Why does pollution affect the Great Barrier Reef?

Pollution can disrupt and destroy the precious ecosystem that is the Great Barrier Reef, depending on the type of pollution. Faecal matter can poison certain organisims living within this ecosystem. Toxic chemicals can kill most organisms living on the Great Barrier Reef, such as mercury. Increased water temperature is also considered a pollution, caused from global warming, and can speed up the occurance of coral bleaching of the GBR's corals.

What is the structure of Kakadu National Park and The Great Barrier Reef?

Kakadu National Park consists of a variety of natural items typically seen in the rugged and remote wilderness of far northern Australia. There are massive, ancient rainforest trees; sheer cliffs and waterfalls; unusual, towering rock formations and expansive wetlands. Kakadu is not just rainforest; the wetlands are recognised for their international significance under the Convention on Wetlands of International Importance.

The Great Barrier Reef is composed of coral formed from the skeletons of living organisms.It extends for some 2,300 km parallel to the Queensland coast.

Where is the Great Barrier Reef?

Considered one of the great natural wonders of the world, the Great Barrier Reef sits off the northeast coast of Australia. It is located in the Coral Sea and extends for a length of around 2300 km down the coast of the eastern state of Queensland. It is actually a series of reefs and atolls, with its northern end just south of Papua New Guinea. It is the largest coral reef in the world. Australia has almost one-fifth of the world's reef area most of which is located in the Great Barrier Reef. It is the largest structure on earth created by living things, hosts millions of ocean-living creatures, and can be seen from space.

What is the length and area of the Great Barrier Reef?

Figures vary, but according to the Australian Institute of Marine Science, the Great Barrier Reef is approximately 2,300km long. It is located in the Coral Sea and lies parallel to the coast of Queensland. It is actually a series of reefs and atolls, with its northern end just south of Papua New Guinea, and its southern end near Lady Elliott Island, northeast of the city of Bundaberg. This is the equivalent of about 1,430 miles.

Australia has almost one-fifth of the world's reef area and most is located in the Great Barrier Reef, off the eastern coast. The Great Barrier Reef World Heritage Area, which comprises more than just the coral reefs, atolls and islands of the Great Barrier Reef, covers around 348,000 sq km (134,363 sq miles) while the Great Barrier Reef Marine Park itself covers around 344,400 sq km.

Is the Great Barrier Reef shrinking?

The Great Barrier Reef is 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.

How is the Great Barrier Reef going to be helped in the future?

It most likely won't be helped, but it will be destroyed by a special type of starfish if we can't kill them first. Do a Google� Images� search for "Thorn Of Crowns Starfish, Great Barrier Reef" Or do a normal Google� search, if you don't get any images. Try separating them. The Starfish is only able to be killed by a snail, one that has a harpoon filled with poison at the tip. This doesn't really answer your question, but it tells you how to find the answers. Good luck, my friend. In many countries they are sinking old ships so plankton will grow on it and try to bring back the natural order of the oceans. Depending on what the trouble is you are worried about. As for the star fish problem we can't really fix that too easily. We would have to start hunting starfish, which for some reason environmentalists don't like.

If your concern is that the reef will die as the water level rises then you shouldn't fear. Coral grow where they can survive. Meaning they won't be growing downwards into the colder water. They naturally grow upwards towards the heat of the sunlight. This means as the ocean levels rise the reef will grow upwards too. Thus our beloved reef that has wrecked many a ship is saved, by itself.

= Great Barrier Reef = The Great Barrier Reef includes over 2,900 reefs, around 940 islands and cays, and stretches 2,300 kms along the Queensland coastline. The Great Barrier Reef Marine Park is 345,000 km2, that's larger than the entire area of the UK and Ireland combined! Bullray swimming in the Great Barrier Reef

