When you sum everything up, air pollution is responsible for eight million premature deaths every year–equivalent to 15 people dying every minute of every day.

In “A Noxious Problem,” we’ll look at why the world’s biggest public health crisis is only getting worse, despite attempts to fix it. Regulatory corruption, global inequality, and naive techno-optimism all play an integral role.
