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.
In the next decade Howard Ruff warned about socio-economic collapse in his 1974 book Famine and Survival in America. Ruff's book was published during a period of rampant inflation in the wake of the 1973 oil crisis. Most of the elements of survivalism can be found there, including advice on food storage. The book championed the claim that precious metals, such as gold and silver, have an intrinsic worth that makes them more usable in the event of a socioeconomic collapse than fiat currency. Ruff later published milder variations of the same themes, such as How to Prosper During the Coming Bad Years, a best-seller in 1979.
