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.

Good lord. So glad my country has strict animal welfare standards for livestock. Uncomfortable that we still import and slaughter pigs from countries without those standards. (And yes, we import-and-slaughter because we don’t import pork itself. We do however, allow the import/export of live animals, so international trade buys our sheep for ‘breeding’, and sell us their pigs for ‘NZ-made pork’. I suppose it at least enforces abattoir health standards…?)
