Coral reefs are undeniably important for numerous reasons. They are ecologically important by supporting and providing habitat for marine community, act as wave-breakers to protect the shores from strong currents, generate income for humans and provide many other ecosystem services (Sutton 1985, Demirbilek and Nwogu 2007, Moberg and Folke 1999). Yet, corals reefs around the world are increasingly being destroyed at an unprecedented rate through overfishing, fish-bombing, increasing coastal development as a result of growing human population and others (Munro and Munro, 1994, Grigg and Birkeland 1997, Hoegh-Guldberg et al. 2007). Despite this global phenomenon, our understanding pertaining to how the complex marine ecosystem responds towards …show more content…
(2000) concluded coral cover in Tioman to be in ‘fair’ condition even after the mass coral bleaching in 1998. In addition, Reef Check Malaysia has been actively monitoring reef condition and engaging with community to increase awareness on the importance of coral reef protection (Reef Check Malaysia 2014). As part of their monitoring project, they have been collating information on coral reefs and fishes using various techniques such as belt transects. Brock (1954) first described belt transects and it has been widely used since to assess or quantify coral reef and fish population. This method has been proven to provide approximately similar estimates when compared with other approaches (Samoilys and Carlos 1992). Although it is a fairly simple method, errors and biases are easily introduced and care must be taken to ensure sources of errors are …show more content…
Though both sites in this study were unlikely to suffer from sewage or industrial pollution (“fair” coral coverage) as they are located very far from major cities (effect from nearby settlements are not apparent), indicating that overfishing is more likely to strongly affect the marine ecosystem in the area. Thus, it is pivotal to address the issue of overfishing as removal of key fish species will often lead to physical break-down of the entire coral reef ecosystem (McClanahan, 1995; Roberts, 1995; McClanahan et al., 1996). It is therefore suggested awareness program be conducted with local residents to reduce demand of fish that has a higher value and could contribute much more economically to them through tourism. Stricter enforcements by the government agencies should be practiced to prevent illegal
Introduction: World War 2 was a very significant time in Australia’s history and it was a defining point because it played a large part in shaping the way other countries viewed it. One of these events was the battle of the Coral Sea in 1942. This battle was a triumphant point for the allied forces (Australia and US) as they fought through a number of naval engagements to keep the Japanese from cutting Australia’s supply lines from America. The battle of the Coral Sea was a turning point in the war for multiple reasons such as the major events throughout the battle, the outcome and the measures taken to cause that outcome.
If the climate continues to rise the coral population could become obsolete and disappear (CREARY, M. (2013). One of the most notable climate changes that damaged the coral reefs was the “El Nino” storm in 1998. This storm caused an extreme increase in the water temperature and bleached one- sixth of the corals in the World (El Niño prolongs longest global coral bleaching event. (n.d.)) Although we cannot prevent the weather, humans can reduce the amount of deforestation in rainforests that will reduce the amount of carbon dioxide that is emitted into the atmosphere.
1. It is a scientific fact that biodiversity is greatest near coral reefs and estuaries. But because of human influence coral reefs around the world are dying. Human coastal development, pollution, ocean warming, and ocean acidification are all things that threaten them. The World Research Institute estimated that about ¾ of the worlds shallow reefs are threatened by climate change, pollution, and overfishing.
