The real problem is that 37 million is too big a number. Saying something would fill 10 or even 100 Empire State Buildings is relatable. Once you say 37 million ESBs or 10 billion swimming pools, you might as well say it's 10 quadrillion coffee cups full.

I prefer the examples higher up the thread of filling the Grand Canyon 9 times or submerging all of California to a depth of 100m.
