A staggering 99% of the population is breathing air that exceeds safe quality limits set by the World Health Organization (WHO).

This episode of "Let's talk cancer" delves into this public health crisis with Dr Maria Neira, Director of Public Health, Environmental and Social Determinants of Health at WHO.
