Vicissitudes by Jason deCaires Taylor - underwater sculpture in Grenada in honor of Africans on the middle passage are moving, beautiful, and help protect marine life.
Oceans teem with microscopic organisms that are constantly drifting down towards the sea bed, living on and attaching to on the way any hard secure surface, such as rock outcrops, and thereby creating the basis of a natural reef. Coral reefs attract an array of marine life such as colorful fish, turtles, sea urchins, crustaceans, sponges, and algae. They also provide enclosed spaces for sea creatures to breed or take refuge.
Only about 10 – 15% of the sea bed has a solid enough substratum to allow reefs to form naturally. In order to increase the number of reefs in these areas artificial reefs have recently been created from materials that are durable, secure and environmentally sensitive. These reefs appear to have been successful in that they have attracted coral growth which, in turn, can support an entire marine ecosystem.
One of the greatest benefits of artificial reefs is that they have lifted the pressure off natural reefs which, over the past few decades, have been over-fished and over-visited. By diverting attention to artificial reefs, natural reefs have now been given a greater chance to repair and to regenerate.
