It is the demands of ethanol that are the force behind GMO grains. Also, the byproduct of extracting the alcohol from GMO altered corn is fed to livestock, introducing GMO into the food chain for human consumption.
(T)he ethanol industry disputed AP's findings that as farmers rushed to find new places to plant corn, they wiped out millions of acres of conservation land and destroyed habitat. The industry said the primary driver for such losses was Congress lowering the number acres allowed in conservation, not ethanol.
But it was the ethanol industry that lobbied Congress to lower the number of acres allowed in conservation. A simple geometry theorem says "things equal to the same thing are equal to each other" so this statement has no standing.
Also think of the consequences of the price of corn falling. Lowering the cost of livestock food would result in an increase in livestock which in turn would lower the price of livestock, bringing back into balance the cost-price structure of supply and demand. Some of those acres would be planted with other crops, driving down the price of those costs as well and that would ripple through the economy as well while some of the now cheaper corn would be exported overseas.
Lastly, there would be no ethanol industry without the tax subsidies that allows the 10% ethanol blend to be sold for 10 cents a gallon less than regular gasoline (at least in the mid-west). By definition that is socialism. Myself, I would like to see many of these tax subsidies reassigned to clean, alternate energy such as solar and wind.
