In response to the posting by John McCarthy:

The terrestrial environment is an entropic sink from which it is more
energy-costly to extract degraded materials than you think. Yes if
our consumption were low enough -- as low as it could be in compact
cities. But at the cost of the destruction of the natural ecosystem,
and I think that is too high a price, especially since there is such
a small distance from the kind of compact cities that continue to draw
some materials from the environment and the kind that are truly
self-sufficient over geologic time. At some point it is easier and
cheaper to simply recycle 100 percent of the materials you use than
to dispose of .001 percent of them and then go out and try to recover
that .001 percent.
