Summary:
Earth is a finite place. The more people who inhabit it, the more they must compete for its resources. Although human population has grown steadily, developments in recent decades have been encouraging. Globally, women today give birth to an average of 2.5 children, half as many as in the early 1950s. In 40 percent of the worlds nations, the fertility rate is at or below the replacement level of 2.1 children per woman, the number at which offspring simply take the place of their parents.
