But you're missing one important point. Our standard of living is due to previous free enterprise and a so-called free-market economic system. Also, we reportedly live in a "free" society. So you have to win people over or hit them with a stick, which usually goes over real well- not.I certainly don't have a solution. But when asked why we should have to curb our emissions when other developing countries are not, it's because we believe it's the right thing to do (granted, not everyone shares that sentiment) and we can. Our standard of living affords us the luxury to try and make a difference.
But the biggest issue I'm seeing is that when the "selling points" of doing this or that to make a difference as you say doen't convince enough people to want to make that difference, then instead of going back and making a better and more convincing argument or revamping the messaging, it's typically just forced upon the masses when discussions don't work. Don't like Kalifornia's laws? Then move out of the state. Start voting for people that share your views, mostly anway. Whatever's important to you.
Just because it can damage the earth, doesn't mean you must act to save it. Especially if the majority of the rest of the world isn't. So you may extend life on average another 15 minutes with all that effort and money. Ok.
It's similar to someone dying on the sidewalk. If you don't render 1st aid, that's a choice. And you won't go to jail if you don't render 1st aid. Person could live or die, but it's a choice you have to live with, whichever one you choose.
