Long-Term Food Storage is a Practical Concern
Long-term food storage can alleviate the stress of three familiar situations in the modern world. First economic disruption. This circumstance can be mundane, like job loss, but could also include global collapse. Having food on hand buys time for you and your family to maintain their health until you find stability. Furthermore, the skills you gain by learning about food storage and preparation, called human capital, are marketable whether the economy is good or bad.
Second, a food supply lessens the danger of natural disasters. For example, your area may be prone to floods, blizzards, wildfires, or droughts. In all cases, proper long-term food storage will protect you and your loved ones when you are cut off from the rest of your community. This supply is vital whether the roads are impassable for a couple of days or the power is out for weeks on end, as with hurricanes Sandy and Katrina.
Finally, and most appropriate to 2022, having a personal stockpile of properly stored food can help when government mismanagement makes life more challenging. Rampant inflation can make money worthless, and supply-chain disruptions can reduce the availability of products, baby formula or toilet paper, for example.
