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.

Scuba diving tourism is a growth industry, and it is necessary to consider environmental sustainability, as the expanding impact of divers can adversely affect the marine environment in several ways, and the impact also depends on the specific environment. Tropical coral reefs are more easily damaged by poor diving skills than some temperate ...
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 ...
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 ...
A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water. [55] Many reefs result from natural, abiotic processes but there are also reefs such as the coral reefs of tropical waters formed by biotic processes dominated by corals and coralline algae.
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 .
Marine pollution made further international headlines after the 1967 crash of the oil tanker Torrey Canyon, and after the 1969 Santa Barbara oil spill off the coast of California. [citation needed] Marine pollution was a major area of discussion during the 1972 United Nations Conference on the Human Environment, held in Stockholm.
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.
