Up to 93% of corals have been smothered by the sediment brought by the $205 million Deep Dredge project at Port Miami.
New research shows that suspended sediment accumulated via human activities can impair the breathing of fish, such as clownfish, as well as increases the rate of disease in fish.
The iconic Great Barrier Reef in Australia avoided being put on the World Heritage Site's "in danger" list, based on a UNESCO draft report, however concerns were still raised about its future in the long term.
Just after recent research warned that the world's most iconic ecosystems, including the Great Barrier Reef, may collapse under climate change, a new study is saying that this iconic site can in fact be saved.
Last September, conservationists were thrilled to see the Australian government rescind its plans to dump sediment from dredging into Great Barrier Reef waters. Now however, it has been revealed that four more dredging projects near the reef are still likely to occur, and sediment from these digs could still be dumped within the greater World Heritage Area.
