1. Threats to the Great Barrier Reef \What are the threats to the Great Barrier Reef?\ In contemporary‚ the Great Barrier Reef has emerged numerous threats to the situation‚ in spite of the fact that it fetches billions of dollars into national economy from over two million tourists and over 700 tourism operators every year and supports more than 50 000 jobs. Furthermore ‚ (“Great Barrier Reef‚”2009) 2.1 Threats to the Great Barrier Reef of human factor One of the part of the risk

Bottom Trawling Imagine a coral reef‚ filled with life‚ being demolished to just bits and pieces. Unfortunantly‚ this is what happens with bottom trawling. Bottom trawling is a major issue because it damages the eco-system and it kills much more than needed. To begin‚ the destruction of bottom trawling is severe. In the process‚ a 5 ton net with weights is trailed along the ocean floor; destroying everything in its path. Fish are swept into this net and coral is completely turned into dust

(Endangered Species International [ESI]‚2011) Dynamite fishing (homemade bomb) is set off under water to kill fish for easy collection. Dynamite fishing has contributed to massive destruction of Southeast Asian coral reefs over the past 20 years. Large blasted areas are very slow to recover because corals have difficulty establishing on loose or sandy substrate. In southern Philippines‚ between Malaysia (Borneo) and Philippines (Palawan) illegal dynamite fishing is still a common practice. The area between

Corals are an outstanding example of symbiosis‚ in which a coral polyp (an animal) and an alga (which photosynthesizes) live together and benefit each other. Together‚ these partners build some of the largest structures created by any living organism. The Great Barrier Reef is the longest coral reef in the world. Coral reefs are renowned for the diversity‚ beauty‚ and the economic importance of the

In Meera Dolasia’s article “Ingenious Coralbots May Help Restore Coral Reefs” she develops the use of technology to save the coral reefs as a strong central idea. To begin‚ the use of technology to help lower the risk of these coral reefs being destroyed is a

features of the environment. An Ocean habitat is a place where communities of organisms live. The three main ocean habitats of the ocean are the open water‚ the soft sandy to muddy bottom and the hard shore. Examples of ocean habitats are the coral reefs‚ the estuaries and the abyssal zone. Habitats can be classified in a number of ways in order to compare them at different times‚ across different geographic areas‚ and in terms of different life history strategies. Habitats are as varied as the

Species Diversity and Genetic Diversity The Great Barrier Reef is located of the coast of Brisbane in Australia‚ stretching from the tip from Cape York Peninsula to Bundaberg with the length of 2 600km. It is the largest world’s largest coral reef system composed from over 2 900 individual reefs and covering an area of 344 400km2

balance. Another example is coral reefs which serve as a home to thousands of fish in the ocean such as the parrot fish. Parrot fish eat coral reefs and if they don’t have a predator to control their population size it could be detrimental to the coral reefs. The parrot fish would become overpopulated and all these fish would eat away the coral reefs. (TEDxYouth). The ocean’s ecosystems would collapse without coral reefs. Many species are at risk of extinction without coral reefs; even humans would be

Biscayne National Park is home to large numbers of threatened and endangered species of plants and animals both above and below the water’s surface. Biscayne National Park also protects one of the world’s longest coral reefs and the longest mangrove forest. Biscayne National Park‚the largest marine park in the National Park Service‚ is important
