Agreed, what happens on the other side of the gate in supply chain, food processing, etc., is not something we can influence but that is for someone else to tackle.
Yes we can. We can work with our allies in the environmental and social justice movement to bring about the necessary changes in the food chain. They can't achieve what they want to see - less pollution, stronger communities, blah blah - without farmers being on board. We can't achieve what we want - a job that pays, presumably - without them being on our side.
All this navel gazing, worrying about what the carbon footprint of your tractor is, it's completely and utterly pointless. No-one will pay you more for your food. Has RT taught the industry nothing ?
