Great Barrier Reef. Sitting off the east coast of Australia, the Great Barrier Reef is the worldâs largest coral reef system, covering more than 344 000 sq km. The reefâs diversity of life faces numerous threats such as climate change, pollution, fishing and outbreaks of the coral-preying crown-of-thorns starfish.
Coral reefs: tropical corals. Australia's 2,000km-long Great Barrier Reef is the worldâs largest coral reef. Tropical coral reefs are found between 30Â° north and south of the equator, in areas where surface water temperatures do not drop below 16Â°C. The total area of the world's tropical coral reefs is around 284,300km2. Tropical reefs can grow upwards at rates of 1cm to 100cm per year. They can form huge structures over incredibly long periods of time, making them the largest and oldest living systems on earth.
