Abstract: Humans have a very large effect on the ecosystems of coral reefs. Sensitivity of coral reefs causes them to be more susceptible to harmful anthropogenic practices. Some of these are sedimentation, global warming, recreational activities, poison fishing, blast fishing practices, water pollution, and coral mining. All of these very different practices can effectively end up with the same results; the mortality of coral reefs around the world. Coral reefs are an important ecosystem of the world, and support many different industries and millions of people.

They are also the largest biological structures on the planet. The Great Barrier Reef, along the eastern coast of Australia, covers over 2000 kilometers and is said to be visible from the moon (Goreau, 1987). While the size of coral reefs can be enormous, their real impact is on a much smaller scale. Reefs function as food and shelter for fish and marine invertebrates. While the coral itself is an animal, through a symbiotic relationship with the unicellular algae, coral becomes the primary producer in its ocean ecosystem (Richmond 1993).
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.
Following are top seven aquarium across the world: 1. Churaumi Aquarium Okinawa, Japan: It's the largest aquarium in the world to earn that title and holds 21,000 animals of 740 different species that recreate the Sea of Okinawa. It has a capacity of 7500 cubic meters of water. The acrylic panel has dimensions of 8 by 22 meters and such strength is more than necessary to separate the whale shark is a species that is rarely seen in captivity and may commonly found wandering near the surface in tropical and subtropical waters from around the world. They can grow up to 20 meters and weigh more than 12,000 kilos.
It is one of the world’s most urbanized countries, with about 70 per cent of the population living in the 10 largest cities. Most of the population is concentrated along the eastern seaboard and the southeastern corner of the continent. Immigration is an important feature of Australian society. Since 1945, over six million people from 200 countries have come to Australia as new settlers. Migrants have made a major contribution to shaping modern Australia.
Waimea Canyon, at over 2500 feet deep, is Hawaii’s largest erosional valley. Nearly 50% of Kauai’s 111 miles of coastline are lined with beautiful beaches, derived mainly from erosion on reef producing coral and algae. Kauai is the fourth largest of the seven major islands in the chain and was built by a massive volcano, of which Mount Waialeale, at 5,148 feet, is the eastern rim. Kauai is located in Polynesia and in the center of the Pacific Ocean. It’s 22N of the equator and 158W and is located just below the Tropic of Cancer.
Eleven islands have an area of more than 1000 sq mi (more than 2600 sq km) each and have a huge amount of the population. These islands are Luzon, Mindanao, Samar, Negros, Palawan, Panay, Mindoro, Leyte, Cebu, Bohol, and Masbate. The total area of the Philippines is about 120,000 sq mi (about 300,000 sq km). Manila is the capital and largest city of the Philippines. Physical Characteristics The Philippines are the most northern group of islands in the Malay Archipelago, extending about 1150 mi (about 1850 km) north and south between Borneo and Taiwan, and the eastern and western size is almost 700 mi (almost 1100 km).
