Since the topic of zombies was constantly being brought up by the zombie enthusiasts in my environmental studies class I did an optional talk/discussion on several of the ways nature has already "zombie-fied" the world a few weeks ago. It of course, included some of the things discussed in this article. That being said, does anyone else worry about how desensitized the world is becoming to everything violent? The popularity of apocalyptic scenarios is a little alarming. The world is terrifying (and awesome) all by itself. Why do we need it to come crashing down around us?
