I don't disagree.  Clearly the overall numbers have increased.  But in the West, the population would be dwindling were not it for other parts of the world moving into the West.   

So in essence, the non-feminist world is creating the babies and the feminist Western world is importing them.

In terms of a solution, someone needs to think of an idea that will encourage women in the West to reproduce without giving up on the values of feminism.  I'm not sure what the answer to that is.
