The biofuel isn't the primary source of high food prices - on the vice-versa! It can be demonstrated easily by the look into history of the latest oil price crisis in the mids of 70's:
As we can see clearly, the history just repeats by now: the food prices are copying the oil prices - and in 70's no biofuel concerns was ever known. The raise of oil price was started as the result of decreasing price of dollar in consequence of Iraq war. If the money value goes down, the investors are looking for more permanent investments and the will changing their money into material commodities. The reality market and mutual funds were collapsed first and now money are transferred into more volatile markets: the oil and food in particular. It means, the primary source of oil and food price raise is the Iraq war in analogy with Vietnam's war, which was ended in the mid of 70's.
It means, if the USA government will continue in war with Iran, it will result into collapse of dollar and the global economy.
