People want cheap food. I buy fresh food from supermarkets for a few work social club curries I make and when the farmers market isn't open over Xmas.
My wife, with mine and others help manned a stall at the farmers market for months at peak drought relief last year and raised 12 grand. A bit of effort to not do the easy supermarket thing will support farmers. We've got all our fresh stuff with the above exceptions for 15 plus years. It just tastes better, less food miles, money direct to the farmers.
Still none of that will stop the droughts we face ongoing. But if you can I encourage you to give it a go.
