Great Barrier Reef

The Great Barrier Reef in Australia is a favorite destination of scuba divers, underwater explorers, and lovers of exotic, romantic tropical islands. It is a succession of reefs extending from just south of the Tropic of Capricorn off the Queensland coast to Torres Strait in the north.

Great Florida Reef

The only living coral barrier reef in the United States.


  • Recreational boats are used, recreational activities occur in the water, fishing, snorkeling, and scuba diving.


  • Beware of what you step on in the water: even the slightest touch to the coral can damage it.


  • Boat anchors have crushed the coral on impact.


  • A long winter season can decrease the temperature to the point where the coral dies. Higher temperatures can also cause coral bleaching. The rise in sea level is a continuing problem in the Florida Reef.


  • The amount of visitors per year should be monitored and restricted because of the problems that may occur in the reef.
