1 00:00:04,037 --> 00:00:09,342 In the spring of 2008, an 84 foot pleasure boat departed from Fort 2 00:00:09,442 --> 00:00:12,679 Lauderdale bound for the Caribbean. 3 00:00:12,779 --> 00:00:14,981 Thirty miles south of Miami it strayed from 4 00:00:15,081 --> 00:00:20,787 marked navigation channels into the shallow waters of Biscayne National Park. 5 00:00:20,887 --> 00:00:26,526 Suddenly, running at full speed, it collided with a coral reef near Elliott Key. 6 00:00:26,626 --> 00:00:32,966 Corals, sponges and sea fans were instantly obliterated as the boats twin 7 00:00:33,066 --> 00:00:39,439 propellers plowed through the reef. The engines were disabled and the powerless 8 00:00:39,539 --> 00:00:46,746 vessel drifted in the wind until rounding on a second reef. Here, the wind 9 00:00:46,846 --> 00:00:51,684 and waves rocked the boat on its hull, shattering the ancient coral mounds and 10 00:00:51,785 --> 00:01:00,527 pounding the reef into rubble. A coral reef that had taken centuries to grow 11 00:01:00,627 --> 00:01:11,604 was destroyed in just moments. Two and a half years later, coral researchers and 12 00:01:11,704 --> 00:01:16,643 resource managers are searching for solutions to help the oceans declining 13 00:01:16,743 --> 00:01:23,650 coral reefs. Can new technologies and naturally occurring biological 14 00:01:23,750 --> 00:01:27,787 mechanisms help restore lost coral communities. 15 00:01:27,887 --> 00:01:31,887 And can ecological balance be returned to Florida's coral reefs?
