Thanks for the data! Is it unreasonable to think that as energy efficiency of things (cars, heating systems, airplanes) improve and we move towards renewable energy that the inefficiency of rural life could become offsetting and the value of nature on the human psyche is allowed to return to our culture?

I realize that's more of a value judgement and not objective. But there are definitely costs associated with living in dense urban places. Regardless of efficiencies we are definitely still living in a post-industrial-revolution world, and people did not voluntarily cram themselves into giant cities then, so some sort of reversion when it's possible makes sense. Vast populations of urban people in China would rather not have to move into the city.
