We fight wars over it. We take it change culture from living off the land to monopolized "civilian" way of life then profit from this natural resource. My question is what is the purpose of oil being in the ground in the first place??? There must be a purpose. Maybe. Volcano lava was found to contain a substance that was the best body detoxifier the world ever seen but you could never deplete it because there is too much of it. But besides running our cars and fueling our homes what purpose does oil serve in it's natural state???
