You can see smog, but it still requires government intervention to effect change.
I was recently in a small Asian village where the pollution gets very bad for a couple months when farmers burn the sugar cane and rice fields. I mentioned it to some locals, and they thought the thick haze was just harmless "mist" from the winter weather patterns.
In the Netherlands, millions of people burn wood in stoves or fireplaces, just for coziness, or use it for heating where alternatives are readily available. The evidence for its massive detrimental health effects is overwhelmingly clear. When you dare to even present this evidence, you will get flamed and ridiculed as if you are an evil luddite out to take away their small pleasures in life.
We are slowly getting rational about the effects of smoking, but choking out your neighbors (and children) by burning wood is still something people feel is their human right.