Twenty of these fragments of coral are to be collected to be tested under different thermal stress conditions. The corals will be placed into tanks in the same amount of depth that they were found in. Ten of the coral fragments will be kept at the initial temperature of the water at time of harvesting and the remaining ten will be put under different temperatures that are higher than thirty degrees
Even as the ocean is warming, much of the coral cover will still remain. We will see a rise in sea-level but to a limited extent. Working to adapting and mitigating to these climate changes will prove successful. Efficient land-based conservation efforts and sanctuary management work will be crucial for facing these climate
Calculations for tourism for the year of 2015 are unavailable at this time, but for the year of 2014, the reef received a total of 2.19 million visitors. It is a well – known piece of information that there is a global climate change going on where there is a rise in CO2 in the atmosphere due to higher emissions of fossil fuel and more deforestation occurring. The ocean then absorbs more of this CO2, which in turn raises the acidity, which in turn creates a poor environment for the coral to live and recover from bleaching that has already occurred. This change in acidity also affects the calcium carbonate that corals use to build themselves. (“Climate Hot Map- Global Warming Effects Around the
With only about one-sixth of the original coral cover left, most Caribbean coral reefs may disappear in the next 20 years. This statistics according to the latest report by the Global Coral Reef Monitoring Network (GCRMN), the International Union for Conservation of Nature (IUCN) and the United Nations Environment Program (UNEP). First of all, as we know nearly two-thirds of coral reefs in the Caribbean are threatened by human activities. For example of human activities that effect the coral reefs are coastal development, watershed-based sediment and pollution, marine based threats and also overfishing. Within the years, the Reefs at Risk Threat Index identified that about one-tenth of Caribbean coral reefs are at very high levels of threat,
The coral was so weak and brittle, with only a little movement of water it withered away into a fine dust of calcium carbonate shells and skeletons. The acidic water wiped out of all the coral to almost extinction. Bothered by what I saw on this trip I headed up to the boat to report my findings to the unesco. The boat ride returning to the mainland I was shocked to find out how much oxygen I used up in my tank, the coral seemed so much farther down than I expected, the sea level insinuate so much higher. Perturbed by this I knew it was all an effect from climate change and we were all to late to correct the damage
The importance of the Great Barrier Reef needs to be recognized due to the rapid increase of the recent mortality rates. After examination of the causes and effects of the Great Barrier Reef destruction, pollution plays the most significant
Oceans are peaceful, majestic, and filled with amazing and vibrant color. A lot of the prostown beauty in oceans can be credited to coral reefs. Lately though, natural coral reefs have been dying for various reasons, and some people believe that artificial reefs can help not only the natural reefs, but other surrounding ecosystems in their environment. Various articles use rhetorical techniques in hopes of enhancing their articles about whether or not artificial reefs are helping or harming the oceans. The first article, “Concern Lingers on Success of Artificial Reefs”, was written by Charles Q. Choi, and for Live Science, looks at both the pro and con side of artificial reefs.
Although the impact on reef fish is still uncertain. It is however, known that reef fish are losing habitats due to the impacts on corals. The wellbeing, reproduction and overall health of fish due to chemical runoff over time, is still being investigated (Amelia S. Wenger, 2015). Research has identified that chemical runoff is increasing nutrient levels in the water. It is believed that this increase in nutrients is connected to the increase in crown of thorns starfish population, which poses another threat to the reef by impacting coral cover (Amelia S. Wenger, 2015).
Have you ever thought what would we be like without fish. How important is our marine life? Over fishing is a huge problem that needs to be brought to an end very quickly. Overfishing is an urgent matter that should not be pushed aside as if it was not as important as the rest. As a result of overfishing, we could lose 90% of ocean fish.
Which places them in a difficult situation, after all some have no intention in harming or worsening the ecosystem all they want to do is supply for their families. In “Sharing the Catch Conserving the Fish” by David Festa, he describes, “Additionally, overfishing has broad ecosystem impacts. For example, bottom trawling, in which boats drag gear and nets along the seafloor, can damage deepwater corals, sponges, and other features” (Festa, 2). The problem is not so much about what we do, but how we do it. Fishermen are not understanding the negative effects the act of overfishing is creating, the equipment being used while fishing is harming the living organisms such as corals and sponges along with many more.
Therefore, the impact of overfishing and illegal collecting of coral may destroyed the social and economic well-being of the coastal communities who depend on fish for their way of life. Beside, it is also direct overexploitation of fish, intertebrates, and algae for food and the aquarium trade, removal of a species or group of species impacting multiple trophic levels, bycatch and mortality of nontarget species, and change from coral to algal dominance due to reduction in herbivores (Reef Resilience Organisation,
In this research paper we will explore more about coral reefs and their importance. Coral reefs are communities of living organisms. They are made up of fishes, plants, and many other creatures. They have been around for millions of years: less than the 0.1% of the world’s ocean floor Is covered by coral reefs, however they grow very slowly, from 0.3 cm to 10 cm per year.
