How did the Aborigines view the Great Barrier Reef?
The animals in the great Barrier reef were part of their DREAM TIME!
How did the great barrier reef become a wonder of the world?
because it had a nice sight of view
Why is the Great Barrier Reef so unique?
The Great Barrier Reef is famous for its rich diversity of marine life, including the colourful coral. The Great Barrier Reef is also famous as it is the largest barrier reef in the world - so large, that it is the only living organism that can be seen from space.
What sort of work do people do at the Great Barrier Reef?
People do not work "at" the Great Barrier Reef, as it is a protected area in the ocean. However, many people work work by conducting tours out into selected areas of the Reef. Some tours are fishing tours; others use glass-bottomed boats to give tourists a clear view of the colours of the reef and the fish; many tours take people out scuba diving and snorkelling in the waters.
Is the Great Barrier Reef endangered?
The Great Barrier Reef does not have an official listing of "endangered". However, it is certainly at risk from various factors, and it is known to be shrinking, but it is unknown by how much. Climate scientists who subscribe to the theory of anthropogenic global warming (i.e. caused by man's activities) predict that the Great Barrier Reef may lose up to 95% of its coral by the middle of the current century. Although the coastline parallel to the Great Barrier Reef has been settled by Europeans for less then 200 years, these scientists believe that the Reef has been shrinking by 20% every 100 years.Climate scientists who subscribe to the theory that global warming is cyclical perhaps have a less drastic view, as they believe that the coral will regenerate, as it has apparently done so in the past. It is a very emotive topic.However, it should be noted that pollution and chemical runoff pose a very real threat to the reef. Mud and chemical runoff tend to limit the sunlight that reaches the coral, causing it to die off. Global warming issues aside, the Great Barrier Reef is most definitely shrinking.It should also be noted that some 40 species which live in and around the Great Barrier Reef are listed as endangered.
Is the Great Barrier Reef the smallest coral reef in the world?
No. At the present moment, the Great Barrier Reef is the world's largest coral reef system. It is, however, shrinking, and it is unknown by how much, or whether this is permanent. Climate scientists who subscribe to the theory of anthropogenic global warming (i.e. caused by man's activities) predict that the Great Barrier Reef may lose up to 95% of its coral by the middle of the current century. Although the coastline parallel to the Great Barrier Reef has been settled by Europeans for less than 200 years, these scientists believe that the Reef has been shrinking by 20% every 100 years. Climate scientists who subscribe to the theory that global warming is cyclical perhaps have a less drastic view, as they believe that the coral will regenerate, as it has apparently done so in the past. There is evidence that the coral goes down much deeper than first thought, and this is an important factor in its regeneration. For this reason, it may well always be the largest barrier reef in the world.
What has threatened the Great Barrier Reef?
A number of factors threaten the Great Barrier Reef. The Great Barrier Reef, like any natural habitat, faces numerous threats, largely as a result of human impact. Although it does not have an official listing of endangered, it is shrinking, and it is unknown by how much, or whether this is permanent. Climate scientists who subscribe to the theory of anthropogenic global warming (i.e. caused by man's activities) predict that the Great Barrier Reef may lose up to 95% of its coral by the middle of the current century.

There is evidence that the coral goes down much deeper than first thought, and this is an important factor in its regeneration. It is a very emotive topic. Pollution and chemical runoff pose a very real threat to the reef. The water quality of the reef is affected by sediment and nutrients, and 80% of this is caused by cattle grazing on the land adjacent to the reef. Mud and chemical runoff tend to limit the sunlight that reaches the coral, causing it to die off, and they increase the macro-algae, which is a weed. Tourism is a threat to the reef, as tourist boats damage the delicate framework of the reef; fishing and pollution left behind by visitors also is a threat. A natural threat to the Great Barrier Reef is the Crown of Thorns starfish. Outbreaks of this starfish are a constant threat to the animals of the Great Barrier Reef, though in small numbers it poses no threat. There are about 40 species which live in and around the Great Barrier Reef which are listed as endangered, mostly due to human impact.
Is the Great Barrier Reef at risk?
The Great Barrier Reef is at risk, but it is not endangered. The Great Barrier Reef, like any natural habitat, faces numerous threats and risks, largely as a result of human impact. Although it does not have an official listing of endangered, it is shrinking, and it is unknown by how much, or whether this is permanent.

What is the environmental issue in the Great Barrier Reef?
The Great Barrier Reef is subject to a number of environmental issues. Pollution and chemical runoff pose a very real threat to the reef. Mud and chemical runoff tend to limit the sunlight that reaches the coral, causing it to die off. The Crown of Thorns starfish still remains one of the biggest threats as well. It is difficult to get an answer on how much climate change is affecting the Great Barrier Reef. It is known to be shrinking, but it is uncertain by how much. Climate scientists who subscribe to the theory of anthropogenic global warming (i.e. caused by man's activities) predict that the Great Barrier Reef may lose up to 95% of its coral by the middle of the current century.

Is the Great Barrier Reef shrinking?
Australia's Great Barrier Reef could lose 95 percent of its living coral by 2050 should ocean temperatures increase by the 1.5 degrees Celsius projected by climate scientists. While the Great Barrier Reef is one of the world's healthiest reefs, coral reefs are particularly fragile ecosystems, partly due to their sensitivity to water temperature. When corals are physiologically stressed -- as is the case when water temperatures are elevated -- they may lose much of the their symbiotic algae, an event known as "bleaching." Corals can recover from short-term bleaching, but prolonged bleaching can cause irreversible damage and subsequent death.
How is the Great Barrier Reef damaged?
Fishing is dangerous for the Great Barrier Reef as many rare species of fish are being killed, which one day will become extinct. Furthermore, even just throwing litter into these waters will kill the habitats if the fish and will eventually. I was studying this topic last week in science and my science teacher told me that over the last 20 years, the reef size has gne down by 27% which is down the fact that people are damging it by pollution or fishing. Hope this helps!
