No eco-hero needed, Hilarysmum - just a couple of people who are willing to co-operate.
Say, 3-4 people who live in the same area, producing different items. Say, pork, potatoes, fresh veg. fruit, and/or food products made from a selection of said products. If these people drew up an agreement (doesn't have to be hugely complicated, just the terms of the arrangement, witnessed, to safeguard everyones interests ) to sell one anothers products at a market (or 2, depending on the area), then that would cut down the transportation cost and workload for all of them... Ok, i wouldn't work for all of us, but there are bound to be some people on this forum who could make it work!!
I can't think of any reason why a thread couldn't be started asking for names , locations, and produce available for anyone interested.
From that, it has to be possible to work out who can produce what, and ideas on where to sell - whether markets, car boot sales, or whatever.
I've had lots of people express interest in pork as soon as they heard I had pigs, especially bacon "like it used to taste".
I can't see why things would be different anywhere else?? People just don't know where to buy decent food - my solution is to produce my own, but remember the biggest companies all started small.............. (Then they got greedy, which I hope wouldn't happen in this case)
It seems to me to be the only way of fighting back.
