Oh yeah, I remember hearing about that! I mostly stopped paying attention to it when my ag education ended in 2002, so my info is old! Thanks for the more up to date info.
Either way, the depletion of hops has little to nothing to do with farmers switching to corn for ethanol production like someone suggested.
As a biofuel, ethanol SUCKS, and it's giving biodiesel a bad rap. Now congress (ruled by oil barons) is HOPING to restrict ALL biofuels because of the food "crisis", and they want to blanket all biofuels because of the impact ethanol crops have had on the food economy. The real story is they want to persuade everyone through fear tactics that all biofuels are bad so that we'll keep driving on gasoline and they'll keep getting rich off of us. There is a HUGE difference between crops used for ethanol and crops used for biodiesel - biodiesel uses byproducts of the food industry and doesn't take away from food production whereas ethanol uses a whole crop and directly competes with the food supply. While they are both technically biofuels, one is far more sustainable (and efficient) than the other.
Just pay attention to the hype that is rampant in the news right now and you will notice that there is (intentionally) rarely a distinction made between biodiesel and ethanol...it's a total conspiracy to convince people that BOTH are bad and BOTH are causing the rise in food prices when really the problem is only being caused by Ethanol. Friggin' oil bastards! Will they ever be rich enough?
