Four hundred years ago, the number was over 500 million. But at the beginning of the 20^th century, the world’s population was about 1,700 million. In 1970, the number was3,600 million. In 1990, the number was five billion. A UN report said that the world population had passed six billion by the end of the 20^th century. This was just ten years after it reached five billion. By October 31, 2011, with a new baby’s birth, the world’s population has reached 7 billion. But another billion is coming by 2025, and the total will reach 10 billion before the end of the century.
