Take a photographic tour of some of Earth’s most fascinating islands with Duane Silverstein, executive director of Seacology, an NGO that works to protect threatened island ecosystems and cultures around the world. From the beautiful and exotic to the remote and unheard-of, he looks at what makes islands so special, the threats they face, why they must be saved, and how working respectfully with indigenous islanders is crucial. Duane is in conversation with Adam Rutherford, geneticist and the presenter of BBC Radio 4 programme Inside Science and co-presenter of The Curious Cases of Rutherford and Fry.
