This country is one of the safest in the world. We have no killer animals. We don’t have earthquakes. There are no major tsunamis. We don’t really have to prep for a huge natural disaster – and there’s very little you could do to prepare for a nuclear event even if you wanted to – so we prep more pragmatically. Suppose you lose your job and money’s an issue. Or the electrical grid goes out and the food chain goes down and all of a sudden every man and his dog is arguing over a bag of sugar. Do you have your own supplies? Do you have the means to cook? And what about keeping warm – could you make a fire? Some of us buy food through an app; groceries are delivered to our front doors. Do people know how to survive without electricity?
This author has taken the general guidelines and used those. This is the recommenations of various agencies. Having that gallon a day would be able to keep people in most climates alive but not thriving. While I agree one will need MORE water, this is the recommendations and a good place to start. Once a person realizes the amount their family NEEDs, they can add additional by saving soda bottles and washing and re filling those, to build a quick cheap supply.

There’s a really good app called Prep and Pantry. It allows you to create did inventories, including expiration dates. It scans the barcode too so you don’t have to enter it by hand. This helps me know what I have and lets me plan my meals around when food is expiring. I think it’s about $8, but it’s helped me save a lot of money by not throwing food away.
Any bulk meat I have set aside is canned. If I find a good deal on chicken or even hamburger I can it.I don’t have to worry about a power outage and the loss of a very expensive food item. I know canning isn’t for everyone but the convience of going to the pantry and grabbing a jar of chicken for a salad already cubed and fully cooked has made it all worthwhile. A couple weeks ago I found several packs of italian sausage at the store marked down because it had one day to expiration. I bought what they had, several green peppers, a couple onions. I now have a meal in a jar. All cooked ready to go. throw em in a pan to brown them and warm it all up. Sandwich ready
Though its light weight and long shelf life are ideal for navigating harsh conditions, freeze-dried food is probably most famous as a cultural curiosity: Like many Americans, I discovered it in a museum gift shop, gawking at the styrofoam-like ice cream that astronauts used to have for dessert. More recently, I encountered it at a disaster preparedness convention in Raleigh, North Carolina, where smiling, gray-haired preppers manned tables piled with plastic bags full of vegetables, meats, and stews.
