Whether there is any significant impact of the existence of sharks is a non-debatable issue, but two diverse views concerning the issue On the one hand, Sharks are portrayed as vicious creatures who are a threat to human existence, and on the other, what is often overlooked is the vital impact of sharks on our society and the food chain, how it preserves our ecosystem to where it stands today. Consequently, due to corrupt human nature, the population of sharks is declining substantially. This essay will exhibit many arguments, including: the social ,economical, political and environmental impacts of sharks, while favouring their existence and display how corrupt human nature is simply disposing of this valuable creature. Sharks have many positive
The lettuce Coral, Agaricua tenuifolia replaced Aeropora cervicornis in the early 1990’s, at the same time high water temperature in 1998 caused severe bleaching and death of the Agaricua tenuifolia. This left a univocal mark in the fossil records of these uncemented lagoon reefs. (Richard B Aronson et al,
The media chooses to show only the bad side of sharks, so the general population forms biases about these spectacular marine animals. A study on the reputation of sharks, “Sharks Reputation as Man eaters is Unfair” claims that “S[s]ensational television programming such as Discovery Channel’s ‘Shark Week’ imprints certain images in the public’s mind of sharks as deliberate hunters.” Robert Hueter, the director of the Center for Shark Research at the Mote Marine Laboratory in Sarasota, Florida, then goes on to say how Jaws turned sharks from “trash fish” into cold blooded killers. Dr. Hueter then talks about about a simple solution. “Stop describing animals that rarely kill humans as ‘man-eaters’.”
In 2004 in Indonesia a 9.0 earthquake hit and created a tsunami that killed about 250,00 people and the author Richard Lewis recreaded the story in the killing sea because he is interested in the mysterious ocean. First on page 48 the narrator said “for as far as Ruslan could see, meulaboh had become a lake, clogged with floating debris”. this is true because meulaboh was one of the first places that the tsunami hit so all the ocean water was there and went through many cities and destroyed pretty much everything there.throughout the book Ruslan finds dead bodies and so did many of the rebels, it said that on page 49 the narrator said”across the way, ruslan can see dozens of bodies crumpled on second floor stairs of the shopping mall.” because of the tsunami, about 250,000 people had died so there would be many dead bodies everywhere and inside of every building, but especially in the shopping mall because people like to go to the mall so there would be a lot of people there. Then on page 18 the narrator said”from up top came peter exited cry.
All of those species listed are considered threatened by IUCN-World Conservation Union. If these species were to become extinct or endangered there would be an overpopulation of fish in the oceans (Conservationists). In many ways, the Japanese businesses doing these drive hunts are causing many different problems the environment that will eventually come back to haunt the
The cell death leads to the expulsion of the zooxanthellae from the corals, which eventually will lead to coral bleaching. Zooxanthellae give corals their color. Symbiodinium are responsible for the majority of coral’s energy (Berkelmans 2006). A coevolutionary relationship is necessary for coral reefs to thrive. This symbiotic relationship is effective in recycling nutrients and using light (Berkelmans 2006).
Coral bleaching is when the animals that build the coral shed the algae that give them their color and is necessary for survival. Coral bleaching is suspected to happen by two different ways. The first is due to warmer water. The coral needs to be in certain temperature in order to maintain its life. The second way is due to pollution.
Hot tub baths have without a doubt plenty of health benefits. They are very popular these days, but what people do not know is that there are some health risks associated with public hot tubs. Here is more information regarding this subject. Pseudomonas dermatitis
As a result of sharks’ fins and teeth hunting, the number of these animals has significantly decreased. White sharks are often caught in large tuna nets, while hunting on them, or can also get trapped in special complex nettings that protect beaches. The English shark protection organization “Shark Trust” confirms that up to 73 million sharks are killed in targeted hunts for fins annually. Combining all the data worldwide- 200 million sharks are killed around the world each year. This is a great paradox because the number of humans killed by sharks compared to these numbers is insignificant.
On 29th of September 2009, on a Tuesday morning Samoa was struck by a horrible tsunami that was triggered by an earthquake. These natural disaster s caused Samoan citizens to lose loved ones, had their homes stripped away from them along with their crops and how their economic environment was left damaged. This report will be explaining to you how these natural disasters affected Samoa. Earthquakes Earths crust is a hard-outer cover that is surrounding around the whole earth; it is made up of many, many pieces that are called Tectonic plates. These tectonic plates are constantly moving however they move quite slowly, the move up to 5 centre meters per year.
Andy Dehart, Discovery Channel Shark Advisor, spoke about the North Carolina shark over fishing problem. The shark populations on the East Coast were extremely over-fished which lead to the over population of sting rays, a main food-stock for sharks. The stingrays in turn decimated the shellfish populations on the East Coast, leading to calm and shellfish shortages. This shows that sharks are necessary for every eco-system and their destruction affects us in more ways then we can imagine. Sharks are very at-risk for over-fishing because they take a long time to reach the stage where they can reproduce and in general only have a few pups when they give birth.
All the while, millions of dollars are being lost due to a drop in tourism and bans on fishing as red tide wreaks havoc on businesses and marine life. Red tide in Florida is caused by a high concentration of a microorganism called
This hurricane also caused the rails between Miami and New York to shut down and the rerouting of cruise ships. Even as the storm neared Myrtle Beach they evacuated two coastal counties and redirected traffic away from the coasts. The total number of people who evacuated in the eastern seaboard is around
Garling also notes that in 1995 an eight-acre hog waste lagoon in North Carolina burst, and that it spilled 25 million gallons of manure into the New River. “The spill killed about 10 million fish and closed 364,000 acres of coastal wetlands to
If certain organisms lose their protective shells while others become more dominant, the entire food chain system will be thrown off balance for habitants of the ocean and land. I can also use this experiment to show how ocean acidification can also be beneficial for certain organisms to strengthen my rebuttal section. This article will be useful because of its in depth explanation of the experiment and use of primary
