I guess you have to decide what you want.
Land owners and farmers see crop prices where they are, have tillable land out of production that can generate pretty nice income. They have marginal land that if farmed 3 years can qualify for other programs.
People don't like CRP payments for marginal land because it's "welfare" and they don't like that land being used for other production.
You don't want corn to be in the food system, but you don't want to use it as fuel....decide which way you want it.
I guess you need to pick your poison.
As someone who is invested and taking an ass kicking in BioD....it's not going to work.
Corn alcohol isn't as efficient as it could be.
It seems the only answer I can see that keeps grasslands, provides production and produces fuel supplements is biofuels made of cellulose and supported crops like switch grass. They have significant flaws, mostly from the delivery to plant costs of transportation and the volume of cellulose it takes to produce the fuels.
It's absolutely true that too much land is coming into production....but you cannot blame a land owner for using their available ground to generate the money it will right now. Even if they clear the ground, farm it a year or two and sell as tillable....it's worth it financially for the land owner.
Wind and other energy sources are an entirely different subject and I've got input on that too.
