Subsidies
Corn and Ethanol 4 billion dollars for corn alone
Nearly twice the amount for either soybeans or wheat
Profitability Farmers are operating on a loss without subsidies
$45 per acre

Economics of Food
Land Availability 309 million acres of total cropland
88 million acres of land dedicated to corn
Food Supply Farmers growing corn instead of staple foods
Food prices increased worldwide

Livestock
Nutrition Fat content of meat increased
Vitamin and mineral content decreased
Infection Resistant E. coli more prevalent in corn-fed livestock

GM Corn
Production Increase from 119 bu/ac to 152 bu/ac
Prevalence 85% of total corn planted is GM
Vertical Integration GM corn requires pesticide/herbicide from same manufacturer

Conclusions
The process of producing corn-based ethanol has negative consequences
Heavily subsidized
Disrupting the food supply
Energetically unfavorable
Corrupting the integrity of food
Aiding the formation of vertical monopolies

Biofuels
Good but not good enough 1st generation technologies were a good start
2nd generation technologies are promising
3rd generation technologies are ideal
Solar, wind, and ocean energies are better
Biofuels swap OBEC for OPEC
Conclusion: Biofuels are a great intermediary step to other sources of alternative energy
