Of course, some "doomsday" preppers worry about even more exotic, post-apocalyptic scenarios mentioned in section 2.3, basically aiming for indefinite self-sufficiency. I don't think it's a particularly sound concern, but if the prospect of a civilizational collapse keeps you up at night, my best advice is to move to a rural community where you could farm, fish, or hunt. Some urban survivalists fantasize about trapping local squirrels, pigeons, or raccoons - but they would run out of food very fast. Small urban and suburban gardens are usually difficult to maintain and don't produce enough to feed a family, too.
The way I think of it is, it depends on the food. How long will it last once you open it? Will it last long enough once opened for your family to consume it before it goes bad. Also, only buy foods you know how to use and that you will actually like to eat. No point in buying wheat berries if you dont have the manual grinder to process it and if you don’t know how to cook with it. I have a family of 4 including 2 small children. If I store rice in a 5 gallon mylar, will we use it before it goes bad once it’s opened? Possibly not. So i put it in 1 lb mylar bags. We can pull out smaller amounts at a time.

While I’m a big fan of mylar bags and 5 gallon buckets, since my family is just two folks (unless extended family make it to the house in an event), I package things up in 1 gallon mylar bags before placing into the buckets. Allows me to open less food at once to the elements. Sure, I have gamma lids to apply afterwards, and the mylar bags I use have ziplock style tops for resealing, but the less I open to the elements at once the better it will last. To further extend shelf life of opened bags, I have a large supply of small silica gel packs that I can toss a few into open dry good bags. Once I finish the bags I can reuse the packs by gently heating in my Sun Oven.

A veritable industry has sprung up around the prepper movement. James Rawles, author of the non-fiction book How to Survive the End of the World as We Know It and a pair of best-selling novels on survival, says 130,000 people regularly read his survivalblog.com, where he and numerous contributors provide tips on how to prepare. The former Army intelligence officer has 40 advertisers selling everything from seeds to silver, and 30 more advertisers on a waiting list.

Of course, some extreme preppers will settle for nothing less than a military-grade gas mask rated for chemical, biological, and nuclear warfare. While it is true that such masks offer much better protection against nerve agents and similar extremely harmful substances, it's not a likely concern in most parts of the world - and either way, it's doubtful that you would have enough time to suit up once the symptoms kick in.
According to Hobel, shelter is your first priority. Lay down cardboard and other materials to insulate yourself from the ground. (Even in summer, the ground can have temperatures that lead to hypothermic conditions.) Use tarps, blankets, pillows—whatever you can find—to build the shelter on that layer. It should be as low to the ground as possible, and you shouldn’t be able to sit up when you’re inside, Hobel says. Other than the airflow you need to breathe, block all openings to keep cold air from coming in. It’s a matter of conserving heat. A lot of people don’t realize that their bodies are heat sources, Hobel says. You’re almost 100 degrees. Trap that heat around you instead of letting it rise in a tall shelter, and you won’t need a fire to stay warm.
In building Reddit, a community of thousands of discussion threads, into one of the most frequently visited sites in the world, Huffman has grown aware of the way that technology alters our relations with one another, for better and for worse. He has witnessed how social media can magnify public fear. “It’s easier for people to panic when they’re together,” he said, pointing out that “the Internet has made it easier for people to be together,” yet it also alerts people to emerging risks. Long before the financial crisis became front-page news, early signs appeared in user comments on Reddit. “People were starting to whisper about mortgages. They were worried about student debt. They were worried about debt in general. There was a lot of, ‘This is too good to be true. This doesn’t smell right.’ ” He added, “There’s probably some false positives in there as well, but, in general, I think we’re a pretty good gauge of public sentiment. When we’re talking about a faith-based collapse, you’re going to start to see the chips in the foundation on social media first.”
Even with adequate shelter and with limited physical activity, losing access to water means certain death after a couple of truly rotten days. Thankfully, in the developed world, this is a very uncommon fate: emergencies that leave communities without potable water are not rare, but when they happen, the government practically trips over itself to immediately restore service or to get water trucks on the road.
I would add just a few things though, if you use creamer in your coffee add a few bottles of the powdered version, some dried fruits or a couple large bags of trail mix, pie fillings in a few fruit varieties (awesome in oats!), crackers are great for kids who won’t eat a tuna, spam or other canned meat sandwich but they may be willing to eat “lunchables” DIY of course!, and other all in one items like spaghetti O’s, canned stew, canned ravioli, and ramen. It may not be the healthiest solutions but if you need these items you will be exceptionally grateful you have them!
Fletch runs the YouTube channel OzarksTactical Homesteading, the description of which reads, “Liberty-minded, faith-based, pro-Second Amendment, pro–home school.” He posts videos on prepping and reviews tactical gear from his property somewhere in northwest Arkansas. Occasionally, Fletch records rants in the car. The mainstream media and Walmart door greeters—the “door gestapo”—are recent targets of his iPhone manifesto. He’s gained more than 5,000 subscribers since launching the channel in 2011. 
Your run-of-the-mill shoe stank might not pose much of a survival threat, but trench foot certainly will; baking soda is great at absorbing the moisture that might otherwise literally cause your feet to rot off your legs. As for the health of your teeth -- it will be pretty hard to get through your day's rations of homemade jerky and hardtack without some high-quality chompers. And you certainly don't want to rely on that pesky fluoride that will "kill your brain over time" (um, what?).
thank you for this, it gives me more ideas on what to look at, being married to a filipina we eat lots of rice, we are a family of 5, with younger children. We have enough food for 2yrs put away. but with this list in hand we will put more away.we look at long term, as u do not know what is really going to happen at any given time. while i am still alive i will make sure my family is taken care off and protected..only thing we dont have is a farm and that would be the bee’s knees…lots of people in here give great feed back and some bloody good idea…thank u everyone…for the wonderful comments, the advice never got astray..
Above all, the nice thing about it is that camping gear doesn't need to just sit in your closet, collecting dust on the off chance that something bad may happen a decade from now. You can simply grab it and head out for the weekend every now and then; camping is fun, doubly so for kids. It's also a great opportunity to test some of your other equipment, and spot potential flaws in your preparedness plans.
Now, there are some dangers to life and limb that we simply can't predict or prevent: the occasional falling piano, the murderous roommate, the untimely stroke. Then there are the risks we take willingly, accepting the inherent and unavoidable trade-offs of our hobbies or jobs: the possibility of being snatched by a giant squid while snorkeling off the coast of California, or the near-certainty of lung fibrosis from toiling in a sugar mine. These are the things we can't or don't want to give up - and that's perfectly fine.
Yishan Wong, an early Facebook employee, was the C.E.O. of Reddit from 2012 to 2014. He, too, had eye surgery for survival purposes, eliminating his dependence, as he put it, “on a nonsustainable external aid for perfect vision.” In an e-mail, Wong told me, “Most people just assume improbable events don’t happen, but technical people tend to view risk very mathematically.” He continued, “The tech preppers do not necessarily think a collapse is likely. They consider it a remote event, but one with a very severe downside, so, given how much money they have, spending a fraction of their net worth to hedge against this . . . is a logical thing to do.”
