A badly distributed world

There are 6 billion people on Earth. That is 6,000,000,000.

Imagine a plot of land 20m x 20m, that is 400 square metres. I think one person can have a very decent sized room, say 10m x 10m plus a garden with a pond in the remaining 300 square metres. Enough to keep a few animals, grow some rice and vegetables and a few trees and plants.

If each human on Earth were to have 400 square metres, it would need 2400,000,000,000 square metres of land. That is 2.4 trillion square metres.

One square Kilometre is 1 million square metres (1000 x 1000 metres). So, 2.4 trillion square metres is 2.4 million square Kilometres. 2,400,000.

That is a stretch of land that could be, for instance, 2400 Km x 1000 Km.

Smaller than Mexico.

Who says its a crowded world?

Thats a good way of putting it, after living here in Philippines for almost 2 yrs its hard to believe that all humans could fit in 1 country if we were distributed better!
