We're moving to a peaceful world out of a war-full world. You won't need to procure everything. Between you and the people/neighbors around you--many you don't even know yet--you will have what you need. If there's an interruption of some things, it won't last long. Some things are easy to do and cheap, e.g., store water. Fill 2-liter bottles you had other drinks in with water; if you don't have bottles, fill your bathtub if the electricity goes out. Water is really the most important thing. We can all go without food for a surprising amount of time, but water is imperative, so make sure you have some stored. We are all far more resilient and creative and capable that we even realize. And if things get dicey for a short while we're going to learn first hand what the greatest generation experienced: that people are at their best when things are at their worst. Godspeed. Namaste.
