Fighting climate change is crucial primary care medicine. Climate health is crucial for public health. Science continues to demonstrate that we must join together with the rest of the world to slow climate change. This will require a concerted effort to reduce reliance of fossil fuels, limit industrial and agricultural pollutants, and strive for equal access to clean water. I feel compelled to speak out as a provider of primary care for all people impacted – which is all of us. Invest in health, not in fossil fuels.
