- Best estimate - High projection - Low projection 26. The graph at the right shows three UN scenarios of future human population growth (in billions). Which of the following most accurately describes this graph? a. We will reach carrying capacity before 2050. b. Two of three scenarios assume population growth rate in 2050 will be less than in 1970. c. Annual growth rate has been declining since - 1970. d. Current and future growth rates have little influence on future population size. e. Population scientists cannot make reliable population predictions for a population that has barely been studied: more research needs to be conducted. 1950 1960 1970 1980 1990 2000 2010 2020 2030 2040 2050 Year Figure 1.
