Though thrown into the spotlight by the anniversary of the film Jaws, cage diving has in fact been available as a tourist attraction for the last three or four years. The practice began, and still mainly takes place, in a 60-mile stretch of ocean south of Cape Town known as Shark Alley. The subject of some controversy, it remains to be seen whether cage diving will be an enduring tourist attraction. The practice is already banned in California, and is the subject of major debate in South Africa, where marine environmentalists and tour operators are locked in a fierce argument about whether it is to blame for an increased number of shark attacks. Those opposed to cage diving argue that it increases the possibility of sharks forming an association between humans and food. After almost two decades with virtually no attacks, five (two fatal) have been reported in South Africa this year.
