In troubled times like food scarcity because of drought-induced famine or destruction of crops because of pest attacks and plant disease epidemics, the need is felt for adequate food storage measures.
Instead of trying to figure out how to tackle emergencies of a small scale or large scale-ones brought on by national disasters like flood fury, cyclones, tsunamis and others, the wise amongst the people would have taken steps to handle disasters even before they occur. Food Storage measures see to it that enough food is available to feed thousands of poor and affected people during difficult times as they do not have enough resources to fall back on like the rich, who can buy survival kits beforehand and keep them ready for emergency use.
People fall sick or suffer from falls and accidents that leave them incapacitated and unable to cook as they need to rest. Food stored in pantries and freezers have enough of the ready to eat variety of nutritious food, which can be a great blessing at times like these.
So, both for homes and for collective humanity, food storage comes in very handy. Both traditional and modern methods and a combination of these methods help to provide comfort and succor and are thus an absolute necessity.
