That is a massive worry for you Windy. I hope you can get some help soon. I think our farmers, large and small, are up against it this year.
From what I have seen at the shop I work at, the rationing of sunflower oil purchases by supermarkets is almost 100% driven by panic buying and hoarding. We had people coming in with shopping trolleys wanting the clear the shelves of everything we had, so the signs went up and they are allowed 1 bottle each.
Lockdown taught the supermarkets a lot and the main lesson was to nip hoarding in the bud. Once the supply chain is broken, it can take weeks for stock to come through and that means lots of other people going without.
There is a global problem looming over food security, fertilisers and farming and it not going to be easy anyone, especially poor nations. We might not be able to do much as consumers about the root causes, but we do need to remember some of those war values. Don’t be greedy, waste nothing, value everything that our farmers and our plots produce. About 1/3 of what the world produces annually is wasted. That needs to stop and we can all help with that.
