Planetary health is about the relationship between the health of the planet, and the health of people, who ultimately depend on the planet for survival of our species. This course will provide students with a big picture perspective of planetary health, research, policy and practice issues related to it, and the implications and opportunities related to planetary health for public and population health globally. A key theme throughout will be consideration of health and social equity issues and the differential impacts of climate and other environmental changes on populations in light of these issues.
