Why Shark Bay (Australia) is a World Heritage Site
Shark bay is recognised as one of the worlds heritage sites as it fits
into all four of the major categories they are:
* “ as an outstanding example representing the major stages in the
earth’s evolutionary history;
* as an outstanding example representing significant ongoing
ecological and biological processes;
* as an example of superlative natural phenomena; and
* Containing important and significant habitats for in situ
conservation of biological diversity.”

The shark bay region has a number of plant species that are threatened
and the last of their kind.This contributes to the beautiful flora and
importance of the area.
Shark bay is well known for its beautiful marine fauna. The
populations of animal life in this area are of great numbers. This
contributes to its importance of being on the world heritage list.
The region is also noted for the diversity of many reptiles and
amphibians they have adapted very well to the stromatolites in this
area and have used theses formations as there homes.
There are in fact 12 species of sea grass in Shark bay which make it
one of the most varied seagrass areas in the world. These Sea grasses
have contributed significantly to the evolution of Shark bay and along
side which the cyanobacteria have made many homes for the vast variety
of organisms existing.
The barrier banks associated with the growth of the sea grass over the
last 5000 years as well as the low rainfall has contributed to the
saline Hamelin Pool and Lharidon Bight. These very salty conditions
are best for the reproduction and growth of the cyanobacteria which
trap and bind sediments to produce a variety of mat and other
structures including stromatolites.
Stromatolites are found at shark bay and they represent the oldest
form of life on earth. The saltiness of this area has the best
conditions for the growth of cyanobacteria which trap and bind
sediment to produce a variety of mats and structures including these
Every year hundreds of sharks get killed just because people fear them. Western Australia has brought in the Shark Culls after a series of fatal attacks. Most of these people attacked are usually surfers, swimmers or shark haters. Now imagine this, what if you were a shark swimming and suddenly someone tries to hunt your down, how would you feel? We wouldn’t like it very much if the sharks did the same thing to us. In the following paragraphs, I would give you three reasons on why Shark Culling should be abolished not only in Western Australia but also all around the world.

The Chesapeake Bay is the nation’s largest estuary with six major tributaries, the James, the Potomac, the Susquehanna, the Patuxent, the York, and the Rappahannock Rivers, feeding into the bay from various locations in Maryland, Virginia, Pennsylvania, and the District of Columbia (Chemical Contaminants in the Chesapeake Bay – Workshop Discussion 1). These areas depend on the Bay as both an environmental and an economic resource. Throughout the last 15 years the Chesapeake Bay has suffered from elevated levels of pollution. Nitrogen and phosphorous from wastewater treatment plants, farmland, air pollution, and development all lead to reduced water clarity and lowered oxygen levels, which harm fish, crabs, oysters and underwater grasses (Key Commission Issues 1). There are other types of pollution in the bay such as toxic chemicals, but because nutrient pollution is the most significant and most widespread in the Bay its effects are the most harmful to fisheries. Nitrogen and phosphorous fuel algal blooms which cloud the water and block sunlight from reaching underwater grass beds that provide food and habitat for waterfowl, juvenile fish, blue crabs, and other species (Blankenship 11-12). Algae plays a vital role in the food chain by providing food for small fish and oysters. However, when there is an overabundance of algae it dies, sinks to the bottom of the Bay, and decomposes in such a manner that depletes the oxygen levels of the Bay (11). The reduced oxygen levels in the Bay reduce the carrying capacity of the environment and these “dead areas” sometimes kill off species that can not migrate to other areas of the Bay, such as oysters (11). Increased abundance of algal blooms also led to the overabundance of harmful and toxic algae species and microbes such as the microbe Pfiesteria, which was responsible in 1997 for eating fish alive and making dozens of people sick (12). The heightened awareness of diseases that can be contracted through consumption of contaminated fish also has an economic impact. Therefore, the excess levels of nitrogen and phosphorous have fueled an overabundance of algal blooms, which has reduced water clarity and lowered oxygen levels, affecting many species within the bay and ultimately the industries that rely on these species.
Earth, an endless source of wonder and beauty, produced the Great Barrier Reef. Hustling and bustling, the Reef thrives like a busy city, teeming with life. Sheltering thousands, corals, maintain the well-being of the Reef; however, the world threatens its nature and delicacy. Populations growing and technological advances increasing, the world becomes more and more disconnected with the natural world, posing an alarming risk for the planet we live on. Although many organizations try to keep the oceans clean, because of human interference and unnatural occurrences, the Great Barrier Reef needs scientific help to adapt corals to new conditions for means of survival, putting pressure on the Australian government to save their ocean environment.
