Indisputably wood smoke is toxic and poisonous. That means if you use a woodburner and you have neighbours you are poisoning your neighbours. How can poisoning your neighbours be a moral act?
That’s why not only should woodburners be banned, but their use should be criminalised.
Yes it is really as simple as that. It’s not some shade of grey. Wilfully polluting, poisoning and causing harm is an immoral act. There should be legal sanction against such activity.
