The deeper you look, the more you find self interest behind most things in society.
Agricultural hemp would be awesome. Incredible biomass, thrives on poor soil, myriad of uses, no food competition.
Instead, we try to do it with corn, a nitrogen hog.
Sigh.
Another advantage of hemp is it eliminates the need for ethanol. Ethanol is made from corn, creating a competition for corn between farmers and ethanol producers... this drives up corn prices which in turn drives up the cost of beef and pork. Eliminate that competition and beef and pork prices come down (or become profit for someone else, which brings the self interest thing in again)
Well, that makes too much sense -- have to discard that idea immediately!
the problem with self interest is?
