Coral Report By: Tony Choukalas Period 6 A major problem is happening and lots of people don't know it. The reason why people don't know about it is because we don't see it. Plus people don't know that they are doing it. People are destroying the coral in all the waters of the world. Destroying the coral is a very bad thing to anything that lives in the water. Coral provides shelter for small fish, and other things. There are two things that make coral. Coral can be made like any other animal. It grows by itself. Other kinds of coral are made by tiny little fish called polyp. Inside the polyp are tiny algae, and these algae excrete tiny amounts of limestone. This limestone collects together to form a type of coral. There are so many things that we do that destroys coral. Most of it is something that we can control. But not many people are doing anything about it. Sedimentation is one danger that is hard to control. Any kind o construction, mining, farming or logging near oceans will hurt the coral. As we do any of those things dirt, silt and/or sand gets into the water and makes the water cloudy and murky. When the water gets cloudy it cuts off the sunlight. Coral need the sunlight to survive. A big problem that affects more than just the coral is human run-off. Fertilizers and sewage are dumped into waters and this can make algae grow at a rapid rate. This chokes the polyps by cutting off the light and oxygen. Fishing with explosives is one of the worst ways that coral is being destroyed. Since we have started fishing and taking lots of fish from the waters some places are over fished and there aren't any left or very few. The few fish that haven't been caught hind in the coral. Fishermen make explosives that are made from a common fertilizer and put them in the coral. They are then detonated and totally destroys the coral and the dead fish are then scooped up. There is something less destructive but still kills fish and the polyps. Fishing fleets dump cyanide into the water to poison the fish. This method of catching fish is mainly used in the tropical areas and recently for "live fish" restaurants. Since this method was used in the Philippines, more than 400 thousand barrels of cyanide and other poisons have been dumped into the water every year. Only 10% of their coral still remains healthy. One that you or I would probably never would have thought of would be that coral is used in construction. It is used for making materials in roads (very few use it though). It is also sold as souvenirs. Even though not much coral is sold as souvenirs or used in construction, it still contributes to the destruction of coral. Water pollution is a big killer to coral. Coral is hurt by just about anything that is some kind of petroleum product, chemicals, or trash that is dumped in the water. The chemicals and petroleum products can kill the polyps and blocks sun from the coral. The trash that is thrown into the water gets caught in the coral and can cause pieces to break off. Since we have discovered the global warming problem scientist have found that it is hurting the coral. It causes the coral to be bleached or turn white. Bleaching is just another way of saying that it kills the coral. Plus global warming also causes huge tropical storms that can crush the coral. So far there aren't many ways to help the coral. People have tried to just leave the coral alone and see if it would heal itself. But depending on the amount of damage done determines whether the coral will come back. Scientists are growing coral in their laboratories. Once the coral is at a point at which the scientists think that is can be put in the ocean it is attached to a metal board and placed in the ocean. Eventually the board will be covered up and the coral will live a normal life. The problem with this, is that the coral doesn't grow fast enough so it can be placed into the ocean. There would have to be lots and lots of places in order to make it all. Many organizations have tried to get the fishermen to stop using the methods that they use right now. But they say that is the only way to get the fish. The only reason why they have to use methods like using explosives is because the places have been so over fished. One other thing that others have done is take coral from other places that can afford to miss some coral and put it where it is needed. Now this solution has worked and still does work. For my solution, I think we elaborate on the things that people are already doing and add some other stuff to make it possible. In some parts of the world the coral is doing pretty good on it's own so we should leave them alone unless something starts happening to the coral. I think that the countries that already have had a big loss
