Answer 1

They didn’t learn. Half of third world still hasn’t learned. And yes, it means a lot of sickness and early deaths. There’s a reason average fertility rates used to be like 6-8 children per woman, yet world population remained pretty stagnant for thousands of years and that reason involved a lot of dead children.
