Maize / Corn (1/5)

Major cultivation region: United States

Worldwide production in 2006/07: 702 million tons

Sustainability:
- needs lots of fertilizers and water
- biofuel production increases prices for milk, meat, and corn products
- energy balance: low efficiency, might produce more CO2 than the use of bioethanol would prevent
