Bio-atheism is a branch of atheism that aims at preserving atheism for future generations via human procreation. Atheist birth rate is very low and dropping fast due to human hedonism and individualism, effective birth control and anti-STD drugs, and anti-natalist ideologies like ChildFree, MGTOW, Herbivore men, and Zeta male ideologies. If the decline of birth rates in atheist families is not stopped, human society will become dominated by religious people with high fertility rates and atheism will cease to exist.
