People in the global south, who have a tiny fraction of the carbon footprint of those in the north, are the first to be devastated by the climate and ecological crises, which they're least responsible for.
If you're considering shopping for your next $40k monstrosity of a vehicle, try to take a broader perspective than your own short-term desires.
Instead of harassing the ancestor for not perfectly optimizing their use of resources (which has zero impact on the climate one way or the other) or harassing me for suggesting that an 80/20 solution to a problem is better than no solution, perhaps you should try to take a broader perspective and realize that most people are selfish: they aren't going to massively sacrifice their quality of life in order to help people in the global south that they don't have relationships with. Aligning incentives to help them do the right thing (e.g. by creating a vehicle with a form factor they can readily accept while still being an EV) is the smart way to go at the problem. Brow beating people for not being totally altruistic and demanding they make massive cultural changes is the dumb, ineffective way to tackle the problem, although it does allow the participants to feel morally superior as they fail to convert anyone else to their cause.
