water. The course will provide the scientific foundations to understand each of these complex environmental problems, first in isolation and then in its interaction with the others. Students will be able to understand major scientific reports on the interacting environmental challenges and assess their possible future trajectories, their potential solutions, and their implications for a growing human population on a finite planet.
