World War Z chapter 9: Good-byes

Chapter 9, good-byes, is about how the world, and life, comes back after the zombies. The one part that stood out to me the most was when Maria was pregnant only to help populate the earth. Of course this is an idea that would be taken into effect, mainly because everybody turned into zombies and the human populous was lacing people, but it's still a weird thing to think about.
