In the past century the earth's human population has nearly quadrupled, growing from 1.7 billion in 1900 to about 7 billion today. By 2050, it is estimated that the global population will reach 10 billion. In 1968, a young biologist named Paul Ehrlich wrote a best-selling book called The Population Bomb, which sparked an ongoing debate about the dangers of overpopulation. He argued that population growth was destroying the ecological systems necessary to sustain life.
