LADY ELLIOT ISLAND, Australia
Wider Image - Great Barrier Reef At Risk
A tourist snorkels in the lagoon located on Lady Elliot Island, north-east of the town of Bundaberg in Queensland, Australia, June 9, 2015. The lagoon, which is occupied by turtles during high tide, is only accessible for snorkelling during this time. UNESCO World Heritage delegates recently snorkelled on Australia’s Great Barrier Reef, thousands of coral reefs, which stretch over 2,000 km off the northeast coast. Surrounded by manta rays, dolphins and reef sharks, their mission was to check the health of the world's largest living ecosystem, which brings in billions of dollars a year in tourism. Some coral has been badly damaged and animal species, including dugong and large green turtles, are threatened. UNESCO will say on Wednesday whether it will place the reef on a list of endangered World Heritage sites, a move the Australian government wants to avoid at all costs, having lobbied hard overseas. Earlier this year, UNESCO said the reef's outlook was "poor". REUTERS/David Gray
