What food crisis?
Less corn means potentially suspending ethanol requirements in gasoline. Who thought it was a good idea to burn food in cars? (Answer: Nixon)
Ethanol production just uses the starch out of grain (corn typically) to make ethanol.
The remaining byproduct, Distillers Grain (DTS) contain fat, protein, fibre, phosphorus and sulfur and are roughly are three times as concentrated in DTS than in the original grain.
Cattle feeders mix that with ground cornstalks or other roughage. It makes great cattle feed.
More ethanol does not mean less food on your table.
By the way, I don't raise cattle or have anything to do with the ethanol industry. I am a Soldier and I've been to the middle east twice. If it means less oil from overseas, I'm all for it.
No more wars for oil.
