Voluntary Human Extinction Movement – advocates for current humans live long, happy lives, but to choose not to have children. Until eventually there are no humans left. That is different to the ideas presented here, where we want a sustainable number of humans to exist in harmony with the rest of the planet. We also want to actively encourage people not to breed because we will make our civilization unpleasant to live in.
