Antinatalism or anti-natalism is a philosophical view that values birth negatively. Antinatalists who defend this view argue that human reproduction (and some others to produce other life) should not reproduce because it is morally bad. However, the advocates of the idea formed various ethical foundations for antinatalism in scientific and literary articles. Some of the earliest surviving clear and conclusive statements of the idea that it is better to be unborn come from ancient Greece.
