Environmental Effects Of Coral Bleaching

Improved Essays
Half the coral in the Northern barrier sea are dead due to coral bleaching. Coral bleaching is “When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white”. Now most people may think nothing of that fact. But the reason the coral died due to turning white is to due to the algae leaving the coral’s tissue. The coral and the algae have a “symbiotic relationship with microscopic algae called zooxanthellae that live in their tissues. These algae are the coral’s primary food source and give them their color” (What). When the algae leave the coral, the coral is left vulnerable and if left that way long enough, the coral …show more content…
Then as the coral started to die due to an increase in temperature in the water, it was observed that the water began to become cloudy because “As the corals die, the release great quantities of mucous into the surrounding water, making it appear increasingly cloudy“ (Coral Bleaching). These conditions create an environment suitable for bacteria and fungi growth.
It is 2016 and as of now “the latest global coral reef assessment estimates that 19 percent of the world 's coral reefs are dead.” (Block). According to a graph shown (free) the trend for coral bleaching is not looking good. If this trend continues the possibility of the coral reefs demise does not seem to be too far off.
The disappearance of the coral reefs are not certain, but scientists are speculating that the disappearance of coral reefs may result in the disruption of the food chain. But they are certain that “The ocean fishing industry, which employs 38 million people worldwide, would collapse. Caribbean island nations that depend on tourism dollars would see those disappear.”(Kirkpatrick). If the coral reefs disappeared then the overall health of people around the world would diminish because coral is used in

    “We're seeing areas that have seen high temperatures for two to three years in a row. There's no time for corals to recover.” (Weisberger). This is a direct result of global warming. If there is not a drop in the temperature, there is a great chance that the coral will never recover and it will be lost forever.…

    Growing up in the Florida Keys, I have been surrounded by the ocean my entire life and have personally witnessed it gradually get destroyed over the years. Because of tourism playing a huge role in the Florida keys, our beaches and oceans are left polluted and leaving our reefs to extinction. Not only in the Keys, but throughout Florida our waters are heavily polluted by the great amount of tourism in our state. In the Florida Keys and the Caribbean, there has been a vast decline in staghorn and elkhorn corals leaving the reefs scattered since the 70’s. As I continued to observe and research this topic, I noticed that humans overlook the effects that they cause and focus on the benefits they receive.…

    Coral reefs provide shelter and food for more than 1 million plant and animal species, which is nearly one quarter of all known marine species. This number includes over 4,000 species of fish, 700 species of coral, and thousands of other plant and animal forms of life (Cesar, et al.). A single coral reef at its prime contains tens of thousands of species, housing some of the most dense and diverse communities of vertebrate animals in the world. Unfortunately, with the destruction that they face, very few coral reefs still resemble this condition, with corals and fishes less abundant than they were a few decades ago. Since we didn’t start studying coral reefs until they were already degrading, we aren’t sure about the historical biological baseline…

    Elizabeth Kolbert’s book, The Sixth Extinction, covers the argument that we are currently in another mass extinction because the Earth is following similar trends as it did in the past five mass extinctions. The first chapter of The Sixth Extinction starts out by discussing frogs. Frogs are the one of the oldest species on Earth; however, the extinction rates of frogs is higher than it’s ever been, and it’s only increasing. Kolbert then focused specifically on Panamanian golden frogs. Not too long ago, these frogs were plentiful, but recently the numbers have decreased due to human’s introducing a native species to Panama: Chytrid fungus.…

    Over many years hard coral polyps form reef structures that support a variety of marine life, these corals also known as reef-building corals found within the Great Barrier Reef include brain coral, staghorn coral and branching coral. In the tissues of these corals algae called Zooxanthellae live and provide the coral with important nutrients, while the coral provides the algae with a protected environment (National Oceanic and Atmospheric Administration, 2017).

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…
