We all know that the majority of shark species are in decline. But what actually happens if they are lost from the ecosystem? How important are sharks? We pitch these questions to scientist, shark enthusiast and author Dr David Shiffman, who spends a lot of his time highlighting why sharks really do matter – not just in an ecological sense, but also from a social, economic and cultural perspective. We talk to David about the ecological role of sharks, sustainability, the dangers of spreading misinformation, and David's brand new book 'Why Sharks Matter'. And, of course, the most important question of all: sharks or dinosaurs?!
