19The Lack of Vegetation
Over the entirety of The Walking Dead’s run, audiences have seen the survivors at the core of the show travel extensively and they’ve settled in one place after another. On top of that, they also have found themselves forced to battle a series of different villainous groups. Given all of
these events, it is abundantly clear that a significant amount of time has passed since zombies first took the world by storm. Given that fact, by this point in the series, there is something else that should have taken over much of the world, vegetation. At the very least, most places should have incredibly overgrown grass without someone there to cut it back.
