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 example, Aspergillus sydowii has been associated with a disease in sea fans, and Serratia marcescens, has been linked to the coral disease white pox. [22] Reefs near human populations can be faced with local stresses, including poor water quality from land-based sources of pollution. [22]
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 ...
Long lines of rope run from the boats, creating an artificial reef that corrals the fish into the net. Once the salmon reach the net, the watchmen sound the alarm, and the crew quickly pulls the ...
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 ...
Sediment pollution from the north Queensland floods washed into the waters of the Great Barrier Reef.In a media release, James Cook University’s TropWater department said the Burdekin River’s ...
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.
