I think you're right, Patricia, and asking the right question. How do we get justice, health and compassion to the centre of the food system. People, presumably, have been aware for a long time that this is a good idea. But the way food gets to us is overwhelmingly unjust, unhealthy and uncompassionate.

So how to get to a better system? History has an answer. It's one that spreads awareness, yes, but also the possibility of direct change - and that answer is to organise, and be ready to cause trouble to get to this better world. There's a role for writing letters and telling friends and neighbours, but merely the threat of widespread, non-violent, direct action has changed the minds of many governments (and even the odd corporation).
