This is my theory, take it or leave it. In the U.S.A. I've already seen fuel prices start to impact the transportation(read: heavy truck) industry. The railroads have doubled business(cheaper by rail) in the last year, and at the same time I hear of trucking company's parking hundreds of trucks already. I

Keep in mind, from what I have read/heard the following is _already_ happening!

When diesel hits about $7 a gallon one will start to see in the Trucking industry; massive lay offs, many many independent truckers going out of business, and more than one "large" trucking company(Swift, Werner, etc) also go out of business. This links to the food we buy, and the food we give away to third world countries, and the food we sell, so my best guess is the prices will go up by at least 50%, if not 100%. That 4 dollar gallon of milk will be at least $7-$10(notice a link between fuel price and milk price?)

At $10 a gallon, this will start to impact the "normal" commuter, and the poor will not be able to afford to drive at all(never mind about buying food).

If something were to happen in Iran, I belive overnight fuel will double in price, and in the coming months, shoot up to $300 or more a barrel. Can anybody say $20 a gallon gas? Can any of you guess what this will do to the poor around the world? What its ALREADY doing?

Me personally, I can only do what I can personally do. I commute to work when its not raining. Don't know a whole lot more I can do than that about the price of fuel.
