London's air is chronically polluted. The air in Ealing regularly exceeds World Health Organisation limits for pollution, and is linked to increasing cases of Asthma, Lung and Heart disease, and thousands of deaths each year. At this event, we ask what can be done, and hear from campaigners working to clean our air.
