How Toxic Is the Air You Breathe?
May 28, 2026
Summary
This episode explores the tragic story of Ella Kissi-Debrah, a nine-year-old girl whose severe asthma was triggered by illegal levels of air pollution in London. With help from Professor Stephen Holgate, her mother Rosamund proved that nitrogen dioxide from traffic contributed to Ella’s death, leading to the first-ever death certificate listing air pollution as a cause. The narrative contrasts this victory for clean air advocacy with recent US deregulation efforts, highlighting the ongoing global struggle against invisible environmental hazards.
