Earth may only be a tiny blip on the map relative to the entire universe, but for our purposes, it’s pretty darn big. Of course, the vast majority of earth – about 70% – is comprised of water. Taking that into account, the actual area of land on earth is estimated to be around 150 million square kilometers.
That being the case, Life Noggin recently set out to examine how many human beings the earth is capable of holding; not in a physical sense, but more in the sense of how many people can be sustained by the Earth’s finite resources. Today, the earth’s population checks in at about 7 billion, but that figure will only increase in the years ahead thanks to improvements in medicine and other health-positive factors. In fact, it’s estimated that the human population by the end of the century will be 10 billion strong.
