I doubt all the cooking and heating wood stoves combined equal to the "pollution" put out by a decent sized forest fire.
I agree with Nate. With the amount of forest fires we have every year and the use of open fires in 3rd world countries, the least of their worries should be EPA approved stoves in the US
Don't worry,we will spend millions studying cooking on campfires,and probably send people on vacations(overseas) to study this.
In the end it ain't about cleaning up the air, it's about them not collecting your hard earned money and your being self sufficient. ....big brother don't like us fending for ourselves......
