Trips for tourists to sharks can cause tragedy on the South African coast. The fact that tourists see the great white sharks by the underwater cage has become very fashionable in recent years and this type of shows have become a great business for anyone who has boat and dive equipment.

However, biologists warn that sharks are learning to relate food and humans, as in recent years the number of attacks has increased. In addition to the risk posed by these shows for tourists, it has been discovered that some drivers use surfboards or children's toys to attract sharks, which means that white sharks will learn to attack humans. Cases of this type have occurred in the Caribbean Sea in recent years.
