If we took the soy beans our farmers grow and press the soy oil out of it, then take the non-food corn and make ethenol, mix the two to make green diesel, we could still sell the soy paste left over to sell as food overseas AND reduce our dependence on foreign oil as well as helping our environment.
I can't say I have a problem with that at all. Personally, I think this mode of fuel creation has been too long overlooked.

Probably because it's a net energy loser.

Bullshit. Do a Google search on "Life Cycle Inventory on Biodiesel". It's an NREL study by Sheehan et al, BD is much more effiecient, life cycle wise, than petroleum diesel.

I've posted this before somewhere with links to the data, but the total annual carbon uptake(fixing atmospheric CO2) of all vegetation on the planet is equivelent to about .25% of our annual demand for hydrocarbons.
If biodiesel could sustainably replace petroleum,even by utilizing the entire produce of the planet, Co2 levels in the air wouldn't be rising, because the CO2 emissions would be fixed faster than they were created.
It's all carbon mining, it's just a question of where it's being mined from.
Topsoil is the very worst place to be mining carbon for fuel.
It takes literally millenia to build enough topsoil for agriculture, and we're already running into shortages in agricultural areas because tillage and harvesting depletes it.
