Regardless of whether you think something catastrophic will happen tomorrow, next month, next year or never, it's a smart plan to have an emergency stash of shelf-stable food and drinking water to last 72 hours per person in your household for whatever natural or manmade disaster.
My grandma's spirit would haunt me from the dead if it found out I only had 72 hours of food in my home.
Food is easy, water is harder
I'm one of those dirty wasteful Italians who buys bottled water, I've always got ~50 litres of water at home, and I live in the dampest part of Italy anyway
I have a few dozen gallons of water stashed in my basement but I also purchased three water filters which I can use to get water out of my lake or any stream. I have Sawyers and Katadins.
This! I don't even live in a disaster prone area, but I always make sure we'd be fine without power/water for a few days at least.
I have plenty of food sitting around, but realistically, 72 hours without food isn't going to be an issue for an non-infant who doesn't have some kind of serious medical conditions. Probably make most people in the US healthier.
I've fasted for over a week for the hell of it, and people have gone much longer. This guy did it for over a year.
Water is a much-less-forgiving resource.
Sure. Most people probably have a bit of fresh food to rely on in the immediate term if disaster hits, but by the time you get to it, you should have a gauge on how long you will need to make that 72 hours supply actually last. Water is also vital but it does take up more space so as a baseline 72 hours of each is a good starting point.
