Artificial reefs are man-made structures placed in oceans or large bodies of water to promote marine life. They can be made from various materials, such as concrete, steel, or even sunken ships. These structures provide habitats for fish and other marine organisms, helping to enhance biodiversity and support local fisheries. The primary purpose of artificial reefs is to create a safe environment for marine species to thrive. They can also attract recreational activities like scuba diving and fishing, benefiting local economies. By mimicking natural reefs, artificial reefs play a crucial role in marine conservation efforts.
