A conventional artificial reef uses materials such as concrete, which can be molded into specialized forms (e.g. reef balls). Green artificial reefs incorporate renewable and organic materials such as vegetable fibres and seashells to improve sustainability and reduce energy consumption, pollution, and greenhouse gas emissions.

For back-filling these seven artificial islands, a total area of 13.5 square kilometres (5.2 sq mi), to the height of few meters, China had to destroy surrounding reefs and pump 40 to 50 million m 3 (1.4 to 1.8 billion cu ft) of sand and corals, resulting in significant and irreversible damage to the environment. Frank Muller-Karger, professor ...
The Great Barrier Reef Marine Park Authority (GBRMPA), which is responsible for managing the park, does not consider grey water or exhaust cleaning by-products to be waste under the existing ...
Osborne Reef is an artificial reef off the coast of Fort Lauderdale, Florida at Originally constructed of concrete jacks , it was the subject of an ambitious expansion project utilizing old and discarded tires .
Changes in marine ecosystem dynamics are influenced by socioeconomic activities (for example, fishing, pollution) and human-induced biophysical change (for example, temperature, ocean acidification) and can interact and severely impact marine ecosystem dynamics and the ecosystem services they generate to society. Understanding these direct—or ...
Oyster Reef. Oyster reef restoration refers to the reparation and reconstruction of degraded oyster reefs.Environmental changes, modern fishing practices, [1] over harvesting, [2] water pollution, and other factors, have resulted in damage, disease, and ultimately, a large decline in global population and prevalence of oyster habitats.
The Great Barrier Reef, considered one of the seven natural wonders of the world and a biodiversity hotspot, is located in Australia. Similar to other coral reefs, it is experiencing degradation due to ocean acidification. Ocean acidification results from a rise in atmospheric carbon dioxide, which is taken up by the ocean.
