Wal Mart food prices going the same way as gas in 2015 ????

Could this be why Iran is actively pursuing a nuclear power program ?? Makes no difference... we need the remaining oil for food production

An Unsustainable Situation

With the present rate of population growth, when oil supplies are essentially depleted, the world population will be substantially larger than at present, perhaps even double what it is today. The inevitable conclusion is that in terms of today's living standards and food supply, the situation then will not be sustainable. (Pimentel & Giampietro, 1994a, p. 250). In a later more numeric statement Pimentel and Pimentel (1996) state:

Even tripling the food supply in the next 40 years would just about meet the basic food needs of the 11 billion people who will inhabit the earth at the time. Doing so would require about a 10-fold increase in the total quantity of energy expended in food production. The large energy input per increment increase in food is needed to overcome the incremental decline in crop yields caused by erosion and pest damage (p. 291).

Almost all of the energy Pimentel and Pimentel state would be needed would have to come from oil and natural gas. Thus the relationship which exists between population and oil and gas resources cannot be exaggerated. Oil and gas eventually will be gone. Even if conservation and other measures may reduce the demand, at best, this is not likely to significantly extend the time of oil and gas, and reducing the demand seems unlikely against the increasing food needs of a growing population. Decreasing use will only be caused by decreasing available supplies.
