How big is the volume of humankind?
It seems from Wolfram Alpha that the average human volume is around 66.4 liters. The current human population is 6.93 billion people.
Therefore all humankind is 4.602 * 10^11 liters of stuff, which correspond to a cube with a side of 772 meters or a sphere with slightly less than 1 km diameter.
This roughly corresponds to a small asteroid, or a few skyscrapers (Wolfram Alpha tells us that it's 0.92 times the water in the Sydney Harbour, but it hardly seems suggestive to me, perhaps because I'm not Australian).
