Why hasn't there been a zombie apocalypse?
There are 3 possiblities:
1. It may not ever happen at all. Zombies may not exist.
2. It might not be the time. Maybe in the future, but most likely not soon.
3. It may not have happened yet because no scientist has been able to create a zombie virus.
There is a video from Vsauce about zombie bugs, which shows what could be a zombie virus.
What are the release dates for Not Another Zombie Apocalypse - 2013 That Girl Did What to a Zombie 1-1?
I personally think that there will NOT be a zombie apocalypse. On the Mayan Ca lander ,it says that the world will end in December 21,2012. I don't think that the world will end, nor there will be a zombie apocalypse. Although, I think that there might be a natural disaster, such as a earthquake, a hurricane, or a tornado.
When the Zombie Apocalypse comes, hop into a jet and go until you break the sound barrier. after that, scream, "Holy S---! There are zombies in the jet!" You have to be truthful with the aforementioned comment (zombies must actually BE in the jet), and Ta-Da, you have a Sonic Zombie Apocalypse. Hope this helps.
