Can't this corn-for-ethanol be used directly as livestock feed or even human food if needed?
Also, I have no idea where i heard it, but i remember from somewhere, that pretty much all of the pet food has to be edible by humans too, "just in case" shit hits the fan..
Most field corn is not directly palatable for humans. Livestock feed, yes. There is lots of stuff we could eat to get nutrition from when shit hits fan. Most of us don't haven't tried though, lol
