Position Statement

I am writing my position statement on ethanol. It is very hard to choose a side to be on because there are good things and bad things about the fact of having ethanol. This is kind of a difficult assignment because you just dont know how the world would actually turn out if we were to go all ethanol. Would it be a positive impact or a negative one? I guess right now i'm more against it just becuase I know how the world was when we didnt deal with ethanol in our gas but its really hard to say.
