I would be surprised if dredging up seaweed from the ocean and barging it up the Mississippi and putting it on a train to Omaha where it will be trucked to rural Nebraska could possibly be cost effective against the grass in the pasture the cows are already in. That seems to be job creation in the “I shot myself in the foot, so my doctor has job security” sense. Or are we building oil-rig style floating pastures to cut transportation costs?
