There are currently over 7.5 billion people on earth. Within less than a century the population is expected to double.
People who can remember back to 1950 may tell you the world felt less crowded then, and it’s true, there were only two people for every four who live today. Around the year 1900, there were only 1.6 billion people. In George Washington’s time there were about 750 million people. In the time Jesus lived, there were only about 200 million people on earth, less than those just in the United States today. It is estimated that around 10,000 BC the total was only five million people on the earth, less than the population of New York City.
