its finite...
Back about 150 years ago when oil was "discovered", the number of people on this earth was far fewer than now. Since that time, oil has been guzzled, guzzled, guzzled at an alarming rate.
Believe it or not, the core of Earth is not a sloshing vat of oil. Oil, like diamonds, gold, and countless other minerals is not in infinite supply. Someday we will run out of it, or the cost of exploration for it will be prohibitive and damaging to the environment.
I ask again: Why can we not explore alternative fuel sources now while we can?
