How much space do You need, if You like to call all of the population of the Eath in one place?
At this moment, about 7.5 billion people live on this planet and it's growing in every second!
Let's count with 7 500 000 000.
Give 1 square meter to everybody. It's about 3.28 square feets. That is fairly enough.
If everybody stand in strate line, the will be long enough to take more than 187 around the Earth!
But we like to call everybody to the same place.
That will take an almost 100 km/60 mls wide circe!
Let's see how is it looks like on the map!
