What Global Risks?

[Scythe13]

The more I try to mitigate against a worst case scenario, i.e. TEOTWAWKI, the more I am prepared for a lower level SHTF scenario. Which seems pretty clear and simple logic.

However, the more I think about it, the less I can imagine happening that would cause an EOTWAWKI type situation.

Think of it like this, what kind of global catastrophes are possible in which a person could survive, and the world was not able to provide assistance?

I look at things like a nuclear bomb going off and causing an EMP. Thank goodness for other countries that would provide aid. Same for major situations.

Large scale events will happen, and the majority of the time the 'global community' lends a helping hand.

What large scale events do you foresee that could result in no outside aid being provided or available?
