Viral pathogens most often found in water are typically Hepatitis A, Norwalk and Rotovirus, all of which are smaller than most filters are incapable of trapping. They’re species specific which means human to human transmission, and all 3 are associated most often with fecal contamination, thus the further you get from population centers, the lower the risk becomes. For viral coverage, water purification is needed to kill the virus. Chlorine base chemicals are the best treatment next to boiling. UV pens and filter add-ons work good, but are not as effective as heat/chemical treatment. If you know the area you’re heading to, has a previous reputation of human traffic (like campgrounds), then avoid the UV treatment. If the area you’re in is not a high traffic area, UV is alright for use, but personally, I’d rather heat or chemically treat to be sure, and just bypass the expense and extra weight of a UV purifier.
Disaster preparedness doesn't need to be complicated, but you’ll find that shopping and collecting gear for a DIY bug out bag can prove to be difficult. In many cases, the DIY approach may prove more expensive than necessary, leaving you with items you don’t really need—and shouldn’t waste your money on. Instead of forcing useless items into a bag that won’t hold up, opt for a pre-packed, top-rated bug out bag. 
I think that The Long Dark is the best survival game ever. It's not only the great mechanics and survival elements that make the game great, but atmosphere plays a big role, too. It makes you feel like you are really there. Also, while the devs state that the game doesn't teach how to survive, the medicinal plants are actually real and their proprieties, too. See More
Before we get started, if you just want a list of everything you need to have on hand to be ready for a disaster or emergency situation, here’s our full list of essential emergency supplies to survive any disaster. If you’ve acquired everything on that list, it’s fair to say that you’re officially a prepper, and that you’re ready for most survival scenarios.
There is a delicate balance between exploring and surviving, and every aspect of gameplay is closely related. The amount of activity the player performs and the distance they can travel and explore, are balanced around certain metrics such as time, warmth, and calories - and all of these game systems are closely related resulting in a finely tuned experience. For example, eating food replenishes calories, but in order to find food, you have to explore and salvage which causes you to burn calories in the first place. The player must watch how many calories they burn, even when sleeping, and make sure they find or hunt enough food to keep themselves going. On top of this, the player needs to seek shelter from the cold, make sure they are wearing the appropriate clothing, and build fires to stay warm and cook food. During your explorations to salvage supplies and look for food items, you will need to explore carefully as to not get stuck without a place to sleep for the night. See More
This game is the realistic version of Minecraft. Game customization allows you to play the game in Creative mode up to Realisticly Hard with running zombies. You can play with only walking zombies if you want. The game relies on one player being the Host and it autosaves. Unlike Minecraft, it offers skills that you can level up as well as points you can use to speed up skills. I recommend playing this with a friend. Survival is not fun alone. See More
sorry Paul…if you get a Lifesaver bottle, it does filter bacteria…in fact it filters everything. And its good for 1000s of litres. http://www.iconlifesaver.eu/ Theres lots in the article I agree with, and lots I don’t. Get an SAS style hammock with shelter for over top and at least be comfortable. An ultra light sleeping bag weights less that 12 ozs and is a whole lot more comfortable than an emergency blanket. There are so many LED lights out there that you can pack a small crank or solar rechargeable light. Fire might bring the baddies. Better to be safe and unseen than seen an unsafe.
Design – The best bug out bag is one with plenty of pockets. This allows you to compartmentalize your bug out bag essentials so that you know exactly where everything is and you don’t have to dig through mountains of other stuff to find what you need. Put all your fire and light things together such as tactical flashlight, candles, headlamp, fire starting kit and storm proof matches. Put maps, GPS devices, compass and other navigation related items in their own pocket and so on. The more you can separate things the easier it will be to transcend your difficulties.

There are many choices of packs out there that would make a good Bug Out Bag. In the end, the important thing to keep in mind is your personal preference. Bigger doesn’t always mean better when it comes to selecting the right bug out bag. Remember that a Bug Out Bag is recommended to store 3 days worth of rations, water, and gear in a survival situation.
You don’t need a huge space to store emergency supplies if you plan wisely. Use every inch of your storage space for efficiency and necessity. When buying emergency supplies, look for stackable items with minimal packaging or that serve multiple purposes (multi-function items are great because you get the benefits of multiple tools without using up all that storage space). For example, MREs don’t take as much space as individual ingredients. Buying freeze-dried food instead of ready-to-eat foods lets you store even more in a smaller area.

Once you’ve gotten some idea of what you need to do and how to do it, you really need to sit down and make an overall plan. This is kind of like making an outline for a book or story. This is where you’ll list any plans you have or things you still need to do in general terms. You should be continually updating this overall emergency plan. It should be in one place (or exact copies) that anyone in the family will know where it is to grab. I’d keep it in a binder at the house and some kind of copy in your bug out bag. Digital backups are always a good idea but don’t make it your only method.
SHTF is an acronym that stands for sh*t hits the fan. This means that something drastic has happened, like a natural disaster, financial crisis, or a war has started. This term is generally used for when things go south quickly. The other acronym that is commonly used to signal it is time to pull out your bug out bag is ‘TEOTWAWKI’. This stands for ‘the end of the world as we know it’.
There are a number of emergency food storage methods that are worth learning about to extend the shelf life of typical stockpile foods. These methods sometimes require modern equipment which you may not want to get your hands on – if that’s the case, you can instead read up on primitive food storage methods, which would include skills like fermentation and smoking/curing meat.
More importantly, though, the way you survive in Minecraft is entirely up to you. You could build an elaborate fortress and play a defence-style game, fending off the creatures of the night. Or you could craft exciting weaponry and venture out into the most dangerous zones of the world, testing both your mettle and metal. The world is literally endless and filled with amazing natural wonders just begging to be explored. Just remember to eat something every now and again, and you’ll be fine.
