As people continue to learn more about climate change, they are beginning to realize that it fundamentally is a health issue that will affect everyone in the world.
How climate change is damaging to health depends on where people live. If they live in Beijing or Baton Rouge, climate change looks like air that's so thick and poisoned they can't go outside their homes. If they live in the Midwest of the United States, climate change looks like extreme weather that rages through communities and heat waves that destroy crops and cause heat exhaustion. If they live in New York City, climate change looks like a massive hurricane, which flooded streets, trapped people in their homes without power, and shut down hospitals.
For many communities living downwind from coal-power plants, processes that affect climate change are more local, and look like more childhood asthma, as well as an increase in respiratory diseases among the most vulnerable citizens. People are learning that climate change is already leading to the spread of mosquito- and other vector-borne infectious diseases like Dengue fever and malaria to places that have never seen these diseases before.
The world is learning that it is not possible to support the population when the planet is sick.
In this unfolding crisis, the healthcare sector occupies a unique position in society to admit its contribution to the problem, and to lead the fight against climate change.
First, healthcare is just as addicted to fossil fuels as any other industry, if not more so. Hospitals use twice as much energy per square foot as schools and offices, partly because of the intensity of the business, partly because of a lack of focus to be less wasteful. healthcare is a major polluter.
Given that healthcare is underpinned by an ethical imperative to "first, do no harm," it has a responsibility to reduce all of its pollution and lead our society toward renewable energy, energy efficient products, local and sustainable food systems, safer chemicals and other mitigation efforts that support healthier people in healthier communities.
Healthcare represents 18 percent of the entire economy and is growing. If people can harness the purchasing power of that critical sector and invest in "climate positive" energy sources, they can drive the entire economy toward a more sustainable future. This low carbon development path simultaneously will reduce the rising disease burden and reduce the globe's spiraling healthcare costs.
Second, society needs to become better prepared for climate-change impacts in communities. Hospitals and clinics need to be resilient and self-sufficient. They need to help everyone prepare for the coming storm, as well as administer to the sick and wounded during extreme weather events. They should be the last buildings standing in a hurricane, rather than some of the first to go down. If hospitals have reliable on-site power, they can continue to provide critical care to patients even if the power grid is down for days. The good news is that on-site power can make hospitals more energy efficient, can reduce greenhouse-gas emissions, and save the hospitals money. Toward this end, a global coalition for "Healthier Hospitals" is accelerating the adoption of sustainable and climate-friendly practices, and saving hospitals money in the process.
Third, healthcare professionals are some of the most trusted spokespeople in society. When our society became addicted to tobacco, nurses and doctors were the first to recognize the dangers; they banned cigarettes from hospitals and educated their patients about the dangers of tobacco.
In a global campaign to kick people's addictions to fossil fuels and toxic chemicals, doctors, nurses and other healthcare workers need to be powerful spokespeople for policies that understand the true cost of a fossil-fuel-based economy and support the transition to a renewable-energy and toxics-free future. There are five million healthcare workers in America. They can become climate champions for local climate solutions in their communities, as well as serve as critical spokespeople at the local, state, national and global levels for actions, laws and treaties to rein-in climate change.
In this next period of our collective history, society needs to redefine healthcare. It no longer can focus exclusively on treating chronic disease in individual patients within the walls of a clinic or hospital. healthcare needs to clean up its own system, and live its mission of addressing the environmental and social conditions that are making people sick in the first place.
Healthcare needs to lead the fight against climate change — that is our best remedy to the global health emergency.
