Ros Burgin combines her love of sculpture with a compulsion to express her feelings about environmental causes. In this episode, she talks about how a previous career on sailing ships first gave her a direct experience of pollution and climate change, how sculpture for her is object and material based, how water emerged as a key area of her practice, the types of found materials she uses, the ingenuity behind recontextualising them, how female equality is another concern and how a recent trip to the Arctic icecap has inspired a future series of works.
