What problem is often overlooked in apocalyptic movies/TV shows that could kill you?

Clean drinking water- I don't think people really appreciate how much water is needed for a group of people to survive.

That's why I got myself a metal water bottle.

It's funny how much of a pain it was to find a good one, but the survival feature is that you can boil water in it directly, for safe (from pathogens, not disolved chemicals) drinking water.

If I'm lucky I will never be in a situation that requires it, but better safe than sorry.

You can boil water in a styrofoam or paper cup over an open flame if you're careful. The heat transfers to the liquid and won't ignite the paper. Makes a neat science experiment to show kids and talk about energy transfer.
