Surviving the zombie apocalypse is relatively easy. Zombies are dead, slow and stupid. And they rot
, so they have a rather short 'livespan'.
In temperate regions it will take about 2 weeks for flies to fully convert zombies into more flies. During the zombie apocalypse flies are your friends. Decomposition: fly life cycle and development times - Australian Museum
In polar regions zombies simply freeze. They're dead, so their body temperature is the same as the temperature of the environment
. Freezing should not take more than a couple of hours. Once the zombies have stopped moving you can stick a carrot in their face and dress them up in a shawl and high hat.
In jungle regions the combined workforce of arthropods, worms, fungi and bacteria will reduce even the biggest zombie to compost in no more than 3 days. Tomatoes grow very well on this type of compost.
In deserts the sun will turn zombies into extra crispy jerky in just under 5 days. Although the jerky isn't edible, it can be used as fuel
for fire or building material.
When you find yourself being pursued by a zombie horde: just walk slightly faster than the horde and you should be alright.
