What should I prep for?

[Paul]

I'm listening to the radio, reading the Internet news, and reading to all sorts of thoughts, expert opinion, and paranoia about how the world is going to end SOON.

So far it looks like:

Economic and Political
The EU Collapses
Total Economic collapse of all the worlds finances.
Middle East War (Israel v Iran) drags in the US, Russia & China, that turns into WW3.
Religious wars i.e. Moslems verses Christians develops into WW3
The Yanks invaded us and turn us into their 53rd state
The Germans assimilate us we become part of their super state and have to learn German.
The New World Order establishes itself and we all have to wear grey.

Global Warming causes
A pandemic caused by mosquitoes.
We all become zombies
Food and water shortages

Other Global tilts
The oil drys up.
The Myans got it right!
The magnetic poles reverse
Solar storms knocks out all electricity
The world gets hit by an asteroid
Super Volcanoes
Global Tsunamis
Alien invasion.

It's all very tiring.
What exactly am I to prep for?
World events or my local Tesco running out of food?

Go one, someone sort the paranoia out from the real worries and give me some sort of direction to my prepping.
Global or Local?
