The ethics of corn ethanol

We were told by the TV reporter last night that Easter eggs will cost $.34 more a dozen this year. Corn ethanol is the reason, but reporters probably don't want to look on the down side of Al Gore's movie theories. Such as, China has now caught up to us in emissions (a decade ago we were told it would be 2025), so we could burn water in our automobiles and it wouldn't make a bit of difference in the global temperature, assuming that emissions are causing warming, which many scientists say is a bunch of cow poop. Being Americans, we not only think we are God, but that only what we do to the atmosphere matters, and the only hurricanes that hit land, are the ones we see here.

But let's look at the ethics of ethanol.

" . . . about 29% more energy is used to produce a gallon of ethanol than the energy in a gallon of ethanol. Fossil energy powers corn production and the fermentation/distillation processes. Increasing subsidized ethanol production will take more feed from livestock production, and is estimated to currently cost consumers an additional $1 billion per year. Ethanol production increases environmental degradation. Corn production causes more total soil erosion than any other crop. Also, corn production uses more insecticides, herbicides, and nitrogen fertilizers than any other crop. All these factors degrade the agricultural and natural environment and contribute to water pollution and air pollution. Increasing the cost of food and diverting human food resources to the costly inefficient production of ethanol fuel raise major ethical questions. These occur at a time when more than half of the world’s population is malnourished. The ethical priority for corn and other food crops should be for food and feed. Subsidized ethanol produced from U.S. corn is not a renewable energy source."

And he doesn't even mention the bioterrorism of a well placed fungus that could wipe out the Americans' dependence on corn for fuel the way the potato blight sent the Irish running for a new country in the 19th century.

and the CO2 emissions of corn ethanol

"Proper mass and energy balances of corn fields and ethanol refineries that account for the photosynthetic energy, part of the environment restoration work, and the coproduct energy have been formulated. These balances show that energetically production of ethanol from corn is 2–4 times less favorable than production of gasoline from petroleum. From thermodynamics it also follows that ecological damage wrought by industrial biofuel production must be severe. With the DDGS coproduct energy credit, 3.9 gallons of ethanol displace on average the energy in 1 gallon of gasoline. Without the DDGS energy credit, this average number is 6.2 gallons of ethanol. Equivalent CO2 emissions from corn ethanol are some 50% higher than those from gasoline, and become 100% higher if methane emissions from cows fed with DDGS are accounted for. From the mass balance of soil it follows that ethanol coproducts should be returned to the fields."
