The following graphs (fig-1 and fig-2 below) show the world population in millions from 1000 to 2010 and the world population growth rate in the 20th century. Based on this information, which of the following statements is correct? The world population did not grow much from 1000-1700, after which the growth rate increased sharply. The world population continues to grow at an increasing rate. There has been a 600% increase in the world population over the past 200 years. The graphs suggest that the world population will start shrinking in near-term.
