The Bleaching Of Coral And Its Effects On Human Activities

Consisting of less than 1% of the world oceans, the coral reefs are ancient animals comprising of thin calcium carbonate deposits within the photic layer. Aside from its biologically diverse ecosystems, coral reefs are major source of food for millions and provides habitats and nursery areas for many marine organisms. Coral reefs also act as a physical buffer to protect the coastlines from tropical storms and erosion. In addition, many local communities rely on coral reefs to generate an income through activities such as fishing and diving. However, 75% of the coral reefs are under threat from induced impacts of humans and climate change (Burke, et al., 2011). This essay looks at the human impacts constantly being inflicted on coral reefs.

Irreversible destruction is occurring to our coral reef system. The majority of this destruction is caused by the human race. It is important that the people of the world come together to determine how to keep our precious resources in tact for future generations.

The coral reef’s ecosystem are in major threat of the current bleaching events. Coral reefs are the main marine environment, which includes a variety of over 4,000 fish, and 800 different type of hard coral (“Corals”). Over 25 percent of marine animals are supported by the coral environment (“Coral Reefs”). The reefs are a key element of the ocean’s ecosystem (“Coral Reef Destruction”). Water temperatures are estimated to keep rising in the decades to come, which intensifies coral bleaching and other problems like black band disease, and white plague. These illnesses cause a majority of the coral to die, which will then lead to their ecosystem to plummet (“Global Warming”). Research as estimated that one to eight million organisms are yet unknown to scientists

One particularly visible sight that brings climate change to the attention of the public is the series of large tracts of bleached coral on the Great Barrier Reef resulting from unusually warm summers. The Great Barrier Reef is an Australian icon, symbolic of the wealth of Australia's biological diversity. It is the nursery to fishing industries and is visited by thousands of tourists each year, bringing hundreds of millions of dollars into our community. While the high visibility of coral bleaching has made us aware of this impact of climate change we should be equally concerned

Coral reef ecosystems around the globe are threatened by human interferences and climate change. This has led to many scientists conducting studies on global coral reef ecosystems to gain a better understanding of the cause and effects of coral reef damage. In both Hodgson’s (1999) and Carpenter et al.’s (2008) studies, they are aware of the continuous degradation of global coral reef ecosystems. Hodgson's study involved conducting a survey on global coral reef ecosystems to see whether human actions were affecting the health of supposed pristine Coral reefs. Carpenter et al. incorporated Hodgson’s study into a compiled study about the possible extinction of reef building corals due to climate change and anthropogenic effects. Carpenter’s

David Attenborough, a well-known naturalist, introduce us to our modern day “Darwin,” J.E.N. Veron, a former chief scientist whom is the world’s greatest scientific authorities on corals and coral reefs. Veron who has lived and worked on the Great Barrier Reef for most his life has discovered over 20 percent of the known coral species today. And today, he gives us an insight on why the earth’s reefs face a likely mass extinction within the lifespan of the younger generation. During his time as a scientist, he researched particularly on the diversity and evolution of the world’s corals and became aware of their troubles. He then began his studies on the analyses of previous reef extinctions and accrued more evidence of the effects of changing sea levels, temperature stresses, predation by crown of thorns starfish, and human influenced changes in nutrient levels. Veron had witnessed his first patch of coral bleaching off the Great Barrier Reef’s Palm Island in the early 1980s, a tiny clump of white skeleton. Everything started turning white and dies, it was the fast-growing branching corals, but some of the others were horrible to see. After witnessing the mass bleaching, the global damage confirmed a close connection with El Nino weather cycles. By being susceptible to increases in heat and light, corals were alerting scientists to climatic changes. When corals are exposed to temperatures two or three degrees hotter than their evolved maximum, along

Coral reefs have one of the highest biodiversity of animals in one ecosystem than any others on the entire planet. Coral reefs are colorful habitats in the ocean, some of which are not too far from the shore. They are made from skeletons of calcium carbonate and animals, which make a rocky substance known as coral. Coral reefs are a home to many different types of creatures that live under the sea, some are unknown to a majority of the human species. “Coral reefs are sometimes referred to as the ‘rainforest of the sea’ because they teem with life and abound in diversity” (Agardy). Sadly, due to the many factors of global warming, these natural treasures are dying from what is called “bleaching”. Coral bleaching happens from the warming temperature

