- More than 250,000 crown-of-thorns starfish have been removed from the Great Barrier Reef off Queensland in the past two years, Federal Environment Minister Greg Hunt says. The pest is considered to be one of the biggest threats to the reef and has traditionally been hard to destroy.

Coral reef The Effects Of Coral Bleaching. Coral Bleaching is a process biological in nature and can be difficult to explain in layman’s terms. Coral bleaching has become one of the most recognized topics within the environmental community in the last couple of years. To put it in simple terms, coral bleaching is causes by the healthy coral reef losing its tiny, single-cell algae and usually occurs quite suddenly. Coral bleaching is known to be responsible for killing approximately 18% of the worlds coral reefs. Coral bleaching in most cases is triggered by the introduction of warmer waters than normal to the local eco-system. Be Sure to Check Out Our New Ecotourism Video Section.

Corals The frequency of coral diseases has increased significantly over the last 10 years, causing widespread mortality among reef-building corals. Many scientists believe the increase is related to deteriorating water quality associated with human-made pollutants and increased sea surface temperatures.

- The warmer air and ocean surface temperatures brought on by climate change impact corals and alter coral reef communities by prompting coral bleaching events and altering ocean chemistry. These impacts affect corals and the many organisms that use coral reefs as habitat.

Geography The great barrier reef is located in a sector of the Pacific Ocean off the coast of Australia called the Coral Sea. The Coral Sea is home to the world's largest reef system. The Coral Sea merges with the Tasman Sea in the north and the Pacific Ocean.

- Go far enough from the coast, where the light is low and the waters are deeper, and there's no reef at all. In the Great Barrier Reef, corals set the patterns of life from end to end, says Charlie Veron, coral expert and a longtime chief scientist for the Australian Institute of Marine Science.ot far beneath the surface of the Coral Sea, where the Great Barrier Reef lives, parrotfish teeth grind against rock, crab claws snap as they battle over hiding spots, and a 600-pound grouper pulses its swim bladder to announce its presence with a muscular whump.

Itâs either Adani or the Great Barrier Reef. Are we willing to fight for a wonder of the world? In other words, you’d be naïve to expect any serious action on climate any time soon. That’s why the inconceivable seems now depressingly likely: one of the great wonders of the world slowly dying before our eyes. As goes the reef, so goes the planet. The trajectory that Spaceship Earth’s currently traversing has been carefully plotted – and the course is set on disaster.

How does climate change affect coral reefs? Climate change leads to: 1  A warming ocean: causes thermal stress that contributes to coral bleaching and infectious disease. 2  Sea level rise: causes increases in sedimentation that can lead to the smothering of coral. 3  Changes in storm patterns: leads to stronger and more frequent storms that can cause the destruction of coral reefs. more information...

Great Barrier Reef declared dead in obituary Aerial views of The Great Barrier Reef are seen from above on August 7, 2009 in Cairns, Australia. GREAT BARRIER REEF, Australia A writer has declared the Great Barrier Reef in Australia officially dead after a story in September said that the bleaching of the reef's coral this year has caused it to decline. ABC News in Australia reported last month that bleaching had killed 35 percent of coral in the central and northern parts of the reef.

5 Main Causes of Coral Reef Destruction Coral Reef Destruction due to Water Pollution. Water pollution is perhaps the most obvious cause of coral reef destruction. Reefs are harmed when oil, fertilizer, human and animal waste are dumped in the area. Not only do these elements change the chemical make-up of the water, waste can also block life-giving sunlight to the reef.

- Coral bleaching, if it continues, will threaten coral reefs around the world whenever the weather conditions are unusually hot, and will affect not only reefs that are under stress by human usage but also the most remote and pristine reefs so far untouched by human hands. This is a recipe for disaster for any and all reefs. Growth for a reef occurs slowly. Typically reefs can generate approx one inch of growth per year. Any interruption to this slow growth only weakens the coral and severely limits it’s ability to cope with environmental change..
