Myth: Earth is Close to Overpopulation

This is a myth has been around since the 18th century, but the world is a really big place with plenty of space.

Let's look at how much land it really takes to hold 6 billion people. To give you an idea, consider the small nation of Japan, which has about 143,000 square miles of land. One square mile has 27.9 million square feet. Japan has a total of about 4 trillion square feet, enough to give each person on earth 670 square feet. If we housed people in families of four in simple two-level buildings (8 people per building, one family of four per level), each building could be on a lot of over 5300 square feet.

Using the American average of 8,000 square feet to house four people, the entire population of the planet would fit into a space the size of Texas and Nevada combined or less than the state of Alaska. That leaves a bunch of unused space for growing crops, sailing, and going on vacations.
