Half of Great Barrier Reef has vanished, study finds http://apocadocs.com/s.pl?1349184333
Australia's Great Barrier Reef is a glittering gem -- the world's largest coral reef ecosystem -- chock-full of diverse marine life. But new research shows it is also in steep decline, with half of the reef vanishing in the past 27 years.
Katharina Fabricius, a coral reef ecologist at the Australian Institute of Marine Science and study co-author, told LiveScience that she has been diving and working on the reef since 1988 -- and has watched the decline. "I hear of the changes anecdotally, but this is the first long-term look at the overall status of the reef. There are still a lot of fish, and you can see giant clams, but not the same color and diversity as in the past."...
The biggest factors are smashing from tropical cyclones, crown-of-thorns starfish that eat coral and are boosted by nutrient runoff from agriculture, and coral bleaching from high-temperatures, which are rising due to climate change.
