The other part is pollution.
“Part of it.
The other part is pollution.”
I don’t know how old you are but if you don’t remember the 40’s and 50’s you dont know what pollution is.The air has never been cleaner and its about as pure as it is ever going to get. Maybe some big city air sucks somewhat during inversions, etc but they suck in every other way as well. I worked in downtown Chicago for 17 years up to 19 96 and don’t remember any real bad pollution days except some scattered ozone warnings, Again, I think we are about as good as we’ll be.
