Climate change is the greatest threat to public health worldwide and doctors must step up to help mitigate it, according to a leading advocate speaking at the annual Canadian Medical Association (CMA) meeting in Vancouver on Monday.
Dr. James Orbinski, a former top official with the medical charity Doctors Without Borders/Médecins Sans Frontières (MSF), who is now an an associate professor of Medicine at the University of Toronto, urged physicians to "step up and step out" in the fight against climate change as part of their duties to create "health-in-all" policies.
