Australia contains the world’s largest reef system stretching 2,000 kilometers along the northeastern coasts (“Australia’s Great Barrier”). The extremely ancient Great Barrier Reef, hosting millions of living things has been studied to be as much as twenty million years old. The area of the United Kingdom, the Netherlands, and Switzerland combined would still be smaller than the Great Barrier Reef, which can be seen from outer space. The Great Barrier Reef is one of the most diverse ecosystems on Earth. Being the home of ten percent of the World's total fish, it has been established that over 1,500 species of fish live on the reef.
Inside the reef there are about 2,500 various reefs of different sizes and shapes, and forms more than 900 islands, ranging from small sandy deposit massively huge vegetated structures of coral, to enormous mainland islands. All in all these scenes and seascapes give probably the most breath-taking oceanic landscape on the planet. The latitudinal and cross-rack contrast, added with special qualities through the insights of the water segment, consolidates a comprehensive astounding bunch of ecological gatherings, natural environment and different species. These various characteristics of species and organisms, and their inter dependency, makes the Great Barrier Reef one of the richest and most complex trademark organic frameworks on earth. There is no other World Heritage site that contains such varying biodiversity at a place.
The North American Great Lakes are unique among the world 's large lakes, in that their basins are linked together and form one continuous drainage basin. Together, they constitute the greatest freshwater system on Earth, covering an area larger than Texas and about half the size of Alaska. The Great Lakes today hold an estimated six quadrillion gallons of water, a fifth, or 20 percent, of all the drinkable water on the surface of Earth. If all the water in the Great Lakes were spread evenly over the continental U.S., the 48 states would be flooded under more than nine feet of water. The water surface area of all the Great Lakes is 95,000 square miles (245,759 square km).
Not only is Australia home to the Great Barrier Reef, but it is also the only continent in the world that is its own country. The Great Barrier Reef is the world 's largest coral reef system that stretches 1,250 miles off the Northeast coast of Australia. The coral reef support much of the marine life such as fish, sea turtles, and other marine mammals. In 1981, the United Nations Educational, Scientific and Cultural Organization, became in charge of the environmental protection of the Great Barrier Reef. Research found that because of the acidity in the ocean, the coral reef is at its slowest growing rate in at least 400 years.
Calculations for tourism for the year of 2015 are unavailable at this time, but for the year of 2014, the reef received a total of 2.19 million visitors. It is a well – known piece of information that there is a global climate change going on where there is a rise in CO2 in the atmosphere due to higher emissions of fossil fuel and more deforestation occurring. The ocean then absorbs more of this CO2, which in turn raises the acidity, which in turn creates a poor environment for the coral to live and recover from bleaching that has already occurred. This change in acidity also affects the calcium carbonate that corals use to build themselves. (“Climate Hot Map- Global Warming Effects Around the
Above sea level, the highest point of the island is measured at 235m, it is between 5km and 25km in width, and is 122km in length. The majority of the eastern section of the island is a flat, continuous sandy beach (Stewart, Hobson, 2006). With over 230 bird species inhabiting Fraser Island, its community of birds is recognised as being one of the biggest and most diverse in Australia (Mühlhäusler, Peace, 2001). Terns, gulls, pelicans, pied oyster catchers, and crows, as well as birds of prey species including peregrine falcons, brahminy kites and white-breasted sea eagles are among the wide variety of birds that are found along Fraser Island beaches (Mühlhäusler, Peace,
Research Paper Over the past couple years the Great Barrier Reef, off the coast of Australia has had a tremendous bleaching event which has affected the coral reefs and marine life. Around the 1990’s to present time scientists that live in the United States have travelled to the coast of Australia to find out why global warming is happening in these areas. This reef is one of the natural wonders being uniquely seen from the Earth's orbit.The rising temperatures in of the water has impacted about 1,400 miles of ecosystem including marine life and coral reefs. Along with about 1.6 million dollars to decrease the amount of reefs death. People across the whole world have been bickering about a reconstruction of these reefs because this bleaching
The Great Barrier Reef- a fragile ecosystem 1 Australia- a country of diversity No matter how far I have traversed around this earth, I have yet to find another location that rivals Australia. Nowhere else on earth can you find such spectacular landscapes, such unique and fascinating animals, and such warm friendly people. This is why I will always call Australia home. 1 This is a quote by Adam Cropp, who grew up in Port Douglas, Australia.2 He travels around the world regularly but still thinks Australia is the most beautiful and varied country in the world. Australia truly has many assets: big, beautiful and multicultural cities like Sydney or Canberra, an interesting, but sad past about racism and segregation of the indigenous people
The biggest threat to the coral reef’s future is climate change, which affects the temperature of the water and causes coral reefs to die if too hot, or too cold. 70% of coral reefs worldwide are being damaged by climate change, and not only the Australia Great Barrier Reef. Pollution, including sediment, nutrient and pesticide pollution from heavy rain, is impacting severely the health and resilience of the reef’s ecosystem. The amount of sediment flowing into the sea had quadrupled over the past 150 years, caused by the grazing and cropping expansion that brings fertilizers and pesticides into the sea. Petrol released by boats and factories, is then flowed into the sea, harming the coral reefs as well as sea life.
At the same time, this economic development has had severe ramifications for the natural environment. There has been a dramatic increase in the demand for natural resources of all kinds, including water, land and energy. Forest resources have been depleted, triggering a range of devastating secondary impacts such as desertification, flooding and species loss. Moreover, poorly regulated industrial and household emissions and waste have caused levels of water and air pollution to skyrocket. China's development and environment practices have also made the country one of the world's leading contributors to regional and global environmental problems, including acid rain, ozone depletion, global climate change, and biodiversity loss.
