Earth systems science reveals that the environmental conditions that supported the development of human civilization over the past 10,000 years are becoming increasingly destabilized. This course introduces students to the Earth's regulatory systems such as climate, nitrogen and phosphorus flows, forests, oceans and biodiversity, and the social structures and processes that are interfering with them. Students will come to understand that environmental problems cannot be solved by individual behavioural changes; solutions will require collective action to achieve systemic change.
