For example, if we used hemp, we'd get paper and other goods made from the fiber and oil from the seeds. If we used soy we would get oil and the solids left after pressing the oil make good animal feed. Growing plants for BioDiesel would increase farm employment as well. I believe that production prices could be brought down by agribusiness firms if they decided to get serious about it. Bob
