Few individuals have played such a central role in the modern animal rights movement as Kim Stallwood, whose career stretches back nearly half a century. From working as a holiday job in a slaughter house, to his role as executive director of People for the Ethical Treatment of Animals [PETA], Kim's journey provides a shining example of commitment to the values of truth, justice and compassion. We talk to him about how much has changed, from when a London vegetarian restaurant called Cranks in the 1970s epitomised public perceptions about vegetarianism, to how a plant-based diet has become mainstream, and also what remains to be done to change radically the moral status of animals.
