I'm not sure how many of you seen the Preview over the TV for the History's channels tv series Life After People.
Watching all those video's got me thinking, how many of those disasters were more likely then the others? Since I have a lack of faith in humanity as a whole I'd have to say a Nuclear Winter. Or Possibly some type of plague.
Note that if you don't want the show ruined then you probably shouldn't watch the little clips they give. But I think it's a show worth watching.
Discuss what you think is more possible to destroy human life? It could be something the show gives, or something else entirely.
