Underwater art installations are creative works placed beneath the surface of oceans, lakes, or rivers. These installations can include sculptures, murals, and other artistic expressions designed to be viewed while diving or snorkeling. They often aim to raise awareness about marine conservation and the importance of protecting aquatic ecosystems. Many underwater art installations are made from eco-friendly materials to minimize environmental impact. Notable examples include the Museo Subacuático de Arte in Cancún, Mexico, which features over 500 submerged sculptures. These installations not only enhance the beauty of underwater environments but also provide habitats for marine life.
