It took all of human history until the year 1804 for our population to reach its first billion. Now a billion new people are added every dozen years. In the industrialized world-Japan, Europe, and the United States-birthrates are falling steeply while the senior citizen population is booming. In this two-hour Earth Day special, NOVA explores these and other trends in the relationship between people and the planet.
