3. Fisheries Powerhouse: Sustaining Global Food Security

Though they occupy less than 1% of the ocean floor, coral reefs support an estimated 25% of all marine life and are therefore essential to the worldwide fishing sector. Many of the many fish species found in these varied ecosystems are commercially valuable; they also act as nurseries and homes. With millions of people depending on reef-associated fisheries for their livelihoods and food security globally, these resources have enormous economic worth. Often the foundation of local economies in developing nations, coral reef fisheries give coastal towns both revenue and food. Reef fish for food and the aquarium business bring in billions of dollars a year worldwide. Furthermore adding another layer of economic worth is the potential for novel medications and goods derived from the genetic variety seen in coral reef ecosystems. Long-term financial gains depend on sustainable management of coral reef fisheries since overfishing can cause an ecosystem collapse and financial losses. In addition to maintaining the natural equilibrium, initiatives to apply sustainable fishing methods and marine protected areas guarantee the ongoing economic survival of reef-dependent societies.
