  The solid line in this graph shows estimates of the size of the world's population over the last two millennia. The estimates from 1800 to 1991 are based on more accurate data than those before.
  The dotted line shows what would happen if exponential growth continued to the year 2100.
  
  As you can see, the world's population has been growing exponentially (except during the years of the black death). How long will it continue to do so? (Since the graph was drawn, the world's population has reached 6.9 billion; that is, in 2010 we are still on course.) But can it continue indefinitely? Surely not

  •  Some demographers (students of population) say we have already exceeded the number. Others say the earth can hold billions more.
