The discussion at the end regarding the moral and ethical implications of having kids is interesting. I struggled with this on an intuitive level having not run the numbers myself. However some friends also pointed out that maybe the world doesn't need fewer people but more smart ones. I think the choice to not have children is perfectly legitimate. There is plenty of social pressure to procreate if you're involved in a committed Heterosexual relationship. But it's a difficult problem to pose ethically. If I were the author I would have left that out. There be dragons in the ethics department.
