I agree that it's the demand that has to change. I've come to the view though that the easiest way to do this is to have the consumer pay a higher price, the "REAL price" as myrkul said, the one determined by a market that uses unprintable money. A free market economy will make efficient use of the resources. It will also look into the future and foresee resources being used up and take action (for profit, of course).
and that's exactly why i don't think it will work.The market can be efficient at connecting a seller to a buyer but it doesn't care about humans.
The humans participating need to care about that. That is the only way the market will ever care.
And a rising price makes people care. Look at the 60s vs today (in the US). In the 60s we had huge muscle cars, with gigantic engines, roaring out pure, unadulterated power, and eating up prodigious amounts of fuel to do so. Today, we're starting to see smaller, European-influenced cars, even hybrids and full electrics. Why? Price of gas went up. It's not all gone, but we've already decided it would be a good idea to reduce our usage.
