I. REASONS FOR CONCERN ABOUT THE HEALTH OF CORAL REEFS
Coral reefs and the species that dwell in them offer a wide variety of economic and environmental benefits. In 2003, researchers estimated the global economic value of coral reefs to be $29.8 billion. That value stems from the wealth of ecosystem services reefs provide. Whether through tourism or fishing, roughly 30 million people worldwide are “largely dependent on … reefs for their livelihoods.” Reef-related tourism benefits at least 94 countries, 23 of which derive more than 15 percent of their gross domestic product from it. And a “healthy, well-managed reef in the Indian or Pacific Oceans can yield between five and fifteen tons of seafood per square kilometer per year in perpetuity.”
Reefs also provide health and safety benefits. They protect more than 93,000 miles of shoreline in 100 countries and territories from storms and erosion by absorbing wave energy. Furthermore, many reef-dwelling species have tremendous potential for use in pharmaceuticals and other medicines. All told, roughly 850 million people live within 60 miles of coral reefs. According to the World Resources Institute, many of them are likely to derive some benefits from the ecosystem services the reefs provide.
Additionally, coral reefs are a critical environmental resource. Often referred to as the “rainforests of the sea,” reefs are some of the most diverse and productive ecosystems on earth. Reefs are home to a diversity of plant life, providing a wealth of food for fish. As they do with shoreline, reefs shelter marine life from waves and storms. Due to their unique ecological properties, coral reefs “support more species per unit area than any other marine environment.” But these ecosy...

...HGs levels produce two effects that adversely affect reefs. First, warming temperatures raise the temperature of the sea surface as well. Elevated sea surface temperatures cause coral bleaching and can promote the spread of disease. And the ocean absorbs much of the carbon that is emitted in to the atmosphere. This acidifies the ocean water, and the lower pH is harmful to coral. Both phenomena must be checked if coral reefs are to be preserved.
III. EFFECTIVENESS OF THE CURRENT INTERNATIONAL REGIME
There is little doubt that the current international regime is not effectively protecting coral. The statistics speak for themselves. 19 percent of the earth’s coral reefs have already been “seriously degraded or lost.” Over 60% are under “immediate and direct threat.” 90% are expected to be at risk by the 2030s. And by 2050, nearly all coral reefs will be in danger.
Believe it or not the current pop culture surrounding the reef is environmental protection. This mean that people are trying to protect and cleanse the reef of toxic waste and such. And the reason that comes to mind as to why they are protecting the reef is because they would want to preserve such a mythical place from the bottom of their
Earth, an endless source of wonder and beauty, produced the Great Barrier Reef. Hustling and bustling, the Reef thrives like a busy city, teeming with life. Sheltering thousands, corals, maintain the well-being of the Reef; however, the world threatens its nature and delicacy. Populations growing and technological advances increasing, the world becomes more and more disconnected with the natural world, posing an alarming risk for the planet we live on. Although many organizations try to keep the oceans clean, because of human interference and unnatural occurrences, the Great Barrier Reef needs scientific help to adapt corals to new conditions for means of survival, putting pressure on the Australian government to save their ocean environment.
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).
Given how important coral reefs are, the increasingly disappearance of our coral reef ecosystems will continue to have a detrimental impact on marine biodiversity with in these ecosystems. In addition to the decline of the animal species, job opportunities for many staff members that keep our parks open and healthy for everyone to enjoy, revenue be lost due to the decline in coral reefs. To help ensure this downward spiral in eliminated before it is too late, park officials and scientist conduct continuous research on the effects of ocean acidification and global warming on marine organisms and overall health and longevity of these ecosystems. Ultimately, the goal is to develop ways to intervene before it is to late in hopes that we can reverse the damage already inflicted on our coral reefs and allow these ecosystems to re grow once
Some ways to help our coral reefs are conserve water: The less water you use, the less runoff and wastewater will pollute our oceans. Help reduce pollution: Walk, bike or ride the bus. Fossil fuel emissions from cars and industry raise lead to ocean warming which causes mass-bleaching of corals and can lead to widespread destruction of reefs. Research what you put on your lawn: Although you may live thousands of miles from a coral reef ecosystem, these products flow into the water system, pollute the ocean, and can harm coral reefs and marine life. Dispose of your trash properly: Don't leave unwanted fishing lines or nets in the water or on the beach. Any kind of litter pollutes the water and can harm the reef and the fish. Support reef-friendly businesses: Ask the fishing, boating, hotel, aquarium, dive or snorkeling operators how they protect the reef. Be sure they care for the living reef ecosystem and ask if the organization responsible is part of a coral reef ecosystem management effort. Plant a tree: Trees reduce runoff into the oceans. You will also contribute to reversing the warming of our planet and the rising temperatures of our oceans. Practice safe and responsible diving and snorkeling: Do not touch the reef or anchor your boat on the reef. Contact with the coral will damage the delicate coral animals, and anchoring on the reef can kill it, so look for sandy bottom or use moorings if available. Volunteer for a coral reef cleanup: You don't live near a coral reef? Then do what many people do with their vacation: visit a coral reef. Spend an afternoon enjoying the beauty of one of the most diverse ecosystems on the Earth. Contact your government representatives: Demand they take action
