The No-Babys Crisis in the World

The only region of the world that will have positive population growth on Earth is sub-Saharan Africa. Korea right now has a 0.78 total fertility rate, meaning if those conditions were to hold throughout a woman's lifetime, the number of kids she would end up having is less than one child per woman. For every 100 living Koreans, there will be six great grandchildren,. It's not comparable to the small pox epidemics in the New World and it's going to happen over three generations.
