Meat is great. Driving anywhere I want as often as I like is great. Cooling my house in the summer is great. Buying products made of plastic is great.

I don't want to stop doing any of these things, they make my life great. I could radically change my entire lifestyle to something much more limited and uncomfortable, only for the gains to be eaten up because my neighbor refuses to use contraception, and refuses to teach his 5 kids to use contraception.

The onus of climate change falls on people whose carbon footprint is exponential. Not me, mine is finite. I'm not going to move mountains in my life to make a difference that's fractional compared to other people's careless reproduction.
