Many years ago, I had a coworker (26F) who had fallen pregnant. Towards the end of the gestation period, and after the terrifyingly short maternal leave (American health care is awful), I asked her if it was her first child. She tells me that it was not. It was her 6th! She'd been effectively in perpetual pregnancy since she was 20, and had literally tripled the consumption her family was going to have on the world.
How incredibly selfish is that? We already have 8 billion people in the world -- if everyone did like she did, then there'd be 24 billion in a single generation and no planet left. It was that day I decided to have zero children. I needed to balance out those who would over populate with no remorse.
