This whole discussion was started by JJ who attempted to blame the evils of today on WHITE men who had not matured. Of course, it is immature white men who have abandoned their families. It is immature white men who have dropped out of school and then complain because they can’t get jobs. It is white men who populate the jails and penitentiaries of the country with more of their population than any other race.
Dozens of earthquakes gave Hawaii residences a 48 hour warning before the volcano erupted. The average warning time for California wildfires victims was 20 minutes. Japan’s tsunami victims had a 15-minute warning. Being one of the first to know about oncoming dangers can provide you a head-start. Emergency alert systems are a great preparedness resource. There are several companies that provide emergency alerts services and many of them are free. There are also a couple of different ways to receive alerts. Modern technology has given us many different methods to be notified of possible threats. Here are several options to consider.
I believe the initial goal amount of food stockpile for someone new to prepping should a year. After a year…they should work towards 2 years, etc. I also tend to agree that it’s better to plan for the worst and hope for the best. So for someone new to prepping a years worth of food is a good 1st goal. Will a years worth of food be enough for a downfall scenario you describe? Probably not, but it will be good for a milder SHTF scenario. My advice is for everyone to start stockpiling as much food as they can…just in case.
How many mals can you get from a can of baked beans? You can get 14 servings from a pound of beans. Grains of all types can be cooked like rice hence a pound of grain can give you a weeks worth of meals. Plus you can grind them into flour and make bread or pasta, Beans and whole grain keep almost indefinatly but once ground or cooked (even canned) have alimited shelf life. Just a bit of humble advice.
EVACUATION & LAST SHOPPING TRIP LISTS: I also have evacuation lists (or long term bug-out), including things to do at the house, and things to pack and where they are located (in case we have friends or family helping). We also have lists of things to buy if we have time when SHTF. Hubby’s list includes lumber, fuel, nails, car parts, etc. My list is food products, animal feed etc. We keep cash for the last run. We try to maintain good supplies, but if we can get more at the time, we will.
This group stresses being able to stay alive for indefinite periods in life-threatening wilderness scenarios, including plane crashes, shipwrecks, and being lost in the woods. Concerns are: thirst, hunger, climate, terrain, health, stress, and fear. The rule of 3 is often emphasized as common practice for wilderness survival. The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. 
Anarcho-primitivists share many characteristics with survivalists, most notably predictions of a pending ecological disaster. Writers such as Derrick Jensen argue that industrial civilization is not sustainable, and will therefore inevitably bring about its own collapse. Non-anarchist writers such as Daniel Quinn, Joseph Tainter, and Richard Manning also hold this view. Some members of the Men Going Their Own Way subculture also promote off-grid living and believe that modern society is no longer liveable.
Because I couldn’t stop wondering what it would be like to actually live off the stuff, I placed an order for Wise’s Seven Day Emergency Food and Drink Supply, a shoebox-size assortment of breakfast foods, entrées, and dehydrated whey milk substitute, in addition to a few other options I’d discovered online. I wanted to know what an insurance policy tasted like.
