> if you model a simple assumption that resources get more expensive to extract over time Why would you make this assumption? Resources get cheaper to extract

  Technology improves but resources get more scarce. Oil is getting more expensive to extract, for example. The same is true of many mineral resources, as we're forced to move to lower-grade ores. But your point is a good one. I basically see us as being in a race between technological improvement and environmental catastrophe. I'm not at all sure which side will win. It'd be nice if policy makers would help weight the race in our favor.
