No doubt recycling methods will become better technologically, but simultaneously
the means of producing new materials will become more efficient. I've never
understood why people are concerned about recycling or why getting people into the
habit of recycling should be considered "good."

It is easy to convince people to, and they are already in the habit of, doing what
is most cost effective and cheapest. The problem resolves itself. If it is ever
more cost-effective to recycle, we will, naturally. As long as it isn't, we won't
and shouldn't.

Hmmm... arguments about externalities are a little more complex, but I'll save that
for if you bring it up. ;-)
