Theodora Eleni talks to Emma Silverthorn about her book which tells the story of how her grandparents, Anna and Peter Roberts, changed the way in which we farm today by founding what is now the world’s largest and most successful animal welfare charity.

Together they discuss how Anna and Peter’s campaign changed how corporate giants such as McDonalds and others changed the way in which they produced their meat and how their campaign influenced the Royal Family to change the way they consumed livestock products by changing to free range produce.
