    The term "barrels" of oil is just a unit of measure. Just like gallons of gas we don’t buy them individually. Nice try.

    your question is like asking who makes the gallons for the dairy farmers. except in this analogy, milk is actually EVENTUALLY sold in one-gallon containers.

    Your efforts would be best directed toward a plan to get the world off the rampant and deadly usage of fossil fuels and all the destructive attributes attached to that industry.
