Good lord people!
What about just a few seeds so you can generate a garden?
Some quick growing things. Many types of lettuces.
How about a sprout bag? You can have food in 3 days from a sprout bag.
It wouldn't be bad to have some extra "survival type" foods in an emergency.
For one thing, I recommend chia seed. It doesn't take a lot of storage space, it's cheap, easy, quick, immediate food supply.
As a matter of fact the Indians used it for survival food when they made long trips from the mountains to seashore to trade goods. They didn't have time to stop and kill buffalo. Heck...they may not even see any buffalo. They carried chia seed in their pouches and that, plus whatever vegetation they found along the way, sustained them.
Also, bee pollen and honey are survival foods. Honey needs no refrigeration. You can mix the pollen into the honey and it will be fine.
powdered carob has a lot of energy and is a food that can help sustain you in famine.
Also, I would suggest growing other foods that many people would not recognize as a food source.
Such as Yucca plants, amaranth, chickweed, purslane.
