Sharks are one of the great icons of wildlife and the oceanic wilderness and yet are in severe decline across the world. How can people and sharks share the oceans?

Sharks are in decline across the world's oceans. It can be argued sharks have an image problem with reports of attacks on swimmers and surfers. Persecution and deliberate killing to clear areas near swimming beaches are only a contributor to shark decline. Legal fishing, by-catch, catching sharks for their fins are large contributors to shark decline. In this programme Monty Don talks to a wildlife cameraman who has filmed sharks for 20 years and recorded his observations of shark decline in his dive logs. In the Shared Planet studio we have Kelvin Boot and invited guests to talk about the ways in which the experts believe we can share the oceans with the large diverse group of fish. And a report from Fiji where a single living shark is allegedly worth $50,000 a year in dive tourist revenue.
