Two of the biggest challenges humanity has to face - promoting human health and halting environmental degradation - are strongly linked. The emerging field of Planetary Health recognizes these inter-linkages and promotes creative, interdisciplinary solutions that protect human health and the health of the ecosystems on which we depend. Through a series of lectures and case-study discussions, students will develop an in-depth understanding of the 'Planetary Health' concept, its foundation, goals, priority areas of action, methods of investigation, and the most relevant immediate challenges.
