The One health Concept
As defined by One Health Commission, "One Health is an approach that recognizes that the health of people is closely connected to the health of animals and our shared environment",
As well, in 2015 the Rockefeller Foundation and The Lancet defines Planetary health referring to "the health of human civilization and the state of the natural systems on which it depends"
One Health, as well as the Planetary Health concept, are rooted in the profound interdependence of human and natural systems: there is a significant overlap between planetary health and traditional environmental health; both examine the relationship between human health and conditions and exposures originating outside the body, be they extreme temperatures, chemicals and biological agents, vector-borne diseases, or any other potential factors.
