Yes, but it's really inevitable. The important thing is, that the White race and its nations will survive (for the most part), bounce back (some more than others) and rise to prosper and dominate once again.
The world will not end, just change. Drastically so. And at least for Europeans, facing a population collapse of 1/3rd or more over a few decades is nothing unusual and nothing they cannot recover from. Only this time it will be 30% - 50%+ within a few years. A historically unprecedented mass death event. At least since the last turning of the ages.
And let's face it: a large part of current humanity is useless and unfit for survival, degenerate even. Nothing good will ever come from letting those continue to breed (which they luckily are increasingly reluctant to).
It's time for a new genetic bottleneck, which will come about one way or another. And those who make it trough to the other side will be blessed with a low population density, recovering nature and a generally much healthier, more natural lifestyle free of the pitfalls and plagues of modern civilization and globalism.
Also, death is the only constant in this world. And where there are great masses of individuals, mass death is only an inevitable consequence.
