Oil is honestly an amazing product, chemistry wise there is so much we can do with it and energy wise it's a extremely concentrated and easily transported form of energy.

Energy wise one liter of oil is equivalent to 10 person working for a day !

I repeat, using one liter of oil is like having 10 "slaves" working for us for a day.

Its easy to see why oil became the base of our modern civilization, and easy to see why we don't manage to stop using it even though it's destroying us.
