Pense invites me to imagine a world turned lawless when the ninth transformer blows. Fifteen percent of the New Orleans Police Department deserted during Hurricane Katrina—imagine if the entire force lived where the levees broke. Big box stores killed off regional food distribution centers years ago; all we’ve got is what’s inside Walmart and Sam’s Club, and if you thought Black Friday was bad, imagine the crowds when it’s life or death. Drivers fleeing Springfield will hit roadblocks, where mobs will pull people from their vehicles like the LA rioters did to Reginald Denny. You might commit vehicular manslaughter, the preppers tell me, just to get out alive.
Title and category is misleading, it IS NOT a survival tactics book, but it is a very short (26 pages) story. The story itself isn't great either, sorry; I wrote better "fan fiction" in high school. Please change the type of category it is listed as! Did the document somehow get swapped? Previous reviews discuss learned survival tactics and how it took longer than 10 minutes to read.
Personal Locator Beacons: These are smaller, affordable, reliable, and offer many new features. Companies like SPOT and DeLorme now offer products that post almost real-time tracks of adventurers far off the grid. The SPOT Gen3, for example, sells for as low as $150 and enables users to send simple, pre-programmed messages (all ok, send help, etc.) to friends and family or initiate rescue through a first-responder network.
For global catastrophic risks the costs of food storage become impractical for most of the population  and for some such catastrophes conventional agriculture would not function due to the loss of a large fraction of sunlight (e.g. during nuclear winter or a supervolcano). In such situations, alternative food is necessary, which is converting natural gas and wood fiber to human edible food.
The present disambiguation page holds the title of a primary topic, and an article needs to be written about it. It is believed to qualify as a broad-concept article. It may be written directly at this page or drafted elsewhere and then moved over here. Related titles should be described in Survival, while unrelated titles should be moved to Survival (disambiguation).
