Sharks are vital to the economies of many islands in Micronesia primarily because many islands have limited fertile land or mineral resources and must depend on the ocean. Sharks play a crucial role in maintaining the health of marine ecosystems, which in turn supports fisheries that island communities rely on for food and income. Healthy shark populations help to regulate the populations of other fish species, ensuring a balanced ecosystem that can sustain fishing industries.
Moreover, the tourism industry is also a significant aspect, as many visitors are attracted to the unique marine life, including sharks. Ecotourism activities such as shark diving can generate substantial revenue for these islands. Therefore, the presence of sharks not only contributes to the ecological balance but also boosts the tourism industry, forming a vital part of the economic framework for many Micronesian islands.
