Are artificial coral reefs beneficial for the marine environment?

Overtime societies all over the world have used artificial coral reefs to embetter the marine environment by using large objects usually made for a different purpose that resemble certain natural reef characteristics. These artificial reefs are man-made underwater structures that are at times done on purpose and most commonly done by accident.1 There are many different kinds of artificial coral reefs, for example, wrecks, such as shipwrecks, sunken cars, bicycles, or oil rigs. Some of these structures are sunk on purpose, others were accidentally left alone underwater forming overtime its own artificial coral reefs forming an artificial habitat for fish and other organisms. …show more content…

Since Australia is an island therefore surrounded by water, underwater attractions, activities, and beaches make up a huge portion in their day to day tourism. Which is also a key factor into their economy. These artificial reefs attract many scuba divers and surfers increasing tourism. Especially since in 2016 according to the World Travel and Tourism Council, “ Travel and Tourism Economic Impact 2017 in Australia”, tourism contributed to about 10.9 percent of Australia’s overall GDP. 3 Australia’s greatest marine attraction is the Great Barrier Reef, which is one of the most popular and largest reefs in in the world, yet due to climate change has lost more than 67 percent of its coral in shallow waters, over the years due to bleaching. Importantly, the Great Barrier Reef is worth 56 billion dollars towards Australia’s economy from its tourism.4 Thus, having a functioning and attracting reef is vital for Australia’s economy. Building artificial reefs rehabilitates all the marine environments lost giving fish and other animals a place to thrive and embetter the already existing natural reefs. Another important factor in Australia, is that these artificial coral reefs act to rehabilitate fish populations promoting marine life. The artificial reefs help aid in creating a natural basis for rejuvenating coral growth. So not only do these artificial reefs help restore marine life lost at …show more content…

Firstly, National Geographic was used to show why artificial reefs were needed and what they use. Thus because they use bamboo modules and tires, the site showed statistical proof how the tires and bamboo modules helped recover many of the lost natural corals. As well as increasing fisheries, a key factor in the Philippines economy, which is why according to National Geographic the Philippines finds artificial coral reefs more beneficial for their marine environment. Although, using these tires, many marine activist sites, have stated that the tires have been known to release toxic chemicals that harm the animal life surrounding. Therefore, doing more harm than good proving the reefs are a disadvantage. There was no statistical evidence but it swayed the audience with an emotional standpoint about how the animals are being

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.

That being said, one would see the importance in preserving the integrity of this structure. Elizabeth Kolbert’s choice to explore the destruction of this massive landmark will surely evoke passion for her subject matter and as a reader had no difficulty depicting her passion. I favor the assumption that other readers will react in a similar manner with the thought that the Great Barrier Reef is in peril. Much of society is only concerned with what affects them personally In chapter seven, she piggybacked with atmospheric scientist Ken Caldeira on One Tree Island to find out learn about ocean acidification and her findings show neither good news nor promise concerning the future of the ocean’s coral reefs. The tone of the chapter is that of death: the balance of coral reef revolves around life and death in its current state.

Cass Sunstein explains in his article, “How Facebook Makes Us Dumber”, the tendency of facebook users to seek out information that confirms what they already believe. He explains the “vicious spiral” that occurs when a homogenous community of facebook users share articles that don’t necessarily have any factual truth. The article confirms whatever bias the community holds, and thus strengthening the belief. Readers of these articles don’t feel the need to fact check or seek out any contradictions of the article because they agree with the article’s content, and because every article that is shared within the community features the same opinion, it becomes as if opposition doesn’t even exist. In Leonard Pitt’s “When ears don’t hear, truth is

In Caribbean, 36 percent coral reefs are located within 2 km of the inhabited land thus this area of coral reefs ecology have highly susceptible to pressures arising from coastal populations. The extensive construction and development for roads, housing, ports and other development has been required to support both of the residential and tourist populations. The coastal development was poorly managed therefore put stress on coral reefs through direct damage from dredging, land reclamation and sand and limestone mining for construction as well as through less direct pressures such as runoff from construction sites and removal of coastal habitat. Besides that, the loss of mangrove and sea grass which filter sediment and nutrients coming from the land has been widespread in the Caribbean which lead to add the pressure towards coral reef ecology. Next, the increased sediment in the coastal waters reduces the amount of light reaching the coral and hinders the ability of their symbiotic algae which is zooxanthellae for photosynthesis.

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

A) Art and Nature in the Northern Renaissance In his letter to Philip Melanchthon (1497-1560) in 1522, Albrecht Dürer (1471-1528) stated that he had begun to see the simplicity of the “native countenance of nature [naturae nativam faciem]” as the ultimate objective of art. I agree with Dürer’s argumentation as the remarks indeed reflect his long-lasting fascination with the depiction of natural forms in art, especially later in his career after two journeys to Italy. Further, I maintain that Dürer’s representation of nature does not lie in mere imitation.

Ok now some random facts about the Great Barrier Reef: Whoever tells you the Great Barrier Reef is being bleached is a liar! The Great Barrier Reef is getting better as you can tell from these photos Look I’ve been studying animals for a long time. And when I mean studying I mean feeding and wrestling, HA HA HA HA From “Studying” these fishes I have concluded that if they didn’t like something they would move; I mean they have the whole coral sea for god sake.

Because this living coral is underwater, its importance to not just the ocean environment, but humans as well, is often hidden. Known as the “rainforest of the sea,” coral reefs are home to 25% of all marine species, Hawaiian reefs alone playing host to over 7,000 known species of plants and animals (Malizia). Not only are the reefs a primary source of tourist recreation and local fishing-- they create the sand on the beaches, determine the size of the waves, and protect the shorelines from storm damage and erosion. In other words, the coral reefs are a crucial resource for Hawaii. In addition, they are a resource in the development of many medical treatments.

Due to global warming the oceans water is heating and killing the coral reefs which is affecting the marine life. Of the coast of many southern hemisphere countries corals have damaged the ecosystem and the life cycle. Over the course of 1 year the reefs have minimized in size by around 30%, so in about 5 years it might not even be here. Throughout the years of the bleaching events people have been fighting to finally get their reefs back to where they should be, but with weather they can not control it has been a little challenging. Overall, coral bleaching is a big issue that needs to be addressed because the biggest living structure in the world might yet to be

This combined with the fact that over the last sixty years coral reefs have seen a decline of over nineteen percent and will lose another twenty percent by 2050 means that any method of restoring coral reefs is worth an appraisal (Feary et al.). There are definitely downsides to artificial coral reefs, however the benefits seem to vastly out way the downsides. One of the benefits of artificial coral reefs is that they can be created purposely in places where there will be low diver impact on them or in places where they will be very beneficial to the environment. They

As observations were conducted on multiple reefs, however, a major decline in the water quality and coral coverage of reefs worldwide had declined dramatically. It was upon these observations that the reefs ability to self sustain was questioned (P. Harris, 2012). Their structure is resilient to most natural disturbances, however, they are extremely vulnerable to human interference such as the nutrient contamination of their water quality that has occurred. The contamination this study focuses on is as a result of fertiliser and other nutrient rich pollution which have contaminated these coral sanctuaries. This contamination has lead to great loss of coral coverage.

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.
