The total world population in the year 1800 was 1 billion people. Today there are 7.8 billion people in the world. Year Global Population (in billions)
2017 7.511
2018 7.594
2019 7.700
2020 7.800
(a) Using the table above
calculate the average population growth rate over the past 3 years. (b) Using the growth rate from part (a), calculate in what year the world population will reach 9 billion people (round down to the nearest year). (c) List 3 stresses this rapid growth in population may put on the environment.
Data given:
(a)
(b) the average growth rate = 1.267 %
Therefore, the year in which world population would reach 9 billion can be calculated by following equation,
(c) 3 stresses this rapid growth in population may put on the environment are –
