-Increasing are birth rate is only half the battle people of European descent only make up around 12-13% of the worlds population well None-Europeans not only make up the rest they also have a much higher birth rate that we would NEVER be able to match. So increasing the birth rate would not make much a difference, we will still be swamped by sheer numbers. We need separation, we need pure lands free of Non-Europeans, keeping them out of are lands would solve most of the problem; we would not have to worry about the birth rate then or at least not as much.
