It may not need to be.
Population growth is slowing overall, and is predicted to stop by the end of the century.
It's almost inevitable a decline will follow, leading some statisticians to assert that we are heading in the long term for extinction.
Apparently, once a trend is set, it's very hard to reverse it.

Hans Rosling had a great presentation on population growth - not sure if it is on YouTube or something.
Essentially, it appears that the main driver for population growth at the moment is people living longer, not fertility rates.
Fertility rates in almost all parts of the world outside sub-saharan Africa have been dropping sharply.
As @mudsticks mentions, the best way to reduce fertility rates is for improvements in health, education and opportunities especially for women. It has been the case in Europe, Asia and Latin America, and such a marked drop that places like Brazil have dropped from around 3 to 1.7 children per woman, which is starting to create issues of its own (or at least a societal change). South Korea has dropped to around 0.9.
