It is no longer possible to separate the health of the planet from the health of its people. Disease patterns are changing as the climate does, and human health is at risk from loss of biodiversity, depleted water supplies, environmental toxins, and collapsing food systems. As the Rockefeller Foundation-Lancet Commission on Planetary Health states: “The continuing degradation of natural systems threatens to reverse the health gains seen over the last century… We have mortgaged the health of future generations to realize economic and development gains in the present.” Do we have the scientific knowledge and political will to approach these systems differently?
