Experts warn all coral reefs could be extinct by 2050

February 24, 2011 BAHAMAS – The world’s coral reefs could be wiped out by 2050 unless action is taken to stop threats posed to the “rainforests of the sea”. Warmer seas caused by global warming; ocean acidification blamed on carbon dioxide pollution; shipping, overfishing, coastal development and agricultural runoff all pose a threat to coral reefs, which hundreds of millions of people depend on for a living, says the report. “If left unchecked, more than 90 per cent of reefs will be threatened by 2030 and nearly all reefs will be at risk by 2050,” says the “Reefs at Risk Revisited” report, which was compiled by dozens of research, conservation and educational groups led by the World Resources Institute think-tank. “Local pressures” on reefs, including overfishing, coastal development and pollution, pose the most immediate and direct threats to the world’s reefs, threatening more than 60 per cent of the colorful sea “forests” in the short term, the report says. The impacts of climate change – a “global threat” to reefs – is compounding the local pressures. “Warming seas have already caused widespread damage to reefs, with high temperatures driving a stress response called coral bleaching, where corals lose their colorful symbiotic algae, exposing their white skeletons,” the report says. –Herald Sun
