I think it’s more of a new way of thinking, a rebalance of our previously piss-poor reactions to normal occurrences. By ‘our’ I mean the government, but also general understanding and preparedness.
We’re so worried about looking reactionary, OTT or like conspiracy theorists or American preppers, that we’re doing ourselves a disservice. It’s not about nuclear war, tins won’t help anyone! It’s more to do with power/energy restrictions, storms, cyber attacks and trade route instability.
We’re so used to being able to get literally anything at any time, I just got Amazon to bring me ibuprofen in 30 mins the other night as I was tired and my son was unwell. If your local Tesco metro has had no deliveries for whatever reason, and it’s because of some cyber attack on I don’t know, say whatever they use to manage stock, and it’s across the board so you can’t use Amazon either and people have cleaned out the local pharmacy…. How are you getting ibuprofen? There was a shortage not that long ago of amoxicillin when my child needed it, I had to drive miles to a pharmacy to get it after ringing round about 10 different ones locally. Antibiotics you can’t buy to store anyway, but again this is a part of the concern. You soon feel it, when something you’ve taken for granted as always being available is suddenly not.
I don’t think having some water supplies, a few tins and some dried goods is irrational at all, it makes sense! Just buy things you like and would eat anyway, and eat/replace every few months to stop it going off. If it’s never needed then wonderful! I’m sure most people in war zones or left high and dry never thought it would be them, either! What’s the harm in being prepared? It doesn’t make someone a credulous victim of scaremongering, most countries are way more careful than we are on this subject and people keep a small cupboard just for this purpose.
My friend in Italy showed me their pantry as they were using some stuff out of it to be replaced so it wouldn’t get old. She said everyone in the neighbourhood did this in case of power cuts or supply chain issues. Perfectly stocked pantry with additionally packs of silver blankets, candles, batteries, massive water bottles. This was right by the pantry they use every day. Once in a while they replace the old stock and bring it all forward. There’s no gross tins from 1997, they check it once in a while and rotate. Never goes to waste, so what’s the issue?
