A lot of that air pollution is emitted producing products for the US & European markets.
A few years ago it was "this isn't happening" now it's "these other people do it far worse than we do."
I also don't buy that if everyone was producing at smaller scales at home, this problem would be at all better. This is a consumption problem, not a "globalization" problem.
I agree with you that this is a consumption problem, but globalization is what has driven consumption for the past 30 years.
That's a hell of a caveat.
The “right” in the US is now staunchly in favor of trade wars instead of free trade. Not what you’d expect given their history.
