Consider that Bangladesh has a surface area of 143,998 square kilometers. How long would it take, at
a growth rate of 1.6%, for there to be one person for every square meter of land surface? What is the
implication of this relative to carrying capacity? What will be an ideal response?
143,998 square kilometers contains 153,998,000,000 square meters. In order to get from a population
of 161,084,000 to a population of 143,998,000,000 it would take a little over 440 years (slightly more
than 10 doublings); the carrying capacity will be reached much sooner.
