Also, I’d like to point out that in places like LA you’re going to see bad air quality. Think of a population being that dense and everyone driving around cars 24-7. We have many conveniences at dense populations, that most countries don’t. This contributes a lot more to air quality. Because it’s harder to point a finger at joe who’s commuting to his job than it is to point a finger at industry and agricultural entities. However, progress is being made through things like the clean air act where they can point fingers. Also, most states\cities\counties with dense population have developed air emission regulation and requirements for vehicles.
