I guess it comes down to costs. If corn based plastics are more expensive than cheap oil based ones, who will put in the time and money to promote them?
Yes, Fertilizer is another issue, but it may be better if we do less with fertilizers, as a lot of that material runs off into the rivers and lakes. That may be an OK trade off if we can still work on producing food crops that need less of the stuff.
That brings up the question of bio-fuels. How much corn that we grow goes to feeding people, feeding animals, and into fuel? I've heard several complaints that we don't use what we have to feed the hungry, and now we're going to divert crops for fuel production. Which is the ethical thing to do?
