Air pollution has shortened human life expectancy by one year on average across the globe. In the publication Environmental Science & Technology Letters, scientists report life expectancy in more polluted regions of Asia and Africa have reduced on average by up to two years due to fine particulate matter. These particles are smaller than 2.5 micrometers and have different impacts on population from country to country. But even in high-income countries like the U.S., the pollution particles contribute to earlier death. The report also calculated the potential benefit of limiting fine particles levels to the World Health Organization’s (@who) recommendation of 10 micrograms per cubic meter of air. If this standard was met, India, which is one of the most polluted countries in the world, could give a 60 year old person a 20% better chance of living to 85.
