Pathways to Planetary Health, the Garrison Institute’s signature environmental initiative, informs the emerging field of Planetary Health with the exploration of ethical responsibility that comes with the human intervention into the health of the earth’s systems, and the pathways that can return us to planetary health. This initiative builds on the Garrison Institute’s nearly two decades of experience convening experts to develop practical, scalable solutions that integrate moral, ethical, and behavioral insights and make a real impact on communities and systems.
