Given the demographics of the Slavic regions (the ferility rate is about 1.5), that number leaving the home Slav counties, might empty the place of a certain mammalian species, namely homo sapiens.

Again you are assuming the Russian birthrate stays EXACTLY the same for over 40 years, that is avery BIG assumprtion.

Anyway, Ukraine, Belarus, and Moldova have a combined population of 206 million people, so 20 million people immigrating wouldn't be that catastrophic.
