Elon Musk on Population Growth

The world population growth is 0.85%.  In the developed world (OECD countries), it’s about 0.5%.

It’s not credible to me that our civilization is threatened by this. But if I were concerned, I’d ask a scientist whose life’s work is studying this phenomenon.  Why anyone could possibly care what Elon Musk thinks about Earth’s population and climate change is beyond me.
