Oceans and the Sea

Smugglers, refugees, trade and melting ice and polar exploration are part of the conversation as Rana Mitter is joined in the BBC tent at the Hay Festival by Nobel Prize-winning author Abdulrazak Gurnah, whose books have drawn on his birthplace Zanzibar and the refugees arriving at the Kent coast; climate scientist Professor Emily Shuckburgh, who worked at the British Antarctic Survey; and Joan Passey, author of Cornish Gothic, a New Generation Thinker on the scheme run by BBC Radio 3 and the Arts and Humanities Research Council to turn research into radio.

Producer: Ruth Watts

You can find a series of Lunchtime concerts recorded with audiences at Hay being broadcast on BBC Radio 3 and an episode of The Verb with Ian McMillan. The Free Thinking website has a collection of episodes exploring Green Thinking and the environment - and a programmes looking at the history of the sea with artist Hew Locke and three historians.
