Hate to break it to you, but your dog probably has a better chance of making it through a total societal collapse than you do. A quick Internet search of "dog survives" lists everything from drowning to being shot, from bear attacks to war -- whereas the closest you've ever come to "surviving disaster" is getting your wisdom teeth pulled, and even then it was only with the help of a cadre of trained medical professionals and a carton of the strongest painkillers on Earth.
While many outdoor enthusiasts consider the color of a survival kit to be of minor importance, it actually makes good sense to think about this important characteristic. For example, it will be much easier to find your survival kit in an emergency if it is brightly colored or reflective. By contrast, you may find yourself in a situation in which you’ll want to keep a low profile, such as if you are trying to avoid dangerous people. In these cases, you’ll want a black or earth-toned survival kit to help avoid drawing attention to yourself. There are no right or wrong answers in this regard, but you’d be wise to think through the issue carefully before making your choice.
Survival kits, in a variety of sizes, contain supplies and tools to provide a survivor with basic shelter against the elements, help him or her to keep warm, meet basic health and first aid needs, provide food and water, signal to rescuers, and assist in finding the way back to help. Supplies in a survival kit normally contain a knife (often a Swiss army knife or a multi-tool), matches, tinder, first aid kit, bandana, fish hooks, sewing kit, and a flashlight.
People who are not part of survivalist groups or apolitically oriented religious groups also make preparations for emergencies. This can include (depending on the location) preparing for earthquakes, floods, power outages, blizzards, avalanches, wildfires, terrorist attacks, nuclear power plant accidents, hazardous material spills, tornadoes, and hurricanes. These preparations can be as simple as following Red Cross and U.S. Federal Emergency Management Agency (FEMA) recommendations by keeping a first aid kit, shovel, and extra clothes in the car, or by maintaining a small kit of emergency supplies, containing emergency food, water, a space blanket, and other essentials.
Everyone in California is waiting for "The Big One," an earthquake with a magnitude of 8.0 or greater that will destroy infrastructure and cause mass panic. Yet when I moved to the Bay Area from the East Coast, I discovered that since most of the people I knew were making do with small apartments and ever-increasing rent, having supplies on hand for a natural disaster required a space premium that many couldn't afford. I began to put together an earthquake kit that would not only serve my household (which over the years fluctuated from one to three other people) but also my neighborhood, if needed. Even with all that work, I didn't consider myself a prepper, just someone who heeded the Red Cross's warnings.
