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!
The Great Barrier Reef, like any natural habitat, is damaged 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. 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. 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 damages the reef, as tourist boats damage the delicate framework of the reef; fishing and pollution left behind by visitors also is a threat. Shipping also damages the reef.
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.
tourism is doing damage to the great barrier reef by throwing litter in the water and polluting the water which is killing the corals and the whole great barrier reef.
James Cook was sailing in the HMS Bark Endeavour when it was damaged on the Great Barrier Reef in June 1770.
The Great Barrier Reef is being threatened by urban development, agriculture, oil spills, and normal pollution. Infestation and disease have damaged it. Thousands of commercial vessels have damaged it.
The Great Barrier Reef is a coral reef.
The proper name for the Great Barrier Reef is simply "Great Barrier Reef".
No. Although Osprey Reef is in the Coral Sea, where the Great Barrier Reef is located, it is actually separate from the Great Barrier Reef.
The Great Barrier Reef is a coral reef ecosystem.
The Great Barrier Reef is the largest reef system in the world.
The great barrier reef is awesome
The Great Barrier Reef has not been destroyed
The Great Barrier Reef is the world's largest coral reef.
The Great Barrier Reef was named by Matthew Flinders, the first explorer to circumnavigate the Australian continent.The Great Barrier Reef is a coral reef placed into the category of 'barrier reef'. This means that the reef is separated from the coastline due to the water's depth being too deep. The reef was given its name because of the following.Great: The Great Barrier Reef is a large and vast coral reef: at 2000km long, it is the largest coral reef in the world.Barrier: The Great Barrier Reef is a barrier reef. A barrier reef is one which runs parallel to the shore, separated by a channel of water.Reef: The Great Barrier Reef is a coral reef.
The Great Barrier Reef is always known as the Great Barrier Reef. It has no other name, although it may sometimes be shortened to just "the Reef".