I’m Yukina Yasuda. I'm here to ensure you that the great barrier reef is best icon for Australia.
The Great Barrier Reef is home to a remarkable number of organisms. The coral itself is made up of the skeletons of tiny, flowerlike water animals called polyps, held together by a limestone substance produced by a type of algae. Hundreds...
In my research, the Oceans of Kansas organization for Paleontology has given me more than enough to focus on when depicting out how to correlate our modern logic about how Kansas is mostly a wasteland to when it used to be an ocean with striving life within. The sharks that have been recently discovered are increasing not only in size, but by type. Mike Everhart, lead Paleontologist of this organization, in April 2002 discovered an extremely large shark called the Cretoxyrhina Mantelli "Ginsu Shark". “A large lamniform shark found worldwide from Turonian into Campanian time during the Late Cretaceous. Much the same size as a modern Great White (but not closely related), the Ginsu shark reached lengths of more than 6 meters before becoming extinct about 82 million years ago.
One of the previous papers in English class required the class to pick a paper to explore, this question will be concentrated on further in the synthesis essay. What evidence do scientist have to prove that prehistoric sharks existed? The reason behind picking this question wasn’t just to find proof that these monsters swam the seas, but to learn more about them from different resources. One of the resources that were used was a chapter in Angelo Mojetta’s book Sharks, called “ The Birth Of A Legend”. The other resource that was used for information was an article in Discovery Channels website called “ Prehistoric Sharks”. Sharks and Discovery Channel are the two resources that led to many other questions about their different, and similar views on prehistoric sharks existence.
The Chesapeake Bay has faced an excessive amount of pollution over the past century. The water in the bay has become so highly polluted that It is capable of causing harm to humans coming in direct contact with the water. Although algae serves a vital role in the bay’s ecosystem, it also creates a problem that is causing a large amount of the problem.
Sindney W. Mintz, “The Caribbean as a Socio-Cultural Area,” in M. Horowitz, Peoples & Cultures of the Caribbean (Garden City, N.J., 1971).
The Caribbean is often overlooked when the concept of slavery is discussed. However, the Caribbean islands played an integral part in the building of various countries’ economies around the world; primarily European countries. Many of the social stigmas that are associated with slavery are still present in various Caribbean countries’ societies today. Caribbean cultures have very strong African roots as of the numerous traditions carried from Africa by the slaves. This paper will give an overall view of slavery in the Caribbean and go more in depth into the economic, social, and cultural affects that it had and is still giving in the Caribbean using Haiti as a focal point.
Throughout history an even today, Caribbean scholars contend that Caribbean relations are characterized by an interplay of race, class and gender. Clarke agree with this statement and said that, “The social structure of the Caribbean region is based on differences associated with class, race or colour, ethnicity and culture (Clarke, 2013). These three (3) components of race, class and gender affect each other in one way or the other. In other word, one’s class position may be dependent on his or her race or gender or one’s gender may determine his or her class position in society. It is important to note that the interplay of race, class and gender in the Caribbean differs from island to island. This essay will discuss the extent to which
Caribbean music is formed based on the tradition of Calypso, Soca, Zouk, and Reggae. They own a diversity style music since being bordered by the islands of Jamaica, Haiti and Trinidad. Morden community has fight for their independence and some islands won their or being a part of invading country only. Specially is the freedom of Cuba, Haiti and Jamaica with their self-sufficient and others now belong to the United States. These things had happening at the sametime that broke the Caribbean culture apart and created a diversity history.
Natural has its own world in St. Martin. The island is about two kilometres long and the deep blue water all around it is outstanding to watch. Rocks of different sizes and types are all around the beach, some of which are with razor sharp spikes that can cut your foot into pieces if you step on them. Moreover, different coloured sea weeds and live corals can be seen on the rocks which are submerged in the water. St. Martin is the only Island in the world with live corals. There are more than thousands of different types of coral in this island. Scientists say that this island actually grew from this coral by the metamorphosis of different c...
World Heritage Areas embody the diversity of the planet, and the achievements of its peoples. They are places of beauty and wonder; mystery and grandeur; memory and meaning. In short, they represent the best Earth has to offer. The pyramids of Egypt, the Great Wall of China and the Taj Mahal are some of the most outstanding examples of humanity’s cultural achievements. The Great Barrier Reef, the Galápagos Islands and Serengeti National Park are among the world’s greatest natural treasures. All of these places are on the World Heritage List.
