The end of human civilization may be occurring within our lifetime. So children born today may be fighting in wars over water or killed in nuclear attacks twenty years from now. They may not be able to survive these events. Meaning, they won't have children of their own.
If the damage is severe enough, the human population might bottleneck to where we won't have enough genetic diversity to repopulate the earth. Sort of like how cheetahs are going extinct because they're all born with the same genetic disorder and there aren't any cheetahs without it.
Would you mind elaborating?
