The extinction of the red coral will have a huge impact on economic of certain countries that dependent upon the Corallium rubrum. Besides that, tourism of countries that counting on the beauty of Corallium rubrum to attract tourist would also be affected by the declining rate in Corallium rubrum population. However, the most saddening impact is the loss of habitat towards organisms that depend upon Corallium rubrum as its shelter. Thus, this will eventually affect the balance in aquatic ecosystem which leads to many declining populations of certain organisms in the aquatic ecosystem.
3.1 Impact on Economic
From the economic aspects, the extinction of the Red Coral has the pros and cons. The pros are that it the red coral provide the economic values for the countries. The red and pink coral species (Corallium rubrum) found in the Mediterranean has been used as such for centuries. Of all the deep sea species, red coral represents the largest and most valuable market, with an estimated global trade of 30-50 metric tons per year.
Most of the countries harvest C. Rubrum for economic benefits and traded worldwide as jewellery, home décor objects as well as the curio and aquarium trade (Patty Debenham, Coral In Red). The United States is the largest documented consumer of precious red coral, with 26 million pieces imported between 2001 and 2006 (Patty Debenhem, Coral In Red).
Major exporters of worked precious coral for curios and jewelry include Hong Kong, Korea and Taiwan (The Coral Reef Alliance (CORAL), Mining & Harvesting). Many livelihoods and industries in Italy as well as in Asian countries such as Taiwan and Japan depend on red coral (SeaWeb, Coral Conservation). The countries with the largest catches were Spain (6.9 t...

...itors know nothing of harvesting methods, distribution, and traditional cultural uses of red coral. Hence, an interpretative museum devoted to Mediterranean red coral could be designed to lead the tourist/visitor on their own road of discovery. So, there is a plan by Linda Joyce Forristal to make Mediterranean red coral as an object of marine eco-tourism and cultural heritage with special emphasis on Croatia. To be specific to build a Red Coral Museum. This proposal has been presented during conference organized by Reinventing a Tourism Destination International Conference/ Institute for Tourism on Oct 19, 2002.
The museum of red coral could be an exciting and centre of attraction for the tourist destination that tells the story of Mediterranean red coral, place to centralize Croatian scientific efforts to preserve Corallium rubrum as a viable commercial species.
The Great Barrier Reef is home to a remarkable number of organisms. The coral itself is made up of the skeletons of tiny, flowerlike water animals called polyps, held together by a limestone substance produced by a type of algae. Hundreds...
This article discusses how important the organisms symbiotic with coral reefs are, as well as how important coral reefs are to our environment. Also explained is how natural and non natural things things like hurricanes and overfishing affects them. A study is quoted about how water acidity also plays a role in the bleaching of corals. Lastly, restoration and conservation efforts are discussed and how we could possibly help our oceans.
Coral Reefs are said to be the “tropical rainforest” of the sea. They are home to over 25% of all marine life (http://coralreefalliance.org.stories/storyReader$77). Over the past few decades they have been subjected to destructive anthropogenic practices. Some of the major threats to coral reefs include sedimentation, water pollution, harmful recreational activities, and global warming. All of these things cause stress on corals and can potentially cause mortality. Corals are made up of two parts, a polyp and zooxanthellae. A polyp is a calcerous body that grows from a hard part of the ocean floor. Zooxanthellae is a photosynthetic algae which lives in the polyp and provide energy for themselves and the coral. In many cases, corals undergo “bleaching,” which is a process where corals lose the zooxantheallae or chlorophyll pigment, and turn white (Wilkinson et all). After bleaching corals can survive for several months. It is possible for corals to recover by hosting more zooxantheallae, but it can take between 5 and 50 years for them to recover completely (Wilkinson et all, 1999).
