I would like to know why you think farm-to-table is inherently unsustainable? Many farmers in the Highlands of Scotland make a good living selling superior beef to restaurants and butchers in the UK. They do this without regular factory farming methods. Is it less efficient compared to clearing thousands of acres in order to grow a single product which is fed government subsidised corn? Pound for pound, absolutely. Which is why some people decide to eat meat less regularly, but eat the best when they do.