Around the world, their are beautiful places called “the seven wonders of the natural world”. These sites are fantastic because of there fascinating views and the fact that they were naturally made, not by humans. One of these seven natural wonders of the natural world is the Great Barrier Reef. The Great Barrier Reef is located off the coast of Queensland, Australia. The Great Barrier Reef was formed by corals growing on submerged islands. The sea level then continued to rise, “leading to more corals growing and forming.” (Zimmerman). The Great Barrier Reef is “a mosaic of 2,900 individual reefs” and can be “seen from space and is not only the world's largest coral reef system but also the largest structure
These man made reefs allow for ecosystems to thrive, if they aren’t already, by providing a strong basis for life that can support the species that live in the reefs. In addition, the manufactured reefs can actually protect and improve their environments and the habitats in them by creating a barrier that has been proven to work. Plus, synthetic reefs ultimately help humans too by boosting tourism and also the economy. “From Balls of Concrete To Habitats for Sea Life” by Naik states that seventy percent of the current natural reefs could die in the next fifty years. Coral reefs help their environments, which help keep the oceans healthy, and if they die out, the balance of nature could be thrown off course. By allowing artificial reefs into the seas and oceans, humans can prevent the disaster of them disappearing in the next few decades. In addition, John Dodrill, a Natural Sciences Manager, told the University of Florida that for every dollar spent on the production of man made reefs in the Florida Panhandle, one hundred thirty-eight dollars was made in return. When thinking about it, creating a manufactured reef isn’t cheap, but making one hundred and thirty-eight dollars for every dollar spent is a superb business deal. Overall, when looking at the impacts an artificial
All over the world coral reefs play an important part in our environment. Not only are the reefs colorful and beautiful to look at but the coral reefs house several different types of fish and other sea creatures. Coral reefs have started to decline over the years due to “climate change, El Nino events, overfishing, pollution and other pressures” (Newnham 1). A healthy coral reef can also collapse due to a natural disaster (Newnham 2). There can be several different reasons why a coral reef has started to decline or has been destroyed.
Oceans cover 71% of the earth’s surface. The talk of climate change can often seem to focus on what is happening in our atmosphere, but there is a lot of change going on in our oceans. The oceans have absorbed 90% of the excess heat and 28% of the carbon pollution generated by human consumption of fossil fuels (Nuccitelli 2015). The purpose of this paper is to show how the effects of climate change effect the coral reefs in our oceans, with a focus on the coral reef systems in the Caribbean and of the Great Barrier Reef. The Caribbean coral reefs are well known to have suffered more damage between the two reef systems. That’s not to say that the Great Barrier Reef has not suffered its own damage. It has and will continue to suffer in the future.
Located in tropical ocean waters, coral reefs provide priceless resources to both human and marine life. The leading natural cause of destruction among the coral reefs is global warming. Other natural causes are earthquakes, hurricanes, cyclones, and typhoons. The destruction to the coral reefs from these natural disasters is minimal compared to the dangers caused by man. Man-made destruction has a much wider impact on the health of the coral reefs. This destruction includes over-fishing, damage from anchors, aquarium industry, overgrowth of seaweed, and being smothered by sediments.
Coral reefs are well known for their colorful array of marvelous sights including a parade of exotic flora and fauna. They are said to be the foundation for a quarter of marine species, and are a crucial support for human life as well. The coral reef ecosystem is a diverse collection of species (ranging from microscopic to larger-than-life in size) that interact with each other and their physical environment. If any piece of a coral reef is harmed or removed the entire community can be seriously affected, even to the point of collapse. Unfortunately, human impact has resulted in long-term stresses that, unlike the short-term stress of natural disasters, coral reefs are not as capable to recover from. “Approximately half of the world’s coral reef ecosystem resources are considered by scientists to be in 'poor' or 'fair' condition and have declined over time due to several anthropogenic threats” (“Status of Corals” par. 2). Through poorly administered commercial practices, carelessness and ignorance among the common people, and human aggravated natural processes coral reef destruction has become a serious issue afflicting the world’s biodiversity and it’s intricate biosphere mechanics (“Human Impact on the Great Barrier Reef” 1) (“What Are Coral Reefs?” 1).
Corals provide shelter for nearly one quarter of all known marine species. The reefs are home to over 4000 species of fish, 700 species of coral, and thousands of other forms of plant and animal life. Living coral reefs are the foundation of marine life, and this also means that they are essential for human life, but all over the world they are dead or dying because people are destroying them at a very fast rate. Already 10% have been lost, and there are predictions that 705 of all corals on the planet will be destroyed in 20 to 40 years unless people stop doing what they are doing now – i.e., pollution, sewage, erosion, cyanide fishing, bad tourism.
In conclusion, I would like to say that before writing this paper, I had no idea how important coral reefs were to the earth. I have learned a lot and I think that if more people were informed about the positive capabilities of them, humans wouldn't be so careless about them.
Today many people do not see the need to preserve corals reefs. Hence because of the lack of appreciation for the reefs, they are slowly disappearing. Many citizens do not realize the importance of these reefs, the species they hold, and the food webs that connect the ecosystems. Our American government has stated many times that they are doing all they can to preserve and to replenish our coral reefs. However, how accurate is that statement? To answer these questions, we first have to understand what a coral reef is and how it can be saved.
