The modern foods won't be cheap for long.  As petroleum gets more and more
expensive, it will be the conventaionally grown foods, with pesticides,
herbicides, and many many tractor passes over the wheat corn and soybeans,
that will become too expensive.  Organic food will become relatively
cheaper. Price supports won't be able to overcome the differential.

Another major change is that we will perforce eat food produced near to
where we live; it will be too expensive for foods to travel the current
average of 1500 miles to reach our supermarket.

We Paleo eaters, like the locavores, are just ahead of this curve.  Now is
the time to start growing your own, eating local foods, eating foods in
season, avoiding the highly industrialized foods.

Thinking about what our children and grandchildren will eat, 20-50 years
from now---chances are they will eat more like 1900 than 2000.  I just
worry about the transition; will every tree be cut down for fuel? will
every edible animal species be wiped out?  It behooves us to prepare for
this transition.  Unlike the demand for grass-fed beef increasing the
relative supply, demand for petroleum CANNOT increase the supply in the
earth.  What we've got, we've got.  And when we're out, we're out.
