I think we should realise that the global food supply has dwindled. The American farmers have had severe droughts and fires. The rice crops in Asia are smaller. Vietnam is not exporting any rice. In the mediterranean countries the harvest was less because the seasonal workers could not migrate due to corona. So preserved goods will also be less. When the going gets tougher, and it will, we will be grateful that we put that extra bag of rice, pasta, tomato paste, baked beans, pickles, salt, oil, vinegar, mixed herbs, spices, sardines and sausages, a packet of soup, flour, sugar, some booze, tobacco, candles, matches or a lighter, soap and shampoo when we shopped the last few times. And of course, always keep a full pack of toilet paper in reserve. I think our days of full supermarket shelves are over. Don't forget baking powder, yeast, stock cubes, curry powder and bisto. Please shop wisely. Adding ONE extra bag or a can of something at a time is not being irresponsible and selfish, rather is is being wise in this unsettled world. And we CAN find a space to store it, like under the couch, in the wardrobe, under the bed.
