At Doctors Without Borders/Médecins Sans Frontières (MSF), we see how environmental changes impact human health. We know that the most vulnerable people will be the most affected—and we’re already seeing them in our waiting rooms. In this video, MSF medical director Dr. Monica Rull and planetary health coordinator Brian Willett talk about the health consequences of climate change and environmental degradation. "Our health depends upon the wellbeing of the planet, and the wellbeing of the planet depends on how we act," explains Willett. "It is all linked."

MSF sees the climate crisis as a public health crisis. We are reaching out to help people who are most at risk, while also working to reduce the environmental impacts of our own aid efforts.
