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.

Plastic pollution in the ocean is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean.
Even though freshwater pollution is the major contributor to marine plastic pollution there is little studies done and data collection for the amount of pollution going from freshwater to marine. Majority of papers conclude that there is minimal data collection of plastic debris in freshwater environments and natural terrestrial environments ...
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.
Coral reefs provide a vital part of the ocean ecosystem, serving as the habitat to many species and protection for the coastline from erosion and storms. [6] At this time, thirty to fifty percent of Earth's coral reefs have already been lost . Coral has been threatened by pollution, overfishing, and unsafe fishing techniques. [7]
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.
Debris on beach near Dar es Salaam, Tanzania Debris collected from beaches on Tern Island in the French Frigate Shoals over one month. Researchers classify debris as either land- or ocean-based; in 1991, the United Nations Joint Group of Experts on the Scientific Aspects of Marine Pollution estimated that up to 80% of the pollution was land-based, [5] with the remaining 20% originating from ...
