What did Dr. Albert Bartlett mean when he said, "the greatest shortcoming of the human race is our
inability to understand the exponential function"? What will be an ideal response?
His point was that exponential population growth is commonly not understood. World population, for
example, quadrupled in the 20th century from 1.6 billion, in 1900, to over 6 billion, in 2000, and it
took only 12 years for the last billion people to be added to our population. Doubling times will
continue to get shorter unless population growth rates decrease. This trend cannot continue indefinitely
in a world of finite resources and living space.
