Answer the Question $4000 \mathrm { BC } - 2000 \mathrm { AD }$

Essay

Answer the question.
-The graph below shows estimated world population for the period 4000 BC $4000 \mathrm { BC } - 2000 \mathrm { AD }$ Note that the logarithm of the world population and not actual population is plotted on
the vertical axis. This means, for example, that when the graph reaches 7 on the vertical
scale, world population is $10 ^ { 7 }$ and when the graph reaches 9 on the vertical scale, world
population is $10 ^ { 9 }$ . Why must the graph be interpreted with care? If the graph is not interpreted with care
what misleading impression might one have of world population during the period 4000
BC - 2000 AD? Why do you think that the graph was presented in this form?
