In “How Big is Space?,” a recent episode of Earth Unplugged by BBC Earth Productions, they examine how much space we need to live, how much space there is on Earth, and how much space there is in the vast reaches of outer space. According to the video, if you were to spread every human evenly across the Earth, everyone would get 17 acres each. That’s a lot of space!
