There is another aspect of uncertainty that surfaces as a potential threat to con- sistent supply and that is the "food versus industrial" use of crops in the future. One side of the debate is the shortage of supply theory. "How can agriculture feed a burgeoning population and supply raw materials for consumer goods?" "Won't crops used for feed-stocks be redirected to the food supply in times of world famine or drought?" Good questions. However, the implied assumption is that we have a choice. The demand side is growing for both food and raw materials and even if we do not develop renewable industrial resources then food.
