Population Collapse Is the Biggest Threat to Civilization

Elon musk recently tweated quotaqo, population collapse is the biggest threat to civilization. i want to introduce a counter perspective, which is very much obscure compared to peterson and musk. This is from two academics who write in an academic journal called evolution and human behaviour. They argue that number of children you have is related to the number of children your parents and grandparents have. And their argument is essentially that fertilityat tends to increase. So i think a lack of people in large parts of the world will be a problem if africa still has boomy, booming fertility rates.
