In all of the arguments to date that I've seen against ethanol, every one throws out the 1/3 high protein animal feed.
Instead, for purposes of advancing their sides argument, they assume that 1/3 to simply be landfill material, and of no value to anyone.
In actual large scale animal experiments done by universities, that 1/3 is sometimes as high as 1/2.
Lots of folks think we’re wasting food on fuel. Vegans think we’re wasting food for people on animals.
The use of lots of products is mandated by the gov’t; sanitary sewers, hardhats, catalytic converters, etc. Somewhere I missed the outrage at people who produce those things...
