An artificial reef is a human-made structure that is designed to mimic a natural coral reef. Artificial reefs may be created by sinking structures such as ships and oil rigs. Algae and corals attach to the sunken surfaces, forming the artificial reef. These reefs provide habitats for marine life and can also be beneficial in preventing beach erosion. Artificial reefs provide economic benefits by attracting divers and tourists. Some scientists worry that artificial reefs can damage the natural ecosystem if the sites and materials are not chosen carefully and monitored closely.
