While there are a couple of places where geography can cause a local problem, this does not require everyone to follow the same solution.

“So, how many people who heat with wood are in areas so densely populated that wood smoke is a problem? Really?”
Now if they extended this law to India and China.....
In my own case, my closest neighbor is about 200 yards away, and there is no neighbor where any smoke drifting their direction doesn’t first have to go through a line of trees. While they might smell the smell at times, they never get smoked.
