Air pollution is one of the biggest—and most overlooked—health threats of our time. From asthma and respiratory infections to chronic lung disease, polluted air affects millions of people every day. In communities already facing poverty, conflict, or weak healthcare systems, the health consequences are even more severe. MSF teams see firsthand how environmental damage turns into medical emergencies, especially for children, older people, and those with existing conditions. Clean air is not a luxury—it is essential for health.
