Less than 1% of earth has safe levels of air pollution, study finds

Air quality is particularly worrisome in regions such as southern Asia and eastern Asia, where more than 90% of days had PM2.5 concentrations above the 15 microgram threshold

It’s no secret that air pollution is a serious problem facing the world today. Just how serious? A new study on global daily levels of air pollution shows that hardly anywhere on Earth is safe from unhealthy air.
