With the world's population projected to swell to 11 billion by 2100, one might wonder if there's enough room on the planet for so many human beings.
The answer, according to a new map, is yes, at least in terms of physical space.
Created by data journalist Max Galka of Metrocosm, the map presents a startling picture of the current imbalance in the world's population density: half of us live in the yellow areas, half in the black.
The map was created using gridded population data compiled by NASA. It's made up of some 28 million "cells," each comprising an area of approximately nine square miles. The yellow areas include cells with a population of 8,000 or more people; the black areas include cells with a population of fewer than 8,000 people.
Put another way, the yellow cells have a population density of 900 people per square mile, but make up only one per cent of the Earth's surface area.
Unsurprisingly, Canada presents as mainly wide open space, with just a smattering of yellow cells representing our major cities:
Evidently, there's an astounding amount of space on the planet to accommodate future humans, particularly in areas where the greatest population growth is projected to occur, like Africa. However, as experts have pointed out, the concern is not where to put our future generations, but how to feed them.
