Mankind, even with its self-destructive tendencies and weak links, is probably worth keeping around, especially when you consider that me, you, and everyone else in the world is a part of it. Sure, we’ll destroy ourselves eventually, but until then we should take comfort in the fact that overall, despite a few rotten apples, mankind is alright. After all, you couldn’t do better. Or could you? What if you had the chance to try? Would you sacrifice your only child to save mankind, essentially choosing between the world as we know it or a world as your sperm would know it?
