Worldwide, high crude oil prices, increasing extreme weather events, population growth and economic development of poorer countries, crop-based biofuels, political conflict and unrest in the Middle East, and slowing crop yield growth are all factors contributing to rising food prices.

U.S. Wastes More Food Energy than Gained from Gulf Oil & Gas

Wasted food energy in the U.S. totals some 2150 trillion kilojoules per year–more than the U.S. could produce in ethanol (grain) biofuels. Further, an article in the New Scientist asserts that this amount is greater than the energy produced annually from all the oil and gas extracted from the Gulf of Mexico.

Question: How to Curb CO2 Emissions and Feed the World?

In a recent paper published on the Proceedings of the National Academy of Sciences website (Greenhouse gas mitigation by agricultural intensification, by Jennifer A. Burney, Steven J. Davis, and
David B. Lobell), the authors estimated the GHG emissions from U.S. agriculture for the period from 1961 through 2005–a period of great agricultural intensification–and show a massive decrease in GHG emissions as a result of this intensification.
