All world population fits in half of Luxembourg

It’s a general concern that our world lacks resources to keep up with current population growth.
However, surface area of our planet is not one of those lacking resources.

Check this out:

. In average a standing person occupy 0,36 m x 0,50 m of ground (=0,18 m2)

. It is estimated that current world population is 7.225.000.000

. If you join all world population in standing position you will need only 1.300 km2

. The Luxembourg area is 2.586 km2

 So, if you create a huge plaza with a surface area with the size of half of Luxembourg area, you could join there all world population in standing position.
