Air pollution reducing life expectancy; South Asia most affected

Air pollution is the greatest threat to human health globally, more than smoking, alcohol, or infectious diseases.
South Asia, particularly Bangladesh, India, Pakistan, and Nepal, has the worst air pollution and greatest loss of life expectancy.
China has made major improvements in reducing air pollution levels in recent years.
Fine particulate matter from vehicles, industry, and wildfires is most damaging to health, causing lung disease, heart disease, cancer, and strokes.
Global funding to address air pollution is significantly lower than funding for infectious diseases, despite its large impact on life expectancy.
