Nobody cares about how much is left. All people care about is how much it costs. 'Sustainability' it is a long word which is easy to spell right, but in America it is a foreign concept.
Listening to this guy I realized that people reify the oil market. Inside the box, we can't think outside of it. The presenter makes 'the oil market' into a thing which we have a responsibility to take care of. Like the oil market was a living thing. Like it was a pet rock with feelings to worry about. As if the life of a useless eater was a god-given right. That god only cares about our current generation and not what comes later.
