10/27/04 Research in the Disciplines First Paper Final Draft Tragedy of the commons invading our environmental rights: Case study Coral Reefs In our world there are many resources, all of which people do not have a choice in sharing such as our air and our oceans. These resources are looked at as infinite, although this is not actually the case. Each time one person does something to pollute or use these types of resources, it affects the whole of society. This is the idea of the tragedy of the commons. This tragedy is the phenomena in which a resource may be used to such an extent that it is ruined for all. An example of this tragedy is given in the following scenario: given an open pasture as a commons to which all the herdsmen have a stake; each one will try and keep as many animals on the commons as possible. By adding one more animal to his herd, an individual gains a positive to himself but the negative effect of over grazing is felt throughout the commons. The effect, of overgrazing by one additional animal appears minimal so the other rational herdsmen conclude to add an additional animal to their own herd. Since all the herdsmen are thought to be rational this conclusion is reached by each of them. The effect of, overgrazing will become detrimental to the pasture and all the animals will die. There in is the tragedy because of peoples’ greed to use and or need of a limited resource the over use or degradation of it leads to its destruction. The destruction of these resources leads into another topic discussed by Shari C... ... middle of paper ... ...and Max L.

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.

The tragedy of the commons is a very unfortunate and very real thing. It occurs whenever everyone takes a little bit of a limited resource repeatedly. The result of this is that all the resources are gone. In The Lorax, the Once-ler cuts down all the truffula trees in the area to make thneeds (The Lorax). When all the trees are gone, the business shuts down and all the animals are forced to leave (The Lorax). The factories polluted the air and made the area unsafe to live in (The Lorax). This is a perfect example of a tragedy of the commons. A similar event happened in Easter Island. Tribes started inhabiting the area and began using the trees to build houses and eat food from them (Easter Island). Eventually all the trees are gone, and the society resorted to cannibalism and war because there was no food (Easter Island). Garrett Hardin states in his essay that maximimizing population does not maximize goods (Hardin). In this essay, both tragedies of the commons will be compared and will be examined to see how they could have been prevented.
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
In Part I, Moral Problems, Greene relates Hardin’s “Tragedy of the Commons” to compare individualistic and collectivistic interests. In the “Tragedy of the Commons”, a single group of herders shares a hypothetical common pasture. Hardin posits that, were everyone to act for his or her individual self-interests, the pasture would be eroded and nothing would be left (19). Collective interests should triumph over individual interests whenever possible (24).
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
Bleaching is when the ocean water become too warm, “corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This is called coral bleaching. When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality.” (Cave and Gillis). When a coral bleaches, it is more of like a self defense mode, which makes it turn white. The coral loses its food source as well. The downfall of this is that without the cooler waters, the corals could die of starvation or disease. Cooler waters from below can help a bleached coral bounce back to its natural state. However, if the water stays too warm for an extended period of time, “the corals don't just bleach, they cook and they die very quickly,.” (Westcott). Throughout time, much of the corals near Cairns and northward have lost the most corals. Hughes states that, “near Cairns, the Great Barrier Reef has lost 47 percent to 83 percent of their coral and as you go northward, the Great Barrier Reef has lost 11percent to 35 percent of its corals.” (Cave and Gillis). In another report, “a study last year found the largest die off of corals ever recorded with about 67 per cent of shallow water coral found dead in a survey of a 700km stretch.” (Johnston). In 2016 and 2017, there were back to back bleaching events. According to CNN reports, “back to back bleaching events in 2016 and 2017 have devastated a 1,500 km (900 miles) stretch of the UNESCO World Heritage Site.” (Westcott). Before the 2016 bleaching event of the Great Barrier Reef, there have only been two bleaching events, 1998 and 2002. According the Hughes, “only 9 percent of the reef has avoided bleaching since 1998.” (Cave and Gillis). That means that over 90 percent of the Great Barrier Reef has been affected by coral bleaching at least once in the past 19 years.
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.
Climate change has been affecting coral reefs in a negative way. If the climate continues to get warmer more of our coral reef become bleached, the structure of the reefs will become weak, and algae that keeps coral healthy will die. In the essay, “A framework for understanding Climate change impacts on Coral Reefs” by Joshua Clinner (2016), he emphasizes our climate change has become one of the long-term threats to coral reef. The article “Climate change and human impacts are damaging the world’s coral reefs”, which didn’t include an author (2001), states that the sea temperatures throughout the tropics has increased dramatically leaving much of the coral unhealthy. Spencer Hall (2008), discussed in his article “Coral Reefs and Climate Change”, how the increase in climate change puts a lot of stress on coral reefs because they are very sensitive to the change of temperature. Rigel B (2003) states in his essay, “Climate Change and Coral Reefs”, that coral reef has already been negatively impacted by
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 Tragedy of the Commons “is a problem that occurs when individuals exploit a shared resource to the extent that demand overwhelms supply and the resource becomes unavailable to some or all” (Wigmore, 2013, August). He explains if by using an example of herdsman caring for their cattle in a common land owned by others. Everyone in the land have the same number of cattle they are allowed to have. If one herdsman was being self-centered things and had more cattle because he was thinking of his needs would then damage the community by “overloading it, erosion set in, weeds take over, and he loses the use of the pasture. He would just worry about his goals now and not the overall outcome which not only affected him, but the other herdsmen as well. (Hardin, 1974,
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.
Coral Reefs need to be preserved for many reasons. In this paper I will discuss a
