In the longer term for fresher tasting foods, you will need to consider either growing your own food in a garden and/or obtaining necessary protein through subsistence hunting and fishing. Accordingly, you should properly store an appropriate variety of seeds for your area as well as have on hand fishing equipment and hunting firearms, which can also double for self-defense of your home if necessary.
Size – Everyone overestimates how much they’re carrying when they go backpacking (if everyone who claimed to carry a 100 pound pack actually did we’d have thousands of hiker deaths every year in the US alone). But a survival situation is one time when you need to be cold-light-of-day honest about how much you can carry and what that load should be comprised of to give you the best possible chance of survival. As a general rule you shouldn’t carry more than 15 or 20% of your body weight, which for most people will be between 20 and 40 pounds. With this in mind you’ll want to take into consideration the weight of the pack itself (which must be deducted from the total load) and its volume so that you wind up with a bug out backpack that can carry the appropriate amount of supplies.
Batteries and steel wool. Steel wool is actually a bunch of tiny wires. By rubbing it against a 9v battery, you complete the circuit and the current is enough to burn out the wires. If you are carrying any electronics that require 9v batteries, make sure you bring along steel wool as a tiny addition to your packs. You can use other sizes of batteries but keep in mind that typical ones are only 1.5v so they don’t push nearly the current so you may need several in series for it to work.
Lightweight survival kits are generally seen as a backup means of survival; however, these can kits can be extensive, and have come to include tools that are generally found in larger kits as survival technology advances. Some examples of these tools are high power flashlights, rapid use saws, signal devices such as mini signal mirrors, and water purification methods.
This little dude fits right in your pocket, making it a great everyday carry survival multi-tool. Tungsten carbide blades can hone any blade or sharp edge you need to make, well, sharper, while an emergency whistle and fire starter keep you safe and warm without having to haul out the big guns. You can even sharpen fish hooks with this, which may not seem like a big deal, but you’ll be thankful when the fishmen come for you. Oh yes.
In arctic or alpine areas, survival kits may have additional cold weather clothing (winter hats and gloves), sleeping bags, chemical "hand warmer" packets, sun glasses/snow goggles, snowshoes, a collapsible shovel, a snare wire for small animals, a frying pan, a camp stove, camp stove fuel, a space blanket, matches, a whistle, a compass, tinder, medical equipment, a flint strike, a wire saw, extra socks and a tent designed for arctic use.
Even if you’ve got a good stockpile of food going and you’re cycling as needed to keep your emergency stores edible, that doesn’t mean you’re ready for a true disaster. Having everything stored up and ready at home is great, but what if you’re away from home when a true survival scenario occurs? All your preparation and stockpiling means nothing if you don’t have access to it. That’s why you need to also have a get home bag. A get home bag is exactly what it sounds like – it’s a backpack with some emergency supplies that should be enough to get you home safely in the event of something catastrophic or dangerous happening.
To run all these flashlights, and other things, you’ll need batteries. One of the best ways to go about this is to get all your items to run on the same size battery. That way you only have to stock one size so you can cut down on the number of spares you’ll have to carry. If you can get a solar charger and rechargeable batteries, you’ll be even better off. I use CR123’s for as many things as I can find but there’s a good argument for using AA batteries due to how easy they are to find. I may end up switching over to all rechargeable AA at some point but I’ll have to replace a lot of flashlights to do that. I’ve switched to AA battery lights so I don’t have to carry as many batteries and I can charge them all with the solar panel, USB battery, wall power, or computer USB.

The learned professor assumes that while a long-continued war had strengthened rather than weakened the instinct of paternal devotion, it had also dulled other humanitarian instincts, and raised to the first magnitude the law of the survival of the fittest, with the result that when the exodus took place the strong, the intelligent, and the cunning, together with their offspring, crossed the waters of the Channel or the North Sea to the continent, leaving in unhappy England only the helpless inmates of asylums for the feebleminded and insane.
