A new Promotional published in The Lancet…in need of revision!

One Health is a concept that recognizes the links between human, animal, and environmental health. These factors must be incorporated and integrated before planetary health can be achieved. The One Health concept promotes multidisciplinary collaborations between physicians, veterinarians, environmental specialists, and other health-related professions. Support for One Health has increased substantially and must be embraced and implemented globally.(2) Regrettably, Richard Horton and colleagues’ manifesto for planetary health excludes One Health;(1) as such, it is incomplete and ineffectual. It does not adequately address the overwhelming environmental threats to the sustainability of human civilisation. Our planet is rapidly sickening because of anthropogenic causes, but planetary health for humanity is impossible without including animal, environmental, and ecosystem health.(3) About 75% of emerging infectious diseases are zoonotic; many emerge because of environmental destruction.(4) We must recognise that planetary health equals human, animal, environmental, and ecosystem health.  Achieving planetary health requires implemention of the One Health concept globally. We declare that we have no competing interests. *Laura H Kahn, Bruce Kaplan, Thomas Monath, Jack Woodall, Lisa Conti Princeton University, Woodrow Wilson School of Public and International Affairs, Science and Global Security, Princeton, NJ 08542, USA (LHK); Retired, Sarasota, FL, USA (BK); PaxVax, Menlo Park, CA, USA (TM); Retired, Rio de Janeiro, Brazil (JW); and One Health Initiative, Tallahassee, FL, USA (LC)   1 Horton R, Beaglehole R, Bonita R, Raeburn J, McKee M, Wall S.