Leading scientists advise climate change will cause increases to the frequency and intensity of extreme weather events. Rising sea levels pose a significant risk to coastal communities, while the world’s oceans could become too acidic to support coral reefs and other calcifying marine organisms. Coral reefs contain only six per cent of the area of the Great Barrier Reef, yet they provide critical habitat and food for numerous species in the ecosystem. However, climate change has already impacted coral reefs in the Great Barrier Reef as corals are very helpless against its potential impacts. Eight mass coral bleaching events has occurred since 1979, triggered by unusually high water temperatures. And because of this, zooxanthellae (photosynthetic algae) leave their tissues and corals will have no more colours hence ‘bleaching’. Without the zooxanthellae, the corals that remain gradually starve to death. Once the coral dies, fish and a multitude of other marine species are soon affected. Rising sea levels and more frequent and intense storm surges will see more erosion of Australia’s coastline, causing community and residential
Imagine a lush underwater place. Beautiful structures colorful animals and places that would never have been thought of before. In reality that's not what it really looks like, really the ocean is a desolate place that is barren like a desert. Many marine species have been lost by as much as 49%.(seeker) A big part of that reason is because of coral bleaching which causes as stated above a decline in species that depend on the coral as there home. Coral bleaching is a serious problem that could cause problems for everyone if we don’t fix it.
In addition to their tremendous ecological benefit, coral reefs are also economically beneficial to humans, as they provide considerable services in terms of tourism, fisheries, and coastline protection. Surveys to determine their total global economic value are imperfect, imprecise, and highly varied in thei...
Coral reefs “form the foundation of all atolls are composed of the skeletons of marine animals which have become fastened onto a rocky substrate in shallow warm water, rich in the calcium used for construction of the skeletons. Most often this attachment is to the skeletons of preceding
Another point explicitly stated in the film was that corals didn’t really have a life expectancy. However, because of climate change, they die early. It was discovered that some corals were turning white after six months which is definitely fatal to our planet because we may witness the eradication of an entire ecosystem in our lifespan as said by Doctor Ruth Gates. In addition to this, there is a big heat wave travelling near the planet which leaves dead corals in its trail and in 25 years, all of the world’s corals wouldn’t be able to keep up with this heat and they will all eventually
The corals use these products to make proteins, fats, and carbohydrates, and produce calcium carbonate. The calcium carbonate is what the coral uses to make its hard skeleton. The coral reefs of the world are of vast importance because they host 25% of all marine life on the planet.
Located in tropical ocean waters, coral reefs provide priceless resources to both human and marine life. They exist in an area about 30 degrees on either side of the equator. Coral reefs are home to more species than any other marine ecosystem. This includes over 1500 types of fish and 500 different types of algae. (Encarta) However, nearly 60% of coral reefs are in serious danger due to both natural and man-made causes.
Coral reefs, which are underwater structures created by calcium carbonate secretions, are some of the richest interdependent ecosystems on Earth. According to Wikipedia, coral reefs occupy less than 0.1% of Earth’s ocean surface, yet they provide a home for 25% of all marine species. Often referred to as the “rainforests of the ocean,” coral reefs are home to thousands upon thousands of species of plants and animals (“Coral Reef”). Not only are they an important part of ocean environments, but coral reefs are also extremely important and beneficial to humans; these reefs protect shorelines and provide countless people with food, jobs, and income sources. However, coral reefs are disappearing at an extremely alarming rate. From overfishing to pollution to sedimentation, the world’s coral reefs are in grave danger and humans must actively work to protect and restore these oceanic rainforests.
The Great Barrier Reef is an exemplary model of the famous exotic coral reef seen in a copy of the National Geographic or the popular animated film Finding Nemo. Located on the coast of Australia, it is known as the “largest biological organism in the world” (“Human Impact on the Great Barrier Reef” par. 1). The idea bears that coral reefs are again not an assortment of organisms functioning separately but rather working together to thrive. The groups of coral that are seen in t...
We need coral reefs, and not just to make the ocean look pretty and colourful, they are more than just that…
Natural has its own world in St. Martin. The island is about two kilometres long and the deep blue water all around it is outstanding to watch. Rocks of different sizes and types are all around the beach, some of which are with razor sharp spikes that can cut your foot into pieces if you step on them. Moreover, different coloured sea weeds and live corals can be seen on the rocks which are submerged in the water. St. Martin is the only Island in the world with live corals. There are more than thousands of different types of coral in this island. Scientists say that this island actually grew from this coral by the metamorphosis of different c...
