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.
“I’m actually responsible, indirectly, for the end of the meetups,” Dr. Shealy tells me inside his Springfield clinic off Chestnut Expressway, and not just because he thinks the earth is more than 6,000 years old. (Andrew: says you can’t trust anyone who believes that.) He sports a red crewneck, navy blue sweatpants, a stretchy metal watch and rectangular glasses. The 85-year-old—he’s more energetic than most people half his age—specializes in holistic medicine; the first thing he asks me is my birthday, and do I know what my astrological sign means. On my way out, he asks if he can hug me, and when I oblige, a toothy grin pulls wide the spritely doctor’s cheeks. “I believe it’s an important part of human contact,” he says.
In both his book Rawles on Retreats and Relocation and in his survivalist novel, Patriots: A Novel of Survival in the Coming Collapse, Rawles describes in great detail retreat groups "upgrading" brick or other masonry houses with steel reinforced window shutters and doors, excavating anti-vehicular ditches, installing warded gate locks, constructing concertina wire obstacles and fougasses, and setting up listening post/observation posts (LP/OPs.) Rawles is a proponent of including a mantrap foyer at survival retreats, an architectural element that he calls a "crushroom".
What’s a bivvy? Glad you asked. The modern term refers to a weatherproof bag that is used in the wilderness or in an emergency setting to provide shelter (typically for one person, like a sleeping bag). We get the word from the UK (where they spell it with two “V”s), and it’s based on the more familiar word bivouac (meaning a temporary encampment). A bivy can be used in conjunction with a sleeping bag, to create a more weather resistant shell, or a heat reflecting liner. Or the bag can be used as a standalone shelter. Items like these have been on the market for years, but as materials improve – their weight keeps dropping and their effectiveness is increasing. Enter the TACT Bivvy Emergency Sleeping Bag from Survival Frog. This tight-packing bivy is made from our HeatEcho™ thermal reflective material to hold in your precious body heat. Like a space blanket, these remarkable materials can reflect back as much as 90% of your body heat. The bag is also windproof, waterproof and reinforced with taped seams. These are a great survival resource for your vehicle (particularly in the winter), but they’re a great fit in your survival kit or bug out bag too. Each one packs down small into nylon stuff sack provided, and they weigh less than 5 ounces each. There is a bright orange version, perfect for assisting SAR crews in finding you. You can also get a green version, for a lower profile in the wild. Either way, it’s a feather-weight shelter that fits in the palm of your hand!
