great barrier reef 澳大利亚大堡礁
The Great Barrier Reef is the largest coral reef system in the world composed of over 2,900 individual reefs and 900 islands.The reef is located in the Coral Sea,off the coast of Queensland in northeast Australia.
The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms.This reef structure is composed of and built by billions of tiny organisms,known as coral polyps.The Great Barrier Reef supports a wide diversity of life,and was selected as a World Heritage Site in 1981.CNN has labelled it one of the 7 natural wonders of the world.The Queensland National Trust has named it a state icon of Queensland.
A large part of the reef is protected by the Great Barrier Reef Marine Park,which helps to limit the impact of human use,such as overfishing and tourism.Other environmental pressures to the reef and its ecosystem include water quality from runoff,climate change accompanied by mass coral bleaching,and cyclic outbreaks of the crown-of-thorns starfish.
