Introductory
There are more than 2,000 species of coral reefs. But all of them have one problem; coral is in danger of humans. Many species of coral are very sensitive and many things cause them to die (bleach). Reef destruction affects us in the larger world and has solutions to stop coral destruction. The corals’ inhabitants are also in danger from over fishing. Coral is living like you and me (it's made of polyps), so it should be treated like you would want to be treated!
Coral
There are two types of coral: hard coral and soft coral. Hard coral, stony coral, builds reefs and can look like antlers, fingers, brains, domes, and branches. Soft coral can't build reefs and looks like trees, bushes, flowers, nets, or fans. Coral forms 3 known ways: fringing, barrier, and atolls. Fringing reefs are along shorelines. Barrier reefs are separated from shore by water, known as a lagoon. Atolls are rings of shore away from land with a lagoon in the middle. Reefs help shores from being hit by crashing waves. They also have to live in an ocean around the temperature of 73-77 degrees F. They need to be in the fight temperature so the zooxanthellae don't leave the polyps.
Polyps
Polyps do not have neither a brain nor a backbone and live in large colonies. In the large colonies they pass food and messages to one another. When they attach together they are usually on top of dead polyps. Inside polyps are zooxanthellae, which have to live in a specific temperature other wise they leave the polyps and the polyps die. Usually, polyps’ predators are nocturnal like the polyps themselves. The crown-of-thorns starfish is their predator because the starfish devours the polyps and only leaves coral skeletons. Also, the polyps take in calcium carbonate and turn it into a protective limestone cup that the polyps pull into when they feel threatened.
Inhabitants
There are many different species living in coral. Thousands hunt and graze the ocean. With that many fish and hunters they all have to defend their spot in the coral. Those fish include these and many more: yellow tuna, mackerel, and groupers (do not forget there are many more than those three). The inhabitants are usually bright and have good eyesight if diurnal. The fish’s predators are then easier to spot (good eyesight). Some of those predators include snakes and turtles. All colors are changed at night to blend in better. Crepuscular hunters are avoided at all cost. Squid and other bioluminescent fish flash to attract prey. The reason why they glow is because of a flash or glow is created in the fish or squids body.
Causes
Many things done to the environment, like pollution, cause coral destruction. Coral is very sensitive to anything really. Storms, crashing waves, greenhouse effect, water pollution, boat oil leaks, cans, gas leaks, bags of garbage, plastic bottles, fishing nets, chemicals, sewage, dynamite, over fishing, those are just a few causes of damage. The lists go on and on and have just as many effects too. One major cause is over fishing and how the fishermen take the fish. Some drop bombs to stun the fish; some swim down and chase a fish to its home and shoot cyanide into the hole, then they use a crowbar to pry open the coral. Or the fishers may leave the fish homeless by coral mining.
Effects
With all the causes there just about as many effects of coral destruction. Corals bleach when the zooxanthellae leave the polyps. Warmer oceans are also caused by coral destruction. Upset balance of fish is caused when people take too many of one species like in Indonesia groupers are becoming extinct from over fishing. Cyanide kills 90% of the fish and coral cyanide comes in contact with. Coral destruction also affects us in the larger world by keeping the carbon levels down; when there’s no coral the carbon levels raise, mainly in the oceans.
Solution
How can we help save the coral? In Indonesia they banned swimming, passing of small canoes and outrigger boats. Indonesians’ also banned fishing unless with spears or small fishing nets. Indonesia has 24 hr. reef patrol and 'fish aggression devices'. In addition, Indonesians’ started breeding groupers and sea bass. Some coral sanctuaries are made in Indonesia too. Institutions that study dead coral, by cutting the coral open; many believe the more known about coral, the easier to help save it.
Ending Paragraph
Coral is a living thing and needs to be treated that way. It deserves to live and not to be bombed or ripped open with crowbars. Coral has 2 types and forms 3 different ways to form and has thousands of species. Inside coral are polyps, which make coral, living. Polyps are nocturnal like their predator. Coral has many different causes to become bleached. Bleached in other words means dead. Effects like global warming, warmer oceans and many more are caused by coral destruction. Solutions are simple, if we only pay attention to its needs and help protect it. Coral has many bright and colorful inhabitants. Coral takes thousands and millions of years to build and to be created just to be destroyed in two minutes. We should take action to help save the coral.
"Palmyra Island, with its pristine coral reefs and central Pacific location, is a virtual treasure chest of science that has never been fully explored. Scientists at Scripps Institution of Oceanography value Palmyra for its unique, exciting opportunities for scientific research, including a current project that monitors global climate change using Palmyra corals."
