We're all for rethinking our relationship to food: from food culture guru Michael Pollan to Ballarat woodsman Rohan Anderson, some great people are trying to help us work out how best to eat. 

Briton Pam Warhurst is throwing her hat into the ring. In this TED Talk she shows how her tiny town of Todmorden, England (population 15,000) has started using its unclaimed public space to grow vegetables for folks to eat in a project called Incredible Edible. It's a simple idea, well-put, but with vast acres of grass stretching uselessly across our suburbs, one that supermarket-dependent Australia could do well to watch.
