Most of the oil we use was made during a time period when the earth was much much warmer than it is today. A time when the planet was teeming with plant and animal life. The Carboniferous Period occurred from about 360 to 286 million years ago. At the time, the land was covered with swamps filled with huge trees, ferns and other large leafy plants. It seems that a warm planet is a good place to create biomass.
What better way to use the oil than to heat up the planet and recreate the earth as it was when the oil was first created thereby completing the cycle and guaranteeing the earth will never run out of oil. Lazs is of coarse correct that we will never run out of oil. The day will come when the alternatives are more economically viable to use but there will still be oil and more being made all the time.
It is arrogant of humans to believe that they can do anything to damage "the planet". It has shrugged off massive asteroids strikes and global vulcanizm. We can make it less hospitable for humans which means some will die off; from starvation, from disease, from fighting over what's left. And in short order there will be less of us and whatever minor short term effects we caused will snap back.
In the end we are all completely insignificant in global terms and the planet will carry on just fine until it runs out of the only thing it needs: the sun.
