Yes, no one wants to live in smog... even 100 PM2.5 is bad. It's just normal in northern China, especially in the winter.
Bay area air quality has been bad recently too, but complaining about it would show less empathy than our neighbors deserve.
- seanmcdirmid 9y agoDifferent scales. When the Bay Area hits 100 PM2.5, that is considered really really bad, heck, just being above 30 is considered bad. 100 in Beijing during winter is a good day, you don't have to go outside with your mask on.
