Hopefully, you will be able to bug in for an extended period of time. Having bottled water stored away will help ease the burden when you are getting your footing in tough times. You should have a minimum of two weeks’ worth of bottled water stored away, but as much as a couple of months. Again, if the emergency is short-lived, this will be enough to get you through.
I have had my own Big Berkey system for at least five years now. Even if I have friends over who have no idea about prepping, they are interested in it for the fact that it provides clean, healthy, filtered water. I use the Big Berkey specifically because it uses a high standard of filtration to remove bacteria, parasites, mercury, lead and the high amounts of chlorine that is in my local drinking water and I don’t have to change the filters as much as I do with other filters. Safe to say, once people start filtering their water they notice the taste difference straight away.
What programs like Doomsday Preppers have accomplished, or at least contributed to, is turning sometimes well-informed, sometimes totally unwarranted paranoia into a booming prepper-industrial complex. Each year, swap meets pack hundreds of convention centers and fairgrounds across the nation—they’re like camping shows with a dose of military surplus and hands-on instructional sessions. The September 2017 Kansas City Survival Expo & Gun Show, for instance, had tips on seed saving, “Overcoming 900 Health Diseases” and “A Devastating Street Self-Defense System.” The latter was taught by Norman Cantwell, who inspired Patrick Swayze’s character in Roadhouse. You get the feeling that he and Steven Seagal would be friends.
I sincerely feel that the best of all of us comes out in a disaster, with exception to a few. These few are the ones that this article does not or should focus on. Avoidance of perspective team members should be steered more by ethics, integrity and morality. I personally avoid thieves, liars and evil-hearted persons, and lastly the drama queens or snakes (team busters). Everyone else is trainable, deserving of a chance and usually becomes a viable team member in a short amount of time. But back to Powderkeg’s comment, “I can’t save the world, only my family.” This is another one that wasn’t mentioned in the article – The Save The World or Everyone Prepper.
I would agree that the moral ground of choosing to not have a firearm is great for some people. I have a family and am prepared for our needs with supplies and learned skills and would not expect to need assistance of others. I am currently working on extra supplies that I might be able to distribute to others in need. I like to help others and do not see the world as an evil place. Unfortunately with a catastrophic event law enforcement is often not available. History and current events in less “civilized” areas has proven that without law then anarchy and predatory animals are often unleashed. I feel that it is my moral obligation to protect my family. If I took the stance that I would go firearm free for moral reasons then I don’t think that I could live with myself if I was powerless to stop thugs from overpowering me then stealing our hard earned supplies necessary for our survival and then brutalizing my wife and young daughter when I might have been able to stop it with force. If accepting the risk of being less able to protect your family is acceptable to you and your family for moral reasons then god bless you and I support your decision. Could I live with the “stain” on my soul for protecting my family from predatory animals using force? Yup. How many “stains” could I tolerate….depends on how many predators and how many bullets I have. I do not live in fear and do not think that my commitment to my family protection as a husband and father makes me psychotic, paranoid, pathetic, a coward or a sociopath and feel slighted at the suggestion otherwise in your post. I would say that each of us must make the moral decision themselves about use of firearms for protection. I don’t judge others decisions and wouldn’t expect others to judge mine. I think I am a realist. A protective firearm can be like a fire extinguisher- you don’t have one because you want to use it or expect a problem but stuff happens.
For global catastrophic risks the costs of food storage become impractical for most of the population  and for some such catastrophes conventional agriculture would not function due to the loss of a large fraction of sunlight (e.g. during nuclear winter or a supervolcano). In such situations, alternative food is necessary, which is converting natural gas and wood fiber to human edible food.
Below are two Prepper Supplies Checklist resources. The first is a free PDF of the original 17-page preppers supplies checklist. Over the years, I’ve collected feedback on how to improve the list and compiled the updated preppers supplies checklist into a book. The book is a 35-page “Preparedness Plan Workbook”. There are 9 categories of preparedness that are covered: Water, Food, Warmth, Light, First Aid, Hygiene, Communication, Financial, and Protection/Hunting. The Food & Water Checklists include formulas to determine how much of each you will need depending on the size of your family/group.
It’s impossible to carry all the food you will need for a week unless you’re eating very high density proteins like nuts. Nuts and dried meat are two of the easiest off-the-cuff meals. Canned food has a lot of water that is wasted during the cooking process. Stay away from heavily flavored or salted nuts. The amount of salt present in the unsalted nut mixes is still sufficient enough to replace electrolytes.
