When I was in high school economics, we did this thought exercise to figure out how much goes into manufacturing and delivering something, say, a thumb tack.
So you list stuff like "the plastic box it came in" "the paper label on the box" "the ink on the paper" "the paint on the thumbtack itself" "the metal in the thumbtack" and build a tree that goes from the thumbtack out to "the rubber in the tires of the truck that brought the raw metals to the refinery to make the steel" and so on. It was an interesting exercise in just how connected everything is.
So it's only mildly mind blowing to find out that it takes 250 liters of water to produce 1 liter of coca cola.
as a side note, that image comes from Sharad Haksar and it's getting him in a lot of hot water with Coca Cola
