That's the thing, Biodiesel doesn't compete with food or feed that much, nuless they make it strictly from soybean oil. It can be made from many sources. Restaurants used to have to pay to get rid of their used cooking oil, now they are whining because people are stealing it out of their tanks, a waste product that just a few years ago they had as an expense that now they are crying because some people are clearing them out on it. Thinking like that is part of the problem. Animal fats, which used to be a waste product are also becoming a source. Algae is yet another source that is being researched for use.
