Is it feeling a little crowded in here, or is it just us? In November 2011, the UN predicted the world population had reached 7 billion.

In "The Next Billion," students try to predict when we will surpass 8 billion. Throughout the lesson, students discuss the reliability of their predictions, compare them to past trends and discuss social factors that affect population growth.
