What about the price of gas, there is a much high danger waiting to happen that will drive the price of gas above the availability to the human race. And nobody talks about this danger. First here some math.
1 US gallon = 3.79 liters
1 Imperial gallon = 4.55 liters
1 barrel of oil = 42 US gallons or 0.15899 cubic meters
Here are some daily usage of crude oil 2007;
US daily estimate (2007) 20,680,000 bbl/day X 0.15899 cubic meters = 3,287,913.2 cubic meters daily of space or 116,111,557.19 cubic feet of space
Worldwide daily estimate 2007 85,085,664 bbl/day X 0.15899 cubic meters = 13,527,769
cubic meters of space or 477,728,646.84 cubic feet of space
In (2007) we where generating 477,728,646.84 cubic feet of space per day under ground because of removing 85,085,664 barrels of oil per day. What fills or replaces the oil that is take from the ground. Oh they say to cover up, water. But that a little far fetched, and without going into details, hard to believe. No the days the oceans crack open or the morning you hear on the news, Saudi sank and under 10 feet of water. Believe me, oil will hit the roof.
