GreaseMonkey suggests harnessing animal power as a potential sustainable practice as farming (i.e. energy) costs start taking a hit.
However, Philaelaethes reminds us that insane right-wing fundies prefer beasts of burden for other purposes. Very not sustainable. The animals likely won't want to volunteer for the work; we will probably have to draft horses.
I heard that audio played by Mike Malloy on Air America Radio. Paraphrasing Malloy, Colmes comes across just as detached from reality.
