Many years ago I read "Death of the West" by Patrick J. Buchanan and he wrote about the population shifts and declining birth rates, especially in the West. Back in early 2000 there was no "vaccination" to help decrease populations at the levels we see today, but he was entirely correct about the population shifts happening throughout the world. I think what would be even more eye opening would be to see these statistics broken down by race. There is a world wide genocide taking place and targeted population replacements that are happening, especially in Europe and the US. After looking through his more recent books, I think I need to read some more of his books...he is a very good writer with great sense of what is going on in the world.
