The battle for the soul of the organic movement

When Lawrence Woodward started out in organic farming he was a self-described "naive, drop-out", with a simple interest in how people eat. He did a farming course and learned to drive a tractor. He learned the hard way how to turn a conventional farm "organic."

Thirty years on, he has seen organic farming transform from a cottage industry into a billion dollar game played by international food companies. And it's not just about chickens, carrots and lentils. Consumers hoping to eat healthier can also salve their social conscience with organic wine, mouthwash, surfboards, paint, jeans, pram blankets -- the list is endless.
