What you need to know

  • The human population grew extremely quickly and is still growing.
  • A population can keep rising for a while even after the birth rate starts to fall, because many people are still of child-bearing age.
  • Natural change is the gap between births and deaths, not the size of the population on its own.
  • The frightening question in the title is what the lesson examines, and the growth is not presented as an automatic disaster.
