Islamabad    -   The COVID-19 pandemic underscores more than any time in recent history how important it is to protect public health. Yet, as countries race to develop a coronavirus vaccine, another everyday killer continues to threaten billions of people worldwide: air pollution. New data from the Air Quality Life Index, which converts particulate air pollution into its impact on life expectancy, reveals that particulate pollution was the greatest risk to human health before COVID-19. And without strong and sustained public policy, it will be after COVID-19. Conducted by the Energy Policy Institute at the University of Chicago (EPIC), the analysis finds that particulate pollution cuts global life expectancy by nearly two years, relative to what it would be if air quality met the World Health Organization guideline. This has consistently been the case over the last two decades, with the average global decline in life expectancy from pollution remaining at two years as improvements in some countries like China were balanced out by worsening conditions in other countries.
