Alex Steffen over at WorldChanging argues that the "Hollywood idea of the Apocalypse" is bad for us. Why? Well, when people believe that we'll either avoid, or succumb to, a singular, catastrophic event, they feel like the future is out of their hands. After all, if the end is nigh (via climate change, Ebola fever, nuclear war, or whatever) what can anyone do about it? The die is cast.
In reality the world gets better or worse gradually (with some points of punctuation, of course) and there are things people can do to make the future better (or worse). Steffen's essay is an interesting read.
