I do not want to fight climate change unless we have an egalitarian society worth fighting for. I've had older folk ask me why they don't see zoomers recycling as much as they do - this is why.
Also you're wrong. The most positive climate impact you can have is not having a kid, not having a car and not flying, in that order. But none of these will do anything meaningful when Musk emits more on his private jet alone than I could in a lifetime.
Also the meat you don't eat mostly just gets tossed because vegans are such a tiny minority it's not even worth downscaling production in any meaningful sense.
