There’s more to pollution than CO2. You’re polluting the neighborhood with smoke, which is bad for lungs. Maybe okay in a rural area if neighbors are far away.
I guess we can just keep ordering pre-stuffed PCBs from JLCPCB. This way, the pollution involved in the various processes still exists, but it's hidden from view behind a box of minty-new circuit boards delivered to the doorstep.
Or, you know: If the neighbors take up a serious hobby-scale effort of wood-fired pottery project with local clay that they mined themselves, then... Perhaps we could be supportive of their effort, eh? Isn't that part of what being neighborly involves?
