2. Increase in Average Human Age: This means that people are living longer than before, and if that is the case then population will keep growing
3. An expansive Age Structure of World Population: The world population will keep growing into the near future because it has an Expansive population pyramid which means that a larger percentage of people are in the younger age bracket.
