GREAT BARRIER REEF Hi everyone, and welcome to my presentation about the Great Barrier Reef. My presentation is divided into 7 parts and at the end I want to show you a quick video. Let me begin by explaining what a Reef is. → Coral Reefs are large underwater structures composed of rocks or of the skeletons of small animals called corals. Next, I will give you general information's about the Great Barrier Reef. →It is located off the north coast of Australia in the South Pacific. It runs from Torres Street to Lady Elliot Island. It consists of 2900 individual reefs and around 1000 islands. All coral reefs together have an area of 600,000 square kilometers. Because of its huge size, it is divided into 5 sub-areas: Far Northern Section, Northern Section, Cairns Section, Central Section, Southern Section Next, we will have to take a quick look to the discovery. →James Cook discovered in 1770 the great barrier reef. →Due to a strong storm, he was forced to sail along the coast and anchor there in a bay. →When the storm was over, his ship sailed on a coral reef on the ground. So, now you know who and how the great barrier reef was discovered. Let's now turn to the origin. →The northern part is the oldest, about 20...

million years old. The reef spread southwards due to the lowering of the seabed and the rising sea level. The central and southern part was formed about 2 million years ago. And the parts that are visible today are about 10,000 years old. Types of reefs →Riffs can also be subdivided. First there are reefs that are called deepwater reefs. They are many hundreds of meters under water and the temperature is below 20 degrees. It's cold and dark there. →The second is the Tropical Reef, which is usually associated with the many other types of reefs. Their temperatures are usually over 20 degrees and as the name suggests they are very tropical. They are popular for their clear water and that it is not too deep. Last but not least I would like to talk about the wildlife. →The great barrier reef has a lot of animals. More than 1.500 species of fish, 411 types of hard coral, 134 species of sharks and rays, 6 of the worlds 7 species of threatened marine turtles And more than 30 species of marine mammals →I will show you here pictures of some famous animals. Let's move on to the living together of the species. →Algae get a safe habitat and carbon dioxid →Corals get glucose from the algae →Small fish use the corals as a hiding place and find food →Defend corals against predastors Now you saw the beautiful great barrier reef! But not everything looks so good, because slowly everything is destroyed, and it already started. I will show you why it's treat by human: →Overfishing, Ocean acidification, land reclamation, divers, global warming, cables and oil pipelines and a lot of waste are the reason for the destroying. Finally, I would like to stand up for action against this destruction. Examples would be: →Restriction of fishing Reduction of polloution Ban on the development of new harbours Combat diving patrols Restrict tourism Create artifical reefs Finally, I'd like to show you a video, so you can have a closer look at Great Barrier Reef. ➜ https://youtu.be/JUEEDCPa7e0 Great Barrier Reef official IMAX Trailer- MacGillivray Freeman Thanks for listening.
