The reef protects the Channel form Harsh winds and waves from the Coral Sea therefore making the waters calm. Island and ringlets are scattered across the Choral Reeef. These are often referred to as Atolls or Cays, which range in size up to 300000 square Kilometeres. And make ship navigation especially difficult. Te Atolls are home to billions of different species of animals, which include [IMAGE] - Varieties of dolphins and whales, -Dugong and green turtles, - More than 1500 species of fish -200 species of bird life -4000 types of mollusc and many many more.
One topic that came to mind while researching this paper was the Great Barrier Reef, which I had wanted to research for my presentation, but information was more abundant for the topic I did choose. The size of the reef and its tourist potential are great in their respective ways. The reef is the largest of its kind extending 2300 km along the North East Coast of Australia from Cape York to the northern part of South Queensland. Most may believe that the reef alone is one large organism, but is amazingly a network of roughly 2900 individual reefs to form one large reef that is roughly the size of the U.K. The remains of what are called polyps form the reef.
Thousands of fish and invertebrates live in association with reefs, because of the complexity. For example, in Caribbean reefs, several hundreds species of colonial invertebrates can be found living on the undersides of platy coral. It is common for a reef to have several species of snails, sixty species of coral, and many species of fish. Out of all oceanic habitats, reefs seem to have the greatest development of complex symbiotic associations. Coral reefs are very important to humans as well.
Consequently, the Government and other organizations have been looking at ways to increase the reef's resilience, to better cope with this problem. On the whole, much is being done to benefit the reef. However, with the increasing threat of climate change, there is still a great deal that needs to be done to secure the reefs future. Costal runoff has a detrimental impact on the Great Barrier Reef, as well as other problems which are associated with it. Since the arrival of European settlers, farm practices have changed dramatically.
As with other coral reefs, it is based upon the structure of billions of coral polyps, and the GBR is the longest coral reef system ever to exist. It is consequently the largest structure created by living creatures and so massive that it can be viewed from outer space (Guynup p.22). The GBR includes 2,900 separate reefs and hundreds various islands and cays. The GBR stretches over 2,000 kilometers up the coast of Queensland. The Great Barrier Reef Marine Park (GBRMP), established in 1975, includes nearly 350,000 square kilometers, which is over half the area covered by all of the protected areas in mainland Australia (Chadwick and Storrie p.1, CRC p.1).... ... middle of paper ... ...w.gbrmpa.gov.au/ Guynup, Sharon.
This reef is off the coast of Queensland, Australia. It stretches more than 1,800 miles and tops 40 miles wide in some areas of the coral reef. This reef is so massive that you could see parts of the reef from outer space! This reef is made up of over 600 types of hard and soft corals; and over 3,000 individual reefs systems. This coral has 30 species of whales and dolphins; 1,625 species of different types of fish, 33 species of sharks and rays.
Coral reefs are an important ecosystem of the world, and support many different industries and millions of people. Introduction Coral Reefs are said to be the “tropical rainforest” of the sea. They are home to over 25% of all marine life (http://coralreefalliance.org.stories/storyReader$77). Over the past few decades they have been subjected to destructive anthropogenic practices. Some of the major threats to coral reefs include sedimentation, water pollution, harmful recreational activities, and global warming.
Because the reef is so large it is considered to be one of the “seven natural wonders of the world” (greatbarrierreef.org). According to unmuseum.org/7wonders/greatreef.com, the Great Barrier Reef is more than 1600 miles long and it covers an area of more than 133,000 square miles. The reef system is composed of over 2900 individual reefs and has over 900 islands. The complete system is larger than all of Italy put together (greatbarrierreef.com) which is equal to about 70 million soccer fields (greatadventures.com.au/great-barrier-reef.info). The Great Barrier ...
This is concerning because the sea temperatures are also rising. Healthy sea temperature is vital to reef building and controls the speed of coral reef development. Escalating sea temperature is endangering distribution and diversity of marine life. In conclusion, the Great Barrier Reef is in danger due to climate change issues such as ocean acidification, greenhouse gasses and many others previously discussed. In order to protect the reef, changes in society need to be made.
On a June evening in 1770, British explorer, Captain James Cook heard the irritable screeching of wood against stone. Little did he know, he had just discovered the Great Barrier Reef! Off the coast of Queensland, Australia in the Coral Sea, the GBR is the world's largest reef system, it can even be seen from space! It is approximately 35 million hectares, which equals about 70 million football fields. The GBR hosts an extremely diverse array of marine life from mollusks to fish to sea and shore birds.
