Preaching Against Coral Bleaching

Known as paradise around the world, Hawaii is also a graveyard of coral. Covering one percent of the Earth’s surface, coral reefs are slowly decreasing as a result of bleaching. According to KITV4’s recent report about coral bleaching in Hawaii, “75 percent of the corals surveyed in Lanikai, Waimanalo, Kaneohe and Hanauma were dead or dying” (qtd. in Moser 00:35). Over twenty-five percent of innocent sea animals lose their home when the coral reef is destroyed. Human activity clout the growth of the coral reef. A home for sea animals and a barrier that protects Hawaii’s shoreline, coral reefs are critical to marine life, and without awareness and immediate action, the Great Barrier Reef will cease to exist.
The coral reef ecosystem relies on other living creatures to survive. Coral reef obtains beautiful colors from microscopic organisms called algae. The algae supplies the coral with nutrients and oxygen to support the coral’s structure. Meanwhile the coral provides the algae with carbon dioxide to perform photosynthesis. Their survival depends on their cooperation with one another; an example of symbiosis. However, when the coral is stressed by its environment, the process of bleaching begins. For example, if the temperature of the water rises, the algae quickly evacuate from the coral, stripping it of all its nutrients. Exposed and vulnerable, the coral slowly loses its beautiful colors and becomes pale white. The symbiosis between the coral and the algae is disrupted. “Without the algae, the coral loses its major source of food,” (“Coral Bleaching?” para 1) and drained of its resources, the damaged coral , “... is more susceptible to diseases” (1). If conditions are prolonged, the coral ev...

...ral reef, but it is also securing a safer place for future generations. Our actions today affect the world tomorrow.
There is no such thing as action without consequences. Although the ocean is a powerful entity, it cannot be taken for granted. By taking measures to minimize the greenhouse effect, we can help the ocean to maintain the pH level and moderate sea temperature that is conducive to the health of algae. In turn the algae will support the growth of the coral reef. The coral reef provides Hawaii with not only its beauty, but also its resources; affecting “highly diverse populations of marine plants, invertebrates, fish, sea turtles, and marine mammals” (Lee 1). If human were to act immediately then we could also have a symbiotic relationship with the coral reef. After all, it is our responsibility to protect this most precious gift - the great barrier reef.

Coral Bleaching : Causes And Effects Essays

- Coral bleaching can be caused when coral is stressed by many things including pollution, overexposure to sunlight and extreme low tides however, it primarily occurs when corals are stressed due to unusually high sea temperatures (National Oceanic and Atmospheric Administration, 2015). Unusually high temperatures cause coral 's colourful, symbiotic algae (zooxanthellae) to separate from the coral leaving it to appear white (De 'ath, Fabricius, Sweatman & Puotinen, 2012; Baker, Glynn & Riegl, 2008)....   [tags: Coral reef, Coral, Climate change]

Essay about Bleaching of Coral is Harming the Environment

- ... Although some coral reefs may retain their physical structure, most still lose some of their framework due to physical disturbances (Coker, Pratchett and Munday). However, with coral bleaching threatening fish habitats, the larger the risk of extinction for these and other species will be. Therefore social hierarchies in the aquatic environment will change. This concludes that live corals are important for fish species than just a structure (Coker, Pratchett and Munday). In the Effects of coral bleaching, induced bleaching was performed by placing two colonies A....   [tags: color, global warming, environment]

Coral Bleaching: Potential Mechanisms and Observed Adaptations Essay

- Coral Bleaching: Potential Mechanisms and Observed Adaptations Coral reefs are the most biologically diverse marine ecosystems. Driving this diversity are cnidarian corals which are obligate mutualistic symbioses between coral animals and dinoflagellate algae of the genus symbiodinium. These algae are commonly called zooxanthellae. This symbiosis between heterotrophic hosts and photosynthetic symbionts allows coral to thrive in nutrient poor seas and deposit calcium carbonate to build reefs (Toller et al....   [tags: Sea Coral Corals Ecosystem Papers]

- Imagine yourself observing one of the most diverse ecosystems on earth. Thousands of species of plants and animals provide a dizzying array of color and motion. Massive structures provide a canopy that shelters hundreds of exotic species in a myriad of microclimates. As land-based observers, we almost automatically assume that this is a description of the rich ecosystem of a tropical rainforest. However, if we take ourselves off the safety of dry land and immerse ourselves in the ocean, we will find an equally dynamic environment in the depths of our world’s coral reefs....   [tags: essays research papers fc]

Essay on Coral Bleaching

- Coral Bleaching Coral reefs are the most biodiverse ecosystem on the planet. There are more than 25,000 known species of organisms and countless others that have yet to be identified (Helvarg, 2000). Reefs thrive on the shallow edge of tropical seas, most often on the eastern edge of continents along warm water currents that brush the coasts. Reefs cannot live in cold waters and are limited by ocean depth and available sunlight. Coral is the foundation of the reef community, providing a three-dimensional structure where thousands of species of vertebrates and invertebrates live and feed....   [tags: Papers]

Essay on Bleaching Away the Beauty of Coral Reefs

- Pretend you are about to go scuba diving in the ocean. You jump in the water and begin to sink down. As you start surveying the coral reefs around you, something catches your eye. The coral has turned white, and no longer moves with life. This whiteness seems to have spread over a large area of the reef. You no longer see the colorful branches swaying in the current, or the schools of tropical fish swimming through the leaves. This death-ridden reef will never have the same life it once had. This phenomenon is known as coral reef bleaching....   [tags: essays research papers fc]
