Except that it's not true. When you release CO2 into the air,
it doesn't matter where it CAME from. it only matters where
it would have gone if you hadn't burned it.
Yes, it does matter where it came from. In the case of biofuels, the
carbon all came out of the atmosphere, so you are not adding any more.
In the case of fossil fuels, all the carbon came out of the ground, and
you are dumping it into the atmosphere, causing a carbon buildup.
It doesn't matter whether you burn corn or not, all the carbon will end
up back in the atmosphere unless you protect it from decay. If you want
to sequester carbon, you have to put it back into the ground. That's
why those landfills full of disposable diapers have their up side.