© WWF-Canon/Jürgen FREUND The reef is immensely diverse with 1,500 species of fish, 359 types of hard coral, one third of the world's soft corals, 175 bird species, six of the world's seven species of threatened marine turtle and more than 30 species of marine mammals including vulnerable dugongs. Add to that stunning marine life are 5,000 to 8,000 molluscs and thousands of different sponges, worms, crustaceans, 800 species of echinoderms (starfish, sea urchins) and 215 bird species, of which 29 are seabirds. The Great Barrier Reef is listed under all four natural World Heritage criteria for its outstanding universal value. Protecting the reef has benefits beyond conservation - it is also an investment that helps provide security for coastal communities and provides significant benefits to the Australian economy. Reef industries, which are reliant on a healthy environment in which to operate, contributed approximately $5.8 billion to the Australian economy in 2004 and employed about 63,000 people. Historically, the Reef has been regarded as a well-protected, pristine wonderland - a place of delicate corals, abundant fish life and a haven for other marine life. As scientists came to understand more about the reef's complexities, a different picture emerged - overfishing, land-based pollution and coral bleaching exacerbated by increased sea temperatures due to global warming are all impacting upon its natural wealth. Immediate action was required to protect the reef because only 4.6% of the reef was fully protected. As a result of public campaigning and pressure from WWF, the Australian Government committed to a plan to protect 33% of the reef. The Great Barrier Reef Marine Park (GBRMP) zoning plan was implemented in 2004. Its most significant feature is a network of marine sanctuaries that stretch from the Park's northernmost to southern boundaries. This is the world's largest network of marine sanctuaries and covers over a third of the Marine Park - protecting over 11 million hectares. Scientists have identified 70 different distinct biological regions in the GBRMP, representing the entire range of its plants and animals. A minimum percentage of each biological region is protected from fishing in order to maintain the health and resilience of the ecosystem and to protect the full range of biodiversity in the marine park. Crown-of-thorns starfish - one of the threats to the Great Barrier Reef

© WWF-Canon/Jürgen FREUND The amount of sediment flowing from the land into the marine park from its catchment area has quadrupled over the past 150 years due largely to grazing and cropping expansion in the catchment and loss of native vegetation and wetlands. The reef has experienced two mass coral bleaching events - in 1998 and 2002. Bleaching was more severe in 2002, with aerial surveys finding that almost 60% of reefs were bleached to some degree. Not only is the reef subject to high levels of fishing pressure, other fishing practices such as seafloor trawling for prawns are still permitted in over half of the marine park, resulting in untargeted fish capture (by-catch) and destruction of the seafloor. Maintaining a well funded, enforced and monitored network of marine sanctuaries throughout the GBRMP is essential to protect representative areas, as well as areas that are of special or unique biological value. Healthy levels of fishing effort in the marine park are needed to safeguard the Reef's biodiversity. The joint Australian and Queensland governments' Reef Water Quality Protection Plan confirms that effective action must be taken now to reduce land-based sources of sediment, nutrient and pesticide pollution further damaging in-shore reefs. The future impacts of global warming must be included in government plans regarding the Reef at a local level, and action must be taken at a national level to reduce CO2 emissions.

How was the Great Barrier Reef formed?

The Great Barrier Reef was formed by nature, with hundreds of years of living coral building upon the skeletons of other coral.

The corals that build reefs are not single animals. Coral is made up of colonies comprised of many individual animals called polyps, which join together. Coral polyps are a little like sea anemones, having tentacles that extend outwards, but they are not actually anemones.

Corals which create coral reefs have a symbiotic relationship with algae known as zooxanthellae. This algae, which lives within the tissues of the coral, causes a photosynthetic reaction which enables the polyps to make skeletons about three times faster in the light than in the dark. This means the corals deposit skeletons faster than the environment can remove it, and these skeletons build upon each other over time, creating a coral reef.

What are the difference of corals and coral reefs?

A coral reef is a colony of corals. A coral reef can be formed on rock rubble, but old established coral reefs are actually structured out of dead coral. This is one of the reasons it takes so long for a reef to form. Some corals may life for tens or even hundreds of years before they die and allow another coral to grow on top of their skeleton.

There are many types of coral reefs, but the real difference is that coral is what makes up a coral reef.

How far is the Great Barrier Reef from shore?

At its most southern end, the Great Barrier Reef is about 200km from the coast of Queensland. Its distance from the shore becomes less, the further north it goes. By the time it is parallel to Cairns, it is quite close, within a few hundred metres, and many tours to the Reef operate from Cairns.
