non-natural childbirth, vaccines
Two related questions.
First, could C-sections and surgically-assisted births create a growing subset of the population who cannot survive "natural" childbirth?
Second, the CDC and other sites list over 30 recommended vaccines. In the same vein as question above, could this give rise over time to a subset of the population who could not survive without a battery of immunizations?
We all know the benefits of modern obstetrics and (some) vaccines. My question is about possible unintended longterm consequences--a distant future in which access to medicine is suddenly limited, for example.
