Ever wonder what Beijing air pollution looks like when it's not extreme enough to make the news? This. This is a "nice" day. Notice the hills in the background in 2nd picture. What you see is PM10, or particulate matter 10 micrometers wide. It's the PM2.5 that can enter the bloodstream and cause the most damage though. The scale used here (@129) is out of 500. The "healthy limit" varies by country, but generally accepted to be 30-50. China's is 70. To China's credit though, the CCCP has enacted some drastic reforms to reduce air pollution and invest heavily in clean energy. Some headlines from 2018: "For every $1 the US put into renewable energy last year, China put in $3" "Solar And China Dominate Clean Energy Investment In First Quarter"
There's a long way to go, still a lot to clean up, and much education to do, but there's #progress nonetheless.
