7 Doomsday Scenarios You Probably Shouldn't Worry About (And 2 You Really Should)

4. Zombies

Yes, yes, the fact that zombies are the supernaturally reanimated corpses of the dead is probably the biggest hurdle in the way of a zombie apocalypse, but even if we accept that aspect of it for the purposes debate, the shambling undead are still wildly unlikely to bring about the end of days.

The matter of exactly why and how a zombie outbreak would fail miserably has been roundly and gleefully covered in all corners of the internet. Cited reasons range from the laws of thermodynamics (zombie ice lolly anyone?) to the law of the jungle (i.e. zombies are walking dog food), but one of the major reasons a zombie apocalypse would be stopped before it can start is that this is a foe that is completely unarmed.

It doesn't really matter how fast or bitey your zombies are, history tells us that when you pit people with guns against people without guns, things tend to go badly for the latter. Zombies don't even use melee weapons and they don't appear to be able to throw, so even if you don't own your own gun which, given that 10% of the world population does and that there are roughly 1.126 guns per person in the US, is unlikely, the military certainly does and they will be able to use them to great effect.

This, combined with the many and varied obstacles in the zombies' path to world domination, would mean that the un-dead would be swiftly dead-dead before the opening credits rolled.
