What the alternative for heating? If it is AC, consider that much of the electrical grid is powered by air pollution anyway (especially coal), so the issue is at best deferred.

In urban areas, I believe the biggest cause of air pollution is vehicles, not woodsmoke.

My house has a fireplace but I still haven’t ever used it after living here for almost 5 years. I prefer the firepit outside if I’m gunna have a fire.

However, aren’t there still people that use this as their only heat source?
