Ruminating on Food

Should we be vegetarian? Should we be vegan? Is it wrong, or even unsustainable to eat meat? Students at the London School of Economics seem to think so. Will we see, as some say, the end of farming? Will we return to mixed, organic agriculture or will the whole industry be revolutionised by technology? Are we condemning parts of the world to poverty and hunger while the rest of us over-eat our way to obesity and ill-health? The whole topic of food is full of questions and I don't pretend to have all or any of the answers, but at least I can provide some ideas, issues and opinions.
