Every survivalist has their 'favourite' disaster. Here is a list of my top three.
3. Dirty bomb
2. Meteor impact
1. Bee extinction
When I say that bee extinction is my 'favorite' disaster I do not mean that is the most likely or even that the incident is the worst disaster imaginable. I am talking about a combination of the two. I am looking for situations that are both preventable and reasonably likely. I do not intend to guard against events that are either-
a) Absurd (anything by David Ike or L Ron Hubbard).
b) So destructive that nothing can be done (black holes, supernovas and so on).
