the most basic what we need and those mostly in the urban areas have no clue where to get it.
Water.
Ask those in the urban areas where their fresh water supply is for them to live on and where could they go to get water and food if need be and they are clueless.
Here we have animals, hunters, fish, lots of fish, know where various water supplies are and those not so close if something went bad here.
I’d be hard pressed if things really collapsed. I do however have the means to purify enough water to last me longer than I’d survive; and I know where there is water enough to purify.
What i don’t have is the means to hunt, fish, or otherwise provide food. My family carries our emergency supplies on our backs (that’s a joke about how being obese is a survival technique).
