According to a newly-released estimate from the UN, humanity is on track to grow to a global population of 11 billion people by the end of this century. Currently, there are 7.2 billion people on the planet and we're growing fast.
The question is, when will population expansion slow down and level off? Some demographers say these UN estimates are too high, because urban populations have extremely low reproductive rates - and the world's population, already more than 50 percent urban, is expected to be 67 percent urban by 2100.
