While Corals Die Along The Great Barrier Reef, Humans Struggle To Adjust

"Nearly a hundred miles off the shore of Port Douglas, Australia, tourists jump into the water of the outer reef. On their dive, they see giant clams, sea turtles and a rainbow of tropical fish, all swimming above brightly colored coral."

"On a boat, marine biologist Lorna Howlett quizzes the tourists in the sunshine. 'How many people out there saw a coral highlighter-yellow?' she asks, eliciting a show of hands. 'What about highlighter-blue? Yeah? Anyone see some hot pinks?'"

"Eager hands shoot up among the few dozen tourists lounging on the deck of the boat in their wetsuits. Everyone's still smiling from their Technicolor tour of the Great Barrier Reef, a UNESCO World Heritage site that encompasses the world's biggest coral reef system and is home to some 400 different types of coral."
