The rising food prices are not completely the result of increased production of bio fuels, but bio fuels certainly play some role, just not that major. Bio fuels are mainly made from corn and soy plants and thus would not explain the sharp rise in prices for other commodities such as bread, rice, and dairy. i believe that yet again the problem mainly comes from the rise in oil prices as these affect the money that is put into harvesting and selling the crops. Natural disasters within the last few years have hit important crop areas in the united states as well as other parts of the world a few years earlier.

What I'm getting at is that there are many causes for the rising cost of food some of which, oil, we have the ability to solve and we should do what is necessary to do so. Rising food costs will greatly increase tensions in the world, possible making some areas even more volatile than they are already. Poverty will probably increase as well as sickness and probably death. we are continuing to deplete the earth of its resources and eventually if we don't solve are problems with oil, war, poverty and others, we will be forced with the problem of overpopulation and that will be nasty to solve.
