I'd just like to say, that the planet don't need crude oil for its transportation needs. At all. Even with hybrid engine solutions, current gasoline and diesel can easily be swapped for the likes of renewable ethanol and cooking oil from biomatter. For cars, semis, planes, ships, every damn thing imaginable. And that's excluding the simplicity in gaining more and more electricity from wind, sun, water and what ever hasn't been thought of yet. But ... you peasants are not gonna get those hippie-solutions untill the day there's absolutely no more fossil carbon dioxide left in the crust, and half the planet has become uninhabitable for human beings. 'Cause the engineers and politicians of the world don't want cancer.
