What is it with people and their attitude that we can't know anything? Do you really believe there are giant pools of oil somewhere that we don't know about or will simply discover just in time? We can know that land masses not in politicaly unstable areas have all been prospected - no oil there. We have checked most off shore contenental shelf areas - some oil. What is discovered or tapped are ever smaller pools. Our finds grow smaller and rarer all the time and you still think we will stumble upon a saudi size find?
come on you can't know... and Yeah I do...
