Simple steps

1. Japans Nuclear Reactors blows a shithole
2. The remaining reactors blow a shithole from the explosion
3. This creates a bigger asplosion
4. Nuclear Radiation in the shitloads(Cheyrnoble, can't even go back 30 years later)
5. Nuclear Radiation travels through world winds to the pacific ocean, reaching California, Oregon, etc.
6. All sealife in pacific ocean is infected, if not infected, will eat a fish that is infected and get infected.
7. Fish are fished, eaten by Americans, causing glanal cancer and continuous cancer caused by the amount of fish you eat (fish is for ****)
8. Low fish levels (death by radiation) = overfishing in east coast of america.
9. Overfishing means low fish levels and therefore massive death of sealife in the pacific and atlantic
10. Loss of an important food source, economy goes down, loss of many jobs, etc.
11. America gets pissed, world takes sides
12. North Korea, being the bitch they are, nukes the world in December of 2012.\


TL;DR VERSION

japan sucks and 2012 happens
