But a lot of countries might be saying "well we don't need to clean up
so much because we simply use /produce less."

I wasn't aware of any world central government
coming into power. :-)

And I am not convinced there is a problem,
about the only pollution that may spread outside
North America is from forest fires, and everything
possible is being done to prevent them and put
them out.

Oh thank you, thank you!
