UN says air pollution kills 8 million people annually

The United Nations Environment Programme reports that air pollution is responsible for roughly 8 million premature deaths each year, with 99 % of the global population exposed to particulate matter (PM2.5) levels above the World Health Organization’s safe limit of 5 µg/m³. The report links fine‑particle exposure to progressive damage to lungs, heart and the nervous system and highlights fossil‑fuel combustion, transport, industry, agriculture and residential biomass burning as major sources. It also notes the disproportionate impact on low‑income communities and calls for coordinated political action worldwide.

In Chile, health specialists warn that recent episodes of poor air quality are already aggravating respiratory and cardiovascular conditions, especially among children, older adults and people with chronic illnesses. Dr. Nancy Fontana of Cordillera Interclínica said, “many times these alerts are normalized… they represent a warning about an environment that can silently make us sick.” Authorities recommend limiting strenuous outdoor activity on critical days, improving ventilation and following official guidance to protect public health.
