The oceans span across vast amounts of Earth and they being impacted by human disturbance. Due to the oceans being an open resource, many tragedy of the common problems are occurring. Among the problems, overharvesting is a notable one, specifically the decline in sharks due to shark finning. Only the fins of the shark is harvested in shark finning, the still-live leftover body is discarded back into the ocean to die of blood loss, suffocation, or predation (Wigginton, 2014). Between 2000 to 2010 it was estimated that between 100 million to 273 million sharks were harvested annually (Worm et al. 2013). This is a huge issue in regards to ocean dynamics. Since sharks are apex predators, their removal can cause a shift in the food chain causing cascading effects down to the marine floor.
Seeing that shark finning is such a large industry,

2013). Oceana (2016) estimated that there is a $314 million USD industry from shark watchers. This means that there is a large ecotourism industry that uses the intrinsic values of sharks that can challenge the instrumental value of the sharks.
My perspective:
My perspective on this industry coincides most closely with the environmental groups with a splash of cultural connections. Sharks should not be harvested for their fins alone, the industry is not large enough for it be supported. There are alternatives that could be used instead of shark fin. Shark fins are know to be tasteless and are eaten for their gelatinous texture, meaning it could be substituted for something else.
In a food experiment, chef Corey Lee created a faux shark fin soup using hydrocolloids to simulate the same gelatinous texture shark fins have (Goodyear, 2011) .This shows that there are alternatives to the product. A quick google search for ‘ shark fin alternatives’ give you recipe options for using vermicelli noodles or other gelatin
Sharks have also been subjected to medical research, games and competitions, jewellery, souvenirs and cosmetics. We need to take into consideration that sharks play a vital role in the natural world that we live in. it is imperative that we look after these majestic creatures and ensure they remain protected. We need to be aware of the dangers of sharks, swim in protected areas where there are shark nets, and do not swim after dark in the sea (especially not alone) as the sea is the sharks home. Humans should also be wearing wet suits as protection in the ocean. The sea is where they live, they swim freely and they eat – they do not particularly target humans but rather prey on food that is available to them in their habitat.
So why do we need sharks? Well, Sharks help keep the ocean healthy and clean for over 450 million years. They also help remove half of the worlds green house gases and produces oxygen more than all of the rainforest's combined! Sharks are just as important as all the trees in the world because they have one thing in common, provide us with oxygen. Without the sharks help we wouldn't be able to get rid as much of the greenhouse gases as we want to, which means global warming would have a lower rate of happening faster. Most importantly they provide us with food. How? They would usually eat the old, sick or slower fish in the population of the ocean to the right size so the prey species don't cause harm to ecosystem by becoming to populated. They are also at the top of the food web. If all the sharks went extinct the entire food web would collapse causing many other species of fish to disappear. So instead of killing the sharks, we could lure them away to somewhere else. As they have a huge impact to the environment.
As they are at the top of the food chain, sharks play a very important role in the oceans in a way that an average fish does not. Sharks keep populations of other fish healthy and in proper proportion for their ecosystem. By preying on the old, sick or slower fish in a population, they prevent the spread of disease and prevent outbreaks that could be devastating. According to Ransom Myers from Shark savers, “sharks may be gone within the next decades if we continue to kill them, resulting in the loss of important foods that we depend on for survival, causing a marine ecosystem imbalance.” At the same time, I accept that shark nets could be useful, especially in shark infested areas that have been renowned as spots where many attacks have occurred, but I still believe, as you would, that scientists should spend more resources on working out why it is becoming more common for sharks to be entering shallower waters, looking for food – namely seals, who just happen to look like
One of the governments main reasons for culling the sharks is because they are coming in too close to the shores and becoming a potential threat to swimmers. But why is this happening? This is due to a change in shark feeding habits, but because they are eating more human of course not! Rather because us humans are over fishing and eliminating the fish/food sources of which sharks normally feed on. This is forcing sharks to come in closer to find food. Us as humans have forced sharks to come in closer and are now killing sharks because of our a...
The bull shark may be responsible for many shark attacks in the world but I believe that we have no right to kill them. Sharks are very important to animals food cycles and if the food cycles get messed up it can greatly effect the world. In fact, the bull shark is more vulnerable to human impact due to their ability to live in fresh and salt water but many sharks that are killed are for either shark fin soup or their liver oil. The sharks liver oil has many uses now but it started as a machine lubricant. Another way that sharks die is by recreational fishing. The sharks can get caught up in the fishermen's nets and eventually suffocate and die. As an environmental community, I feel like we need to inform people about shark habits and how to keep sharks safe. The water is their home and we are
Information (sub-point): The solution to the problem of shark finning is to sign petitions and force the government to pass legislature that will ban shark finning, as well as ban the import of shark fins. In 2000, Bill Clinton signed the Shark Finning Prohibition Act of 2000 (SFPA), which “banned finning on any fishing vessel within United States territorial waters, and on all U.S.-flagged fishing vessels in international waters” (Speigel, 2011). Currently, it is also illegal to hunt sharks in many parts around the world due to various restrictions set by other government, but it is not illegal to import and sell shark fins. Finding shark fins in the US can be as easy as walking into an Asian restaurant and ordering shark fin soup. If we truly want to make a difference, and see a rise in the shark populations around the world, we need to ban the sell and trade of shark fins
Sharks have been on this earth for nearly 450 billion years. To put that into perspective, the first modern humans date back to about 60,000 years ago ("Our Mission: To save Sharks and Mantas”). Since then, both humans and sharks have evolved into the predatory mammals they are today. However, with the quick development of humans, civilization and technology, humans have not been able to fully understand the ways of sharks, although the motives of other human celebrities have been easy to understand and decipher. Because shark attacks have been becoming more televised, and sharks have been known to be more of a “threat” to humans, shark research foundations, such as the Shark Research Institute and the Pelagic Shark Research Foundation, have been created to help give an understanding to these creatures. Over 100 million sharks are being killed each year, and there is a counter on the Bite-Back Shark and Marine Conservation website. As one spends more time on the home page, the number on the counter is constantly increasing, showing how many sharks are slaughtered in the year to come (“Bite-Back – Shark and Marine Conservation”). Even with research to show that sharks are valuable to the ocean and vulnerable, there are people that think otherwise (“The Pelagic Shark ...
