> we found that getting pregnant early actually is a detriment to the individual, their immediate surroundings, and society as a whole

You are citing a source that talks about unintended pregnancies (often as a result of sexual abuse) in developing nations. With nearly half of those being prematurely aborted in some (medically safe or not) way.

I’m inclined to believe that the support system throughout most of history was better than what these girls get.
