humanicides

Noun

humanicide (countable and uncountable, plural humanicides)

1. The destruction of the human race.
   • Short of omnicide, the killing of everything, and of humanicide, the destruction of the whole human race, which a collapse of the ecosystem would bring about (a nuclear World War III could be a shortcut), surely genocide must be considered the supreme crime against mankind.1979 January-March, Christian Bay, “A human rights approach to transnational politics”, in Universal Humand Rights, volume 19
2. A substance, person, or group that exterminates people.
   • You will pardon me for telling you just what I at the time thought, viz. that you needed a "humanicide" as badly as you needed insecticides.1895, Ohio State Horticultural Society, Proceedings of the Annual Meeting, page 104
