very interesting article. I thought about the weather, but not the fact that birds would be there ripping the zombies apart.

assuming it wasn't a viral outbreak AND zombies move "traditionally" and not "28 days later" style (as mentioned)

28 days later or 28 weeks later has animals eating dead humans. Remember the crow dripping blood into that father's eye?

Oh yea.....but that would aid in spreading the disease more than wiping out the zombie population, no? Interesting point by the article nonetheless.

true. more like rabies in that case.

Insects will have a field day with all of the dead things around when the zombie apocalypse comes.

And ultimately, giant spiders will be having a buffet.

Imagine a zombie coming at you that has spider babies leaking out of it?

I'd be more afraid if the zombie was harboring ticks or parasitic worms, spiders are my friends.
