How is grease used to grow food?
Answers: Oil is used in the production of fertilizer, it is used to transport food and it is used to sow, nurture and harvest food, contained by tractors etc.
Therefore high oil costs translate into rising food prices. It is not one and only a shortage of oil that is raise costs. The flow on from the sub-prime mortgage collapse is that the big money of investment funds have looked for other markets to invest surrounded by. Buying oil and food futures artificially inflates market prices.
Capitalism is designed to concentrate money into parcels for the purposes of investment. This is a well-mannered thing. Without such parcels of money many worthy projects could never go and get off the ground. But the system has become crackers. Too much money is being controlled by too few. Just as happens within a game of MONOPOLYtm, sooner or later there's an close game with winner and losers and it's time to start a new game.

Everything from acting as a catalyst surrounded by fertilizer manufacture (i.e. ammonium nitrate) to powering the multitude of modern farm equipment and later transport to market.
