Detailed energy outputs and inputs were assessed for the following crops, cultured in the U.S. and developing countries: corn, wheat, rice, soy, potato, cassava, tomato, citrus and apple. In addition, the labor input for each crop was analyzed.

Starvation is the number one cause of death in the world. Approximately 40% of U.S. corn is being converted...
