Hawaii's coral reefs (e.g. French Frigate Shoals) are a major factor in Hawaii's $800 million a year marine tourism and are being affected negatively by coral bleaching and increased sea surface temperatures, which in turn leads to coral reef diseases. The first large-scale coral bleaching occurred in 1996 and in 2004 it was found that the sea ...
A deadly epidemic that is spreading through the Red Sea has killed off an entire species of sea urchin in the Gulf of Aqaba, imperilling the region's uniquely resilient coral reefs, an Israeli ...
The disappearance of reefs in the past has been attributed to fluctuations – either the sea levels have declined so much that corals were exposed and perished, or the waters rose so much that the corals drowned – Earth's reefs are facing a whole new threat of extinction, on a level unprecedented.
Conservation status for warm-water reef-building corals was analysed for the International Union for Conservation of Nature’s (IUCN) Red List. 44% of warm-water coral species facing extinction ...
The dugong (/ ˈ d (j) uː ɡ ɒ ŋ /; Dugong dugon) is a marine mammal.It is one of four living species of the order Sirenia, which also includes three species of manatees.It is the only living representative of the once-diverse family Dugongidae; its closest modern relative, Steller's sea cow (Hydrodamalis gigas), was hunted to extinction in the 18th century.
The deterioration of coral reefs is mainly linked to human activities – 88% of reefs are threatened through various reasons as listed above, including excessive amounts of CO 2 (carbon dioxide) emissions. Oceans absorb approximately 1/3 of the CO 2 produced by humans, which has detrimental effects on the marine environment.
These threatened species occur in the Great Barrier Reef World Heritage Area [1] and are listed as threatened under the Convention on the Conservation of Migratory Species of Wild Animals (Bonn Convention), CITES (CITES) Agreement, China–Australia Migratory Bird Agreement (CAMBA), Japan–Australia Migratory Bird Agreement or the International Union for the Conservation of Nature Red List ...
