Human Greed

Another theme that I have noticed while reading further into Boneshaker is the factor that human greed plays in most apocalyptic works.  In the case of this book it is greed in the form of wanting to drill through the Alaskan ice to find gold.  It is rare that any author or film-maker will create any apocalyptic work about a human-caused event without greed being the reason that the event was undergone in the first place.
