>Feeding these increased populations will require an agriculture far
surpassing sustainable methods, such as organic, or case in point, slash
and burn sweet potato production with a 25 year rotation, which is truly
sustainable.

Jim, I'm in agreement with you.  I'm not in any way promoting that we give
up high tech, or go to all organic or slash and burn.  My point is that any
system that requires major change is by definition not sustainable.

That said, there are current and will be future agricultural practices that
are both highly productive and sustainable in the long run.  And I don't
have a problem with short-term solutions.  But I wouldn't call them
sustainable.  By my definition, if you don't expect them to work for your
great grandchildrens' generation, then they can't be considered as
sustainable.  I don't mean to put any negative connotation on
nonsustainable.
