Coral Bleaching And Its Effects On The Great Barrier Reefs

Improved Essays
Coral reefs aren't only beautiful, they're also extremely important to our ecosystem. Yet we hardly hear about their benefits, or even the fact that the worst coral bleaching event ever recorded on the Great Barrier Reef started in 2014 and officially lasted until about 6 months ago. Only about 7% of the reef just on the southern side was left unbleached & alive at it's worst point.(ABC) Overall about 12% of the worlds reefs were affected by this massive bleaching event. These recent events have been linked to climate change and is in several ways proved to be caused by humans.(NatGeo) The ocean has soaked up about 93% of the heat from climate change, making them significantly warmer than they were just 50 years ago.(N.O.A.A.)(Q.C.I.Q)(U.O.Q)(T.O.A) Significant reef degradation has occurred in 93 out of the 109 countries they can be found in.

What is Coral Bleaching and why should you care about it? Coral bleaching occurs when the coral get stressed this can be due to change in temperature, light, or nutrients. Through expulsion or loss of algal pigmentation this turns them completely white.(NOAA) Coral bleaching events have happened several times during the past, but have never been as severe as the 2014-2016 event; not only effecting the Great Barrier Reef but reefs worldwide.(A.I.M.S.)(N.O.A.A.)(U.O.Q)

Even if you don't live near a reef you can contribute to their protection. You can become an advocate, take it upon yourself to learn about laws, and spread the word about ways to help. There are several organizations that you can join who's main goal is to protect coral. Protest against threats like over-fishing, pollution, or waste being dumped into the oceans. Simply living a more sustainable life can make a difference; conserve energy and pay attention to your carbon footprint. Following the reduce, reuse, recycle rule can make a more significant difference than you would

    When the corals' health are in jeopardy, the health and overall well being of all the organisms that rely on them are at risk as well. Many organisms, along with their babies and eggs, will be exposed to predators if they do not have healthy coral reefs to depend on for shelter. Predators will have easier access to their prey if they are ever without a home, and this will result in a decline in population of the consumers lower in the trophic levels (little fish are wiped out, and predators overpopulate). If there were ever a decline in the prey population, all of the organisms higher up in the food chain would be killed off as well, since there wouldn't be enough food to keep the higher trophic levels healthy and…

    In 1980, global warming caused 80% of the Indian ocean corals to become bleached, about 20% of them died. If the temperature even 2 degrees above the normal maximum for that time of year it will cause bleaching. Light too much or too little, is another stressor for coral bleaching. Global warming is not the biggest threat to coral bleaching, it’s the rising acidity levels in the ocean. the rise of acidity in the oceans has been connected to the increased levels of carbon dioxide.…

    When a coral is bleached, this does not mean that a coral is dead; but it does mean that are more subject to dying. In fact, if the bleaching is not too severe, coral have been known to recover. However, if the loss of the zooanthallae is prolonged, causing the stress to continue on, the coral will eventually die. The factors that cause corals to go into stress is not just the warming of water, but can also be too cold of a temperature. For example, when water temperatures dropped 12.06 degrees Fahrenheit lower than the typical temperatures in the Florida Keys, it caused a coral bleaching even that resulted in some coral death (“What is coral bleaching?”).…

    “We should preserve every scrap of biodiversity as priceless while we learn to use it and come to understand what it means to humanity” (Edward Owen Wilson, 2006). The Great Barrier Reef (GBR) was inscribed on the World Heritage List in 1981 and stretches for more than 2300 kilometres along the northeast coast of Australia, including an area of about 347 800 square kilometres of seabed. It is the largest coral reef ecosystem in the world with 2500 coral reefs and is home to more than 1500 species of fish and 5000 species of mollusc. Approximately 215 species of birds are found on its islands and cays. Despite the GBR being given World Heritage status the health of the GBR has declined to date.…

    “Runoff carries nutrients sediments, and pollution from land-based sources and deposits them directly onto our reefs.(http://wwf.panda.org/).” Too many nutrients create algal growth creating a decrease in oxygen levels leading to the condition, Eutrophication. Erosion by construction, inland or along coasts, mining, logging and farming increases sediment in rivers. This then ends up in the ocean where it smothers corals by trapping them from the light which is needed to survive. Sedimentation limits the light ability to the corals inhibiting their ability to feed and reproduce.…

    It is also a breeding ground for animals such as six different species of turtles. The great the barrier reef is ancient and to some is dated back to around twenty million years ago. Sadly the great barrier reef is threatened by many things such as climate change, warmer ocean temperatures put stress on coral and lead to coral bleaching. The great barrier reef has experienced two mass coral bleaching events in 1998 and 2002, the bleaching was more severe in 2002, when aerial surveys showed that over more than 50% of the reef experienced coral bleaching. Sediment, nutrient and agriculture pesticide pollution from river catchment runoff is also affecting the reefs health.…

    Climate change is the greatest global threat to the coral reefs. Mass floral bleaching events and infectious disease outbreaks are happening more often now that the temperatures are rising across the reefs' water, the pH of the water is decreased. This causes the reduction of calcification rates in reef building organisms. Both climate change, and carbon dioxide contribute to these mass bleaching…

    When coral reefs disappear it will cause a chain reaction affecting people all over the world. "We are seeing an overall negative impact from ocean acidification directly on organisms and on some key ecosystems that help provide food for billions. We need to start thinking about the risk to food security" (CNN World). People don’t understand the severity of what we are doing to the ocean and the world. If no action is taken and we continue on with our daily lives not caring about the long term effects of our actions then it could wipe out entire ecosystems or entire populations of sea…

    We as humans have over 58% to do with the destruction of the coral reef, and we don’t fully understand the importance of the coral reefs and what they do for the marine life and the ecosystem as a whole. The Great Barrier Reef that was pronounced dead was a complete eye-opener to the whole coral bleaching situation that is occurring all over the world. We as a nation need to come together to educate each other on this issue because although the coral reefs are only 1% of earth’s ecosystems it will have a huge effect on our everyday life. Little by little if we take steps to protecting our reef’s they’ll no longer be in danger and continue to thrive in our…

    Coral Endangerment and Carbon Emissions Robert Swan once said, “The greatest threat to our planet is the belief that someone else will save it.” It is well known that when it comes to the environment, human and destruction are synonymous. Simply look up “coral” in a search engine and you are bound to find countless articles showing how our excessive release of carbon has jeopardized reefs around the world. Yet most people, after concluding the article, still do not have the full sense of what is actually happening. In this essay I plan to address how human efforts are helping coral reef communities achieve resilience in response to the increase of human carbon emissions.…
