Here, yes. In China, not so much. Of course, their classifications for air pollution are markedly different from those used in Europe and North America; "Excellent" in China is roughly equal to our "good" to "moderate", while their "good", "light" and "moderate" classifications all fall into our hazardous zones. Apparently, a "pretty good day" in Beijing means that you can see across the street.
Obviously, we need ever greater restrictions here in the USA, otherwise "we" may not be able to Save The Planet™. The air pollution in China's so heavy that rumor has it that our weather's being affected. And that's hardly the end of it: fully one-fifth of farmland in China is now heavily polluted, as are their waters.
Interestingly, America's one of the cleanest areas on the planet by all measures of air, soils, and water quality, yet our overlords - both elected and unelected - continue to impose punitive costs and restrictions on us. At some point we need to make it clear to them that enough is enough; when the rest of the world catches up to us, then we'll talk.
