Gas affects everything. Where I live, I think its up to $1.50 a litre. I don't pay for gas, I take the bus. But a bus fare is up to $2.50 a ride, or $70 for a monthly pass, due to the fuel cost.
Now, what I will say now is going to sound crazy and you wouldn't think it related. But the cost of flour has gone up sharply, perhaps 300% in a short while. The reason behind it is the discovery of biofuels. Now, farmers have found that with biodiesel, they can make a fortune off of growing corn and soy for the oil. Which then leaves them abandoning wheat. Unfortunately, flour is used in... everything! Pasta, bread, cakes, cookies, mixes, all kinds of things!~ This means that food that uses flour gets even more expensive because the supply is getting thinner.
But with the cost of fuel to transport things getting more expensive, food rises accordingly in price to cover transport costs as well.
With fuel prices high, it is quite possible that with this panning out to the market for food, a lot of people will be starving soon.
