That’s kinda a huge problem. So Africa much like the 1800s in first world countries, you’d have like 9 kids because maybe 3 would make it to 18+. When vaccines, antibiotics, ect were discovered suddenly only like 1 or 2 of these 9 kids died before 18. So we stopped having a ton of kids and had kike 1-3 typically.

In Africa while maybe being behind the are benifiting from medial advances and less kids are dying. But now because of that they’re still having 9 kids and they have no food or water because of overpopulation among other things.
