People have plowed up, cut-down and otherwise heavily manipulated more than 75% of the world's forests and grasslands, releasing roughly 30% of the carbon in the atmosphere added by people. In the next 30 years, the world is on a path to convert vast additional areas of forest and diverse habitats to meet rising demands for food, wood, and energy. This course will explore the scope of the challenge and possible solutions. Students will obtain a general understanding of important scientific concepts, such as the carbon cycle, basic principles of agronomy and biodiversity. They will also explore a wide range of policy issues.