A group of researchers aimed to quantify regional and global patterns of decline as everyone seemed to know coral reefs were declined but not at what rate. Previous studies gathered qualitative data that was difficult to combine into a comprehensive understanding of what global coral reef patterns are like. They amassed and analyzed data on coral reef cover from 1968-2004 in the Indo-Pacific ocean which has 75% of the world’s coral population. The researchers presented their data with the intention of informing the public to effect better coral management and restoration practices. Their hypothesis was that coral reef decline would occur all over due to the ocean-wide increase in temperature and that it vary between areas depending on nearby

The coral reef of the Bahamas is home to a large variety of different organisms including sponges, fish, anemones, sea stars, and crustaceans. They all use the reef as a form of resource for food, protection from predators, or a place to live (Harborne et al. 2006). However, coral reefs all around the world are in danger of depletion and destruction more now than ever (Richardson 1998). Damage to the coral reef is caused by a number of factors such as increasing temperatures or reduction of sea pH (van Hooidonk et al. 2013). These factors lead to an increase in diseases (Kuta and Richardson 2002; Zvuloni et al. 2009; Patterson et al. 2002; Gil-Agudelo et al. 2004). There is a large range of different diseases affecting a variety of coral species

Whenever someone hear about bleaching, they automatically think about this strong potent chemical used for clothing to make it stain-free, the pungent smell when they open the door to a pool, or when someone plans on dyeing their hair to a lighter color. Bleaching is very useful for humans, but is it good for the environment? Has anyone heard of coral bleaching? Coral bleaching has nothing to do with chemicals at all, in fact it is called coral bleaching because when coral is bleached, it becomes white like when a t-shirt is bleached (though too much bleach can eat a hole). Coral bleaching has been a problem these past few years on the East coast of Australia’s Great Barrier Reef. It has been declining in its beautiful

The increasing population of the Crown of Thorn’s starfish (COTS) is currently a hot topic, especially with regards to the conservation of the Great Barrier Reef. The COTS feeds on the living coral using its hundreds of sucking tubes within its arms, and its eating habits are not sustainable and too much coral is being consumed. This is a major contributor of the decline in coral cover at the Great Barrier Reef (Lucas, 2013). This is one of the main causes of coral cover decline along with cyclones, pollutant discharge from the land, coastal development and climate change affects. (The conservation 2012).

The Great Barrier Reef is one of the 7 natural wonders of the world, the world’s largest coral reef system extends across 2,300 kilometres just off the north-east coast of Australia. The bio-diverse natural reef is the largest living structure on the planet, so big it is visible from space (Great Barrier Reef Foundation, 2017). Unfortunately, the Great Barrier Reef is under threat. There are several elements influencing the rapid decline in the coral ecosystems health. This qualitative study will explore the affects coral bleaching is having on the coral ecosystem of The Great Barrier

Coral reefs are home to more than four thousand species of fish and eight hundred hard coral species and are among the most biologically diverse environments on the planet, being home to thirty-two of the thirty-four phylum known to exist. These critical ecosystems also serve to protect the coastlines from storms, absorbing over ninety percent of force from wind generated waves. Coral reefs also provide economic benefits to coastal cities drawing tourists as well as commercial and recreational fisherman to the area. Across the globe Coral reefs and their surrounding communities are at risk, of sedimentation, eutrophication, toxicity, and coral bleaching due to changes in the environment from agricultural and terrestrial runoff. A wide variety of biogenous and terragenous materials are carried into the river by wind and rain and eventually are emptied into the oceans where they can potentially damage coral reefs.

Coral reefs are unique and diverse underwater marine ecosystems that are found in many parts of the world. Today these tropical reefs suffer a great deal of environmental stresses and are projected to decline over the next century due to global warming. In Grottoli’s article: The cumulative impact of annual coral bleaching can turn some coral species winners into losers, she elaborates on the effects of annual bleaching on three species of coral. Grottoli took three species of coral such as O. Faveolata, P.asreoides P.divaricata and exposed the treatment groups to high temperatures of 31.5 °C for 15 days while control groups remained at a normal temperature of 30.6 °C for the same amount of days. After treatment species were then weighed and

The deterioration of coral reefs is mainly linked to human activities – 88% of coral reefs are threatened through various reasons as
