Many tourists travel to different parts of the world today. Most people want to just relax and feel at peace. There are many beautiful beaches available. Being under the hot sun, having a cool drink in one’s hand, and being with your loved ones sounds like the ideal vacation for everybody. People are not aware that one of the reasons why oceans are naturally beautiful is because of coral reefs. Today, many of the coral reef ecosystems are in danger and declining in number. The government and citizens around the world should start taking this seriously because coral reefs provide many benefits to organisms underwater and also to humans.
Most people are not aware that coral reefs are in great danger today. Day by day, more and more coral reefs are suffering from different kind of stressors they experience. In the article “Mass Coral Bleaching in 2012 in the Southern Caribbean” by Jahson Alemu and Ysharda Clement reports that marine pollution, carbon dioxide emissions, overfishing, climate changes, overfishing and dynamite fishing all lead coral reefs to bleach. Coral bleaching is when corals turn completely white (2014). When coral reefs are white, they are considered weak and unhealthy. According to Jashson Alemu and Ysharda Clenement, a mass bleaching took place and caused “up to 85% bleaching and up to 75% mortality of important reef-building species…in Tobago” in 2005 (2014). The result of this mass bleaching should influence government and people to do something about it. Not everyone is informed about this certain problem and people can start spreading the word and make changes in their lifestyles.
Although coral reefs can recover from being bleached, all of them may possibly die as a result of the bleaching. As Neal E. Cantin...

...ormed about coral reefs declining. Businesses and the government can also help out by contributing money to the marine life. Many businesses should build partnerships with other business to donate some of their money. The government should play a stricter role in this. By having governments talk to each other from other countries can make a different. Organizations can also planting mangroves. This will prevent erosions from happening. By uniting as one, they can make a difference and can stop the decline of coral reefs. Having coral reefs around the world protect will benefit both human and nonhuman in the long run. By changing our lifestyle to protect the coral reefs, humans will also be helping out our environment to be green and unpolluted. The food, income, and protection we get from coral reefs are beneficial and without them, it could be a threat to everyone.
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.
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
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 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...
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.
Coral bleaching is when the tiny algae that lives in the coral which causes it to be bright and colourful, gets so stressed out when the water temperature exceeds the limit that it can handle, which then makes the algae
Coral reefs around the world are in danger. One of the causes is global warming, which has been increasing the temperature of the ocean water resulting in coral bleaching. This essay will focus on damage occurring to the Great Barrier Reef.
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).
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.
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.
This website gives a large historical overlook and possible conclusion to the issue of coral reef bleaching. Since the 1980’s episodes of coral reef bleaching and death have occurred almost every year in one or more of the world's tropical or subtropical seas. Bleaching happens in episodes, with the most severe typically accompanying coupled ocean–atmosphere phenomena. Bleaching episodes have resulted in loss of coral
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).
The coral reefs of the world need our help now. You do not have to be a marine biologist to have an effect on the reefs around the world. By simply conserving water, you can help limit the water runoff into the oceans. Limit the amount of emissions put off by vehicles by carpooling or taking a bus. Even though we may live thousands of miles away from a coral reef, we must use caution when adding chemicals to our lawns. Planting a tree not only reduces the amount of water runoff; it also lowers the earth’s temperature. Something as simple as spreading the word can have major
The leading natural cause of destruction among the coral reefs is global warming. Global warming causes the bleaching of coral reefs to occur. Bleaching is a response to stress by the coral reef that happens when the water becomes to warm. The coral then put out a brownish zooxanthelle which causes them to lose their color. Without the zooxanthelle, the corals cannot provide nourishment for itself and th...
Coral Reefs need to be preserved for many reasons. In this paper I will discuss a
