Coral Reefs By:Camila escareno

Basic Information about Coral Reef

Coral Reefs are made of polyps, which are tiny organisms that look like rock and as they grow the reef grows. Coral reefs are formed by large colonies of anti-sized organisms called corals. There are three different types of coral reefs barrier reefs, fringing reefs, and atolls. The largest reefs are found in the warmer portions of the Pacific and Indian ocean. Reefs are composed of numerous different species of coral. More than 350 species of coral have been found in reefs. Did you know coral reefs are naturally colorful because of it algae, so if a coral reef appears white that means there is a pollution problem.

Interesting Facts about Coral Reefs

There is a lot of things that are very interesting about coral reefs that many people do not know about, like how coral reefs have existed for more than 200 million years. Something else about coral reefs that is pretty interesting is that although many types of animals live within coral reefs, it has much more diversity in its plant life. Also did you know about ten million bacteria live in coral and 25% of marine life live in coral reefs. Another cool fact is that the Bikini Bottom from Spongebob is actually a real reef called Bikini Atoll. The last interesting fact is that coral reefs can also grow on the shells of sunken boats so sometimes people will take old ships and sink them so more corals will grow.

Things you might want to know about Coral reefs

There is lots of things you need to know about coral reefs so you can learn how they grow, live, and how to take good care of them.First of all corals are in every single ocean so make sure you don't hurt the ocean with trash.To survive corals eat plankton and other small organism. Another thing that corals must need is living in water seventy to eighty-five degrees fahrenheit. Something you must always keep in mind is that coral reefs contain some of the largest diversity of life in the world so hurting them can really hurt other animals in the ocean. Did you know that coral reefs take a very long time to grow they grow up to three centimeters a year. A coral reef needs sunlight to grow, that is why they hardly grow in waters deeper than forty-five feet. Also coral reefs mostly grow where there is stronger wind currents and wave patterns.

The Great Barrier Reef

The Great Barrier Reef is the largest coral reef in the reef. The reef and the land are separated by a shallow lagoon. Something really fascinating about the Great Barrier Reef and other reefs is that there is more types of fish living in a two acre area of coral reef than there are kinds of birds in all of North America. Did you know the Great Barrier Reef crosses over 500 islands and that it is actually made up of 900 smaller reefs. Also coral reefs cover less that 1% of the ocean.

More about Coral Reefs

Parts of Florida would have been under water, if coral reefs would have not existed. You know that over 500 million people rely on coral reefs for their food and livelihoods. Coral reefs really benefit to us because they protect coastal dwellings, agricultural land, and beaches by forming natural barriers. Also the less known coral reefs are widely used in the treatment of cancer, HIV, cardiovascular diseases, and ulcers. Did you know porous limestone skeletons of corals have been used in grafting human bones. Pacific coral reefs contain more species of fish,plants, and corals than the Caribbean because of the wind and ocean patterns.

Coral Reef Problems and History

A sewage pollution problem existed in almost 1/4 of coral reefs, but have survived since 1998. The population of coral living within ten kilometers of the Caribbean coast grew from 36 million to 41 million during 1990-2000 .Even though coral reefs are doing a little better 36% of coral reefs in the region still lie within two kilometers of inhabited land. Did you know marine based pollution such as water waste discharge from cruise ships and other vessels threaten 15% of reefs. Generally cruise ships and cargo ships contribute 77% and 20% of all ship type waste to coral reefs.

Coral Reefs Dying

The cost of destroying one kilometer of coral reefs ranges between $137,000-$1,200,000 over a twenty-five year period.Did you know more than 80% of the world's shallow reefs are severely over-fished and that 58% of the world's reefs are potentially threatened by human activity. This is why we have already lost 27% of the world's coral reefs. Many people don't know that if present rates of destruction are allowed to continue 60% of the world's coral reefs will be destroyed over the next thirty years. Properly managed coral reefs can yield an average of 15 tons of fish and other seafood per square kilometer each year. Something really interesting is that thirty-two of the thirty-four recognized animal phyla are found on coral reefs compared to nine phyla in tropical rainforest.Coral reefs are found in 109 countries and reef degradation has occurred in ninety-three.

Final Information about Coral Reefs

$30,000,000 of coastline, protection, tourism, and food are provided by coral reefs every year. 30% proportion of coral reefs have been degraded or destroyed globally. This is why 1.17% of are oceans are protected by marine reserves. A fun fact to know is that there is 5,880 marine reserves in the world. Did you know 135 kilometers of Danajan Bank, a rare and threatened double-barrier reef in central Philippines, is a total of 234,950 square hectares. Something you might not know is that 1.72 average number of lives are saved per coastal village during 1999 thanks to coral reefs. 90% of the world's fisheries yields come from waters less than 200 meters deep.
