Marine resources are resources (physical and biological entities) that are found in oceans and are useful for humans. The term was popularized through Sustainable Development Goal 14 which is about "Life below water" and is one of the 17 Sustainable Development Goals established by the United Nations in 2015. The official wording of the goal is to "Conserve and sustainably use the oceans, seas and marine resources for sustainable development".

👉 Marine resources in the context of Marine protected area
A marine protected area (MPA) is a protected area of the world's seas, oceans, estuaries or in the US, the Great Lakes. These marine areas can come in many forms ranging from wildlife refuges to research facilities. MPAs restrict human activity for a conservation purpose, typically to protect natural or cultural resources. Such marine resources are protected by local, state, territorial, native, regional, national, or international authorities and differ substantially among and between nations. This variation includes different limitations on development, fishing practices, fishing seasons and catch limits, moorings and bans on removing or disrupting marine life. MPAs can provide economic benefits by supporting the fishing industry through the revival of fish stocks, as well as job creation and other market benefits via ecotourism. MPAs can provide value to mobile species.
There are a number of global examples of large marine conservation areas. The Papahānaumokuākea Marine National Monument, is situated in the central Pacific Ocean, around Hawaii, occupying an area of 1.5 million square kilometers. The area is rich in wild life, including the green turtle and the Hawaiian monkfish, alongside 7,000 other species, and 14 million seabirds. In 2017 the Cook Islands passed the Marae Moana Act designating the whole of the country's marine exclusive economic zone, which has an area of 1.9 million square kilometers as a zone with the purpose of protecting and conserving the "ecological, biodiversity and heritage values of the Cook Islands marine environment". Other large marine conservation areas include those around Antarctica, New Caledonia, Greenland, Alaska, Ascension Island, and Brazil.

Marine resources in the context of Ocean conservation
Marine conservation, also known as ocean conservation, is the protection and preservation of ecosystems in oceans and seas through planned management in order to prevent the over-exploitation of these marine resources. Marine conservation is informed by the study of marine plants and animal resources and ecosystem functions and is driven by response to the manifested negative effects seen in the environment such as species loss, habitat degradation and changes in ecosystem functions and focuses on limiting human-caused damage to marine ecosystems, restoring damaged marine ecosystems, and preserving vulnerable species and ecosystems of the marine life. Marine conservation is a relatively new discipline which has developed as a response to biological issues such as extinction and marine habitats change.
Marine conservationists rely on a combination of scientific principles derived from marine biology, Ecology, oceanography, and fisheries science, as well as on human factors, such as demand for marine resources, maritime law, economics, and policy, in order to determine how to best protect and conserve marine species and ecosystems. Marine conservation may be described as a sub-discipline of conservation biology.
