What is the maximum people that can live on Earth?
They conclude: “recent predictions of stabilized world population levels for 2050 exceed several of our meta-estimates of a world population limit”. A 2012 United Nations report summarized 65 different estimated maximum sustainable population sizes and the most common estimate was 8 billion.
How much percent of the world’s land is inhabited?
So on the one hand, you could say from these results that 10\% of Earth is inhabited by humans. Or you could take a more glass half-empty view and say that 90\% of Earth is covered by humans – either populated or connected with an ever-expanding network of roads, train tracks, highways, farms and industrial land.
What is the maximum carrying capacity of Earth?
Earth’s capacity. Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people.

How many people will the Earth’s population be capable of supporting?

How many people does the Earth really hold?
Scientists disagree not only on the final number, but more importantly about the best and most accurate way of determining that number—hence the huge variability. The majority of studies estimate that the Earth’s capacity is at or beneath 8 billion people.
Can you fit the entire population of Earth into a cubic mile?
If you really wanted to, you could fit the entire population of the Earth into the corner of a cubic mile. Space isn’t an issue. The only overcrowding we have on Earth today is in big cities, where more and more people keep moving to try to find non-agricultural or mining employment.
