Coral reefs throughout the world are dying. Causes of this sad situation are many, pollution, commercial fishing, coastal development and tourism. In some parts of the world it' s too late to save the coral reefs but if the remaining reefs are to survive careful management is needed. In small Pacific islands, where there is little or no tourism and the population continue to live in a traditional way, the coral reefs remain pristine. Australia's grey nurse shark population is on the brink of extinction. It began in the early 60's, fed by the false belief that this shark was a man-eater, and, its own physical makeup - a nasty - looking set of ragged teeth. In the 60's shark-meshing programs began that snared hundreds of local grey nurse. At the same time the new sport of shark hunting targeted these slow moving sharks that schooled in 'shark gutters' off the NSW coast. Ben Cropp is the ideal host who was the most famous of the 60's shark hunters, who then swapped his killer spear for an underwater camera, and began capturing the grey nurse on film instead of a dead trophy. Adventurer Ben Cropp documents the relationship between humans and the Pelican. This beautiful bird is a common sight along the coast of Australia, often appearing on beaches at regular times each day to be fed fish by tourists, or waiting for fishing boats to return and feed them unwanted scraps. Sadly it's this acceptance of humans that causes the plight of the Pelican with injuries from fishing hooks and line and poisoning by pollutants becoming common in some areas.
