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 coral reef called the rainforest of the ocean?
It is very simple. Reef tanks are beautiful and exotic and for some a piece of nature. Unlike the marine aquarium, the main purpose of which is to house various types of fish, the true stars of the reef tank are the coral and other invertebrates.
What coral reef ecosystems are there?
From largest to smallest:
The Great Barrier Reef (Queensland, Australia),
Mesoamerican Barrier Reef System (Yucatan Peninsula),
The New Caledonia Barrier Reef,
The Andros,
Bahamas Barrier Reef,
The Red Sea,
Pulley Ridge (Florida) and Ghe Raja Ampat Islands (Indonesia's West Papua province).

Why are coral reefs absent at the mouth of rivers?
Corals need access to sunlight (the algae living in their cells need light for photosynthesis) so the water where they grow needs to be shallow and clear. Too much sediment in the water can smother the coral polyps and too much fresh water kills them.
Name two human activities that are threatening the great barrier reef?
- Over- fishing
- Water pollution
- Global warming
- Excess CO2 in the atmosphere
- Shipping navigating through the reef, and resultant shipping accidents
- Excessive tourism activity on the Reef
- Chemical run-off from farms - pesticides and fertilisers
- Farming activities increase acidic sediment as well
- Changing water quality on the reef, due to human interference - quality such as salinity, nutrients and increased sediment concentration
- Rising sea temperatures (different to the debatable global warming, which is not necessarily due to human activities, but entirely possibly part of a natural cycle - coral cannot handle even mild increases in temperature)
What does a barrier reef look like?
The Great Barrier Reef is the name of the world's largest reef system. It is located in the Coral Sea off the coast of Queensland, Australia. It is made up of more than 2900 coral reefs and 900 islands, and extends for about 2300 km parallel to the coastline.
How many islands on the Great Barrier Reef?
There are more than 3000 Located in the Great Barrier Reef located on the Northeastern coast of Australia.
Where is the second largest barrier reef in the world?
The worlds second longest barrier reef is the un-named barrier reef approximately half a mile away from the coast of Belize.
Australia.
Are you allowed to fish at the Great Barrier Reef?
Some Great Barrier Reef snorkelling links below.
in some places you can but it Can kill the coralsAnswer:I just came back from there and snorkeled for two weeks. The reef is quite far off shore so you have to use boats, traveling at top speed for an hour and a half, to get there. But the reef is shallow and is great fun. All boats are professionally run.How have changing sea levels affected the growth of the great barrier reef?
The changes occuring to the reef are to do with the Mass Coral Bleaching due to rising sea temperatures in 1998, 2002 and 2006. Pollution and declining water quality are other reasons plus the Crown of Thorns starfish which eats coral. Other things are shipping accidents, oil spills and tropical cyclones.
Coral Shrimp feed off of the little animals in the reef..
Which ocean zone does sunlight penetrate?
The epipelagic zone is the region in the ocean that is exposed to a sufficient enough amount of sunlight to allow photosynthesis to occur.
Where is the best place to dive in the Great Barrier Reef?
The Great Barrier Reef has thousands of great diving spots. The 'best' in terms of diversity and visibility are those in the outer reef. Moore Reef of Cairns is beautiful and well recommended! As to is the diving of Lizard Island FNQ.
What habitats are in the Great Barrier Reef?

What are 3 organisms living in the Great Barrier Reef?
plankton, bacteria, sponges, and many many more i don't know...............
What are the ocean zones of a marine ecosystem from the shallowest to the deepest?
There are two major ocean zones, Pelagic and Benthic zones. The Pelagic zone is the open ocean and the Benthic zone is the ocean bottom.
How far does the Great Barrier Reef stretch?
The coral which makes up the Great Barrier reef is believed to extend to a depth of around 500m in some places. However, the living polyps only go down as far as 30 metres.
The water in the channel between the shoreline and the reef reaches about 60 metres in depth.
In what way are coral reefs essential for humans?
They are important to humans because animals in the corals reefs can be used to make medical drugs that help cure diseases, they can provide food for more that 1million people, and some lime stone reefs can be used for human bone grafts.
Is the Great Barrier Reef good or bad?
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.
What is California's state marine animal?
== == California State Fish - Golden Trout:
The golden trout (Salmo agua-bonita) is native only to California and was named the official state fish by act of the State Legislature in 1947. State Marine Fish - Garibaldi:
In 1995, the Legislature acted to protect the Garibaldi (Hypsypops rubicundus) by placing a moratorium on commercial collection until the year 2002. They also named the garibaldi the official State Marine Fish.
This quote has been attributed to Lieutenant James Cook (not yet a Captain).

Would you expect to find coral reefs growing near the mouth of the Amazon?
No, the Amazon River expells 4.2 million cubic feet of water per second. This is too great for fragile coral to ever form, even disregarding all the other reasons why you would not find coral reefs near the mouth of the Amazon.
Yes they are because they are made of coral which is living, all parts of the coral reefs are alive
