REEF BALLS
Andre Rodrigues of Key Largo, Fla., left, and Tom Lardner of Islamorada, Fla., both students at Coral Shore High School in the Florida Keys, install one of several reef balls Thursday, May 25, 2000, off Islamorada. The reef balls, sunk in the Florida Keys National Marine Sanctuary, serve as foundation for coral growth to attract fish and other marine life. Students built the reef balls, installed them and will monitor their ability to serve as marine habitats. (AP Photo/Bob Care, ho)
