Extinction Rebellion activists are claiming that ending births is necessary to save humans from extinction because of climate change:
My observation is species go extinct when they fail to reproduce. No children means human extinction is assured within a generation or two. The logical extension to no births would be to prevent extinction by mass suicide or even mass homicide.
Of course, banning immigration from low-emitting countries to high-emitting countries is also necessary as well, otherwise the population in high-emitting countries could continue to grow even without births.
The idea of preventing extinction by failing to reproduce seems ridiculous to me. How humanity can survive without children?
