OK, nice talking and all, but we need solutions applicable in real world, not something looking nice on paper (we ALL know this is best, and I hope most see it's unrealistic to expect mankind to behave like this... we never did and never will).

So I could say OP is more off than you think, and he could say... whatever. The worse the situation will get, the more people will be willing to sacrifice their well-being, invest in groundbreaking expensive new tech etc. We are not there yet, not the nations holding most of cash in their pockets.

Oh, and don't get fooled - you can put any cancerous lung photos on cigarette packages, I don't know a single smoker that would change their habit based on this. They ALL know it's bad and can kill you and go on nevertheless, don't treat people like stupid children.
