Many of us drive a car, trucks get driven each day and many other machines use gasoline as well. This gets pumped out of our earth continuously, making earth bit by bit more hallow. Not a real calculation, but seeing how many trucks I see just in my small country (The Netherlands) and extrapolate to the whole earth times the average gasoline usage per hour.. we should be thinking about small cities in cubic meters per day of gasoline usage.
That made me wondering.. What is the number a bit more exact? And could you give a relative estimate to compare that number to (like a football stadium).
I don't care for an error margin of 5% or numbers from 2013. Just want something to 'grab' and get an idea.
