If the could grow corn or soybeans - which are the main feedstocks for biodiesel - it would be better for everyone if they just used it for food production, as opposed to refining it and shipping it over here.

Where would they get all that water? Corn is a VERY thirsty crop, wheras opium poppies actually produce more alkoloids when given less water.

I don't think they could - hence, one of the many reasons that they don't grow it.

I'm saying that if they had the capability to grow corn, as fizx suggests, then it would be better to use that corn for food, as opposed to biodiesel.

How about FOOD!

There is no food shortage. There is a food distribution problem.

Afghanistan is having massive food shortages and food prices are through the roof. Hunger is a VERY serious problem there.

Growing corn for biodiesel would make very little sense.
