- Air pollution causes millions of premature deaths annually, primarily from chronic exposure to pollutants.
- Key pollutants include sulfur dioxide (SO2), nitrogen oxides (NOx), black carbon (BC), methane (CH4), ammonia (NH3), and non-methane volatile organic compounds (NMVOCs).
- Pollutants harm health through direct toxicity, formation of particulate matter (PM), and ozone (O3), leading to respiratory and cardiovascular diseases.
- Major sources of air pollution include energy production (coal, biomass), transport (vehicle exhaust), agriculture (livestock, fertilizers), and industrial processes.
- Solutions to reduce air pollution include transitioning to clean energy, improving vehicle emissions standards, and reducing meat consumption.
- Many countries have successfully reduced air pollution through regulations and technological advancements, leading to improved public health.
