Dump crop residue in the ocean?

An article in today's New York Times - click here - suggests that in order to sequester CO2 we should be bailing up corn stalks, wheat straw and other crop residues, then hauling the bails to the ocean and giving them the heave-ho.

That would keep the plant matter from decomposing and "in effect, sequester atmospheric CO2 on a time scale of millennia."

Hmmm. If we're going to all the trouble to gather up that residue, wouldn't it make more sense to haul it to a cellulosic ethanol plant and turn it into a usable fuel? That way we could keep more oil in the ground instead of coming out our tailpipes. A two birds with one stone kind of thing.

Just a thought.
