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 and 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. Dr Shelley Clarke and Professor Colin Simpfendorfer talk about the ways in which experts believe we can share the oceans with the large diverse group of fish. Plus a report from Fiji where a single living shark is allegedly worth $50,000 a year in dive tourist revenue.
