Although the Great Barrier Reef does not have an official listing of endangered, it faces numerous threats to its continued existence. Currently, it is shrinking, and 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. 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.
It should also be noted that some 40 species which live in and around the Great Barrier Reef are listed asendangered.

Why would it be bad if the great barrier was not around anymore?
The Great Barrier Reef is apart of natural history and it would be apsoluetly devastating not only for me but for many others and it is one of the seven wonders of the world. Another thing is that many people have devoted their lives to researching this natural wonder and so their lives would go to waste and so this is why it would be bad if the Great Barrier Reef wasn't around anymore.
How have humans interacted positively with the Great Barrier Reef?
People are helping the great barrier reef in a number of ways, killing and trying to control the population of crown-of-thorns sea stars is just one example. Raising money for it after natural disasters such as the Queensland floods and cyclone is another.Further information:There are numerous groups making an effort to help the Great Barrier Reef.The Species Conservation Unit monitors certain vertebrate species in the Great Barrier reef and provide specialised advice to minimise human impact and its associated risks on Protected Species.Naming and recognition of the Great Barrier Reef in 1981 as a World Heritage Area helps raise public awareness of the need to conserve the reef, as well as enabling laws which specifically help protect the Reef.The Great Barrier Reef Marine Park Authority works in assocaition with Aboriginal and Torres Strait Islander Traditional Owner groups to understand how they have managed to conserve the reef yet utilise its resources with minimal impact. Together, these two groups develop and maintain Sea Country Partnerships which will help sustain and conserve the reef.Australia is one of the countries of the world implementing a Biodiversity Action Planwhich helps to protect the Great Barrier Reef.There are regions along the coast near the Great Barrier Reef where use of chemical and pesticides by farmers is being closely monitored, in light of revelations that the chemicals are damaging the ecosystem of the Reef.Restrictions in boating, fishing, and various other activities have, increasingly, been put in place, to help protect the Great Barrier Reef from further destruction. Nevertheless, it is still an extremely vulnerable ecosystem, and remains threatened.

Why is the Great Barrier Reef a barrier?
The great barrier reef is being destroyed becuase of global warming, pollution and other factors. Most of it is due to people though.Further information:The Great Barrier Reef is not actually almost being destroyed. It does not even have an official listing of endangered: but it is shrinking, and 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 done so in the past. Destruction and regeneration is all part of the reef's natural cycle. parts of tye northern Great Barrier Reef that have been damaged during a warming cycle have been found to regenerate after just twelve years.However, it should be noted that 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.
