We are currently fighting a war over petroleum. Besides the war in Iraq, the price of gasoline has created havoc in our economy. An argument could be made that the severe weather that we’ve been experiencing the last several years, which has interrupted the flow of fuel to the United States, is due to our use of oil. Oil prices seem to be on an ever-upward trajectory affecting the price of everything it touches. Food prices have just started to go up and I don’t think that trend will change anytime soon. Most of the chemicals used in agriculture are made from petroleum. The fertilizers and pest controls are made from petroleum. The equipment used to plant, maintain and harvest the crops run on petroleum. The trucks and trains (and planes) that transport our food around the world to our tables run on petroleum. Every step of the process is dependent on this weak link in the world economy. We’ve seen it happen before and we’ll see it again in the future. And, the food chain is only one example.
