The pattern through history has not been to give up resource use, but to continue using as much as is feasible, while developing new technologies that allow the shift to new, more common, resources and using less harmful methods to collect them. To live off less is not a "change" as previous ones have been, it would require a massive shift in what human beings are. this isn't going to happen, and it would hurt society more than it helps to do so. It is through luxury, through frivolous crap like facebook, that new industries are formed, that progress is made. The computer was a hobbyists plaything. The internet driven by people who found it fun. What do we restrict? How do we lower resource usage? You can't do it without harming progress more than you buy time, not in a way that substantially lengthens the time humanity has left on earth.
