A natural gas flame is much better for air quality than any other common combustion-based heat source (like, sure, hydrogen would be a bit better, but...).
Not arguing the air quality, just wanted to point out how stupid it is to argue for something just because we did it for thousands of years.
Cool - let me just burn oak or pine everyday in my kitchen that sounds like a GREAT idea
Right. And why did we end that time-honored tradition? Soot pollution, and deforestation. In other words, the environmental impact of those fuels.
