Australia’s Great Barrier Reef watchdog gave the green light on Friday for millions of cubic meters of dredged mud to be dumped near the fragile reef to create the world’s biggest coal port and possibly unlock $28 billion in coal projects. The dumping permit clears the way for a major expansion of the port of Abbot Point for two Indian firms and Australian billionaire miner Gina Rinehart, who together have $16 billion worth of coal projects in the untapped, inland Galilee Basin. Environmentalists had fought the plan to dump debris just 25 km from the in danger coral reef.
