Most threatened species on earth: one third of world’s coral reefs on verge of extinction due to ocean pollution, over-fishing

July 10 (Bloomberg) -- A third of the world's corals could be dead within a few years, a shocking new report warns today. The biggest study of its kind has found that 200 out of 700 species of coral are on the brink of extinction - far more than was previously thought. If they die, some of the most beautiful and colourful reefs - home to millions of species of marine life - could be devastated. The speed of decline has shocked the 39 scientists who carried out the survey. Just 10 years ago only 13 species of coral were endangered. Researchers, who published their findings in the journal Science, say they have been badly hit by climate change, coastal development and overfishing.
A team of 39 researchers assessed the state of 704 coral species and found 32.8 percent are threatened with extinction. The study results, published today in the journal Science, are "worse than expected," said co-author Suzanne Livingstone, a marine biologist at Old Dominion University in Norfolk, Virginia. "When we began this process, we didn't think it would be anywhere near as high as that," Livingstone, also a marine species assessor for the International Union for Conservation of Nature, said yesterday in a telephone interview. "Climate change is the overarching threat which comes in on a much larger, global scale," adding to localized disturbances, she said. Death of corals can lead to the collapse of entire ecosystems.