Sharks are the apex predators of the ocean, meaning they regulate the marine food web. The ocean (there is only one, not 7) covers between 70 – 75% of the earth’s surface and houses 80 – 90% of all life on earth, yet sharks role in maintaining the ocean is often overlooked. The main reas...
Every year, there are about 100 million Sharks killed, ultimately for its commercial success. Their fins are used as the main ingredient for a dish so-called Shark soup. However, many are unaware of the actual importance of Sharks' existence on Earth. They do a number of things to control and balance aquatic life down below, which in return affects how we live on the surface. Sharks have existed in our world for over 400 million years, if they were to suddenly disappear for industrial purposes, much problems will be encountered throughout the world. We must preserve the lives of Sharks, for many reasons most importantly that shark hunting is morally wrong, it may provide economic failure in a given time, and it may serve a critical unbalance of a healthy environmental state.
Shark slaughter has led to shark populations being rapidly decimated all around the globe. Fishermen report that sharks are also getting smaller because they are not being given enough time to fully mature. Although there are other fish that are targeted more than sharks, they are not exactly affected by the kind of endangerment that sharks are currently experiencin...
In 2015 only 59 shark attacks have occurred around the world compared to the millions of sharks killed by humans every year. Due to these accidental shark attacks people tend to think that sharks, especially Great Whites are evil creatures with malice intentions when attacks do occur; but, on the contrary that is wrong. Sharks are not the only beautiful and unique creatures in the ocean, they also play a vital role in our ecosystem; however, due to human interference they might not be around much longer, through awareness sharks can be protected from endangerment.
When most people hear the word "shark", the image of a vicious killing machine pops into their head. They picture something out of the movie Jaws, where a massive Great White shark terrorizes an entire beach and eats dozens of people. However, this fictional story is nothing more than Hollywood entertainment. In the real world, the tables are turned. Humans are the ones who kill sharks, and not just by the dozens. It has been estimated that over 100 million sharks are killed every year by humans (http://www.iflscience.com). Some estimates claim that the actual number of sharks killed every year could be as high as 273 million (http://www.iflscience.com). In this research paper, I will inform you of the many ways that sharks are being killed,
Thesis: Sharks should be conserved because they are an important part of the ocean, attacks are often incidental, and human behavior influences the behavior of sharks.
Oceans are such so vast that people underestimate the impact their actions —seeming so insignificant— have on them. Humans have by and large taken the oceans for granted; not considering how important a healthy ocean is to our survival. A popular mind-set is that the oceans are a bottomless supply of fish, natural resources, and an infinite waste dump. There are myriad reasons why the oceans should be saved and the most obvious one is marine life. With 71% of the Earth being covered by water, it is obvious that sea creatures are predominant form of life, making up 80% of the species of life on Earth. However, as important as marine life is, that is not the only reason why saving the oceans is crucial. The ocean floor provides natural resources such as, oil, natural gas, petroleum, minerals, medications, and ingredients for foods and products. The economic benefits of the oceans are huge and significant, as well. Fishing and fish products have provided employment to 38 million people and have generated about $124 billion in economic benefits. However, oceans are on the verge of crisis, marine life, natural resources, transportation, the economy, and important ingredients are at risk due to overfishing, pollution, and acidification. Thus, in this essay I will argue that, oceans are not impervious to human activity and threatening the health of the ocean threatens the health of humanity, since oceans key to our survival.
Did you know that more than 90 percent of all organisms that have ever lived on Earth are extinct? According to Pandey, the author of Humans Pushing Marine Life toward ‘Major Extinction’, nearly 10,000 species go extinct each year, and this rate is estimated to be 1,000 times higher than the natural extinction rate (1). Human beings are causing irreversible damage to the oceans and their wildlife, which is being led by two major reasons: Commercial fishing or over-fishing, which damaged the marine environment and caused a loss in the marine life diversity, and pollution, which is a primary way of the extinction causes that drastically modifies the marine life habitat. As a result of the commercial fishing and pollution, many of the marine species will start disappearing of the oceans. Briggs emphasizes that over-fishing “has induced population collapses in many species. So instead of having less than a hundred species at risk, as was the case some 30-40 years ago, there are now a thousand or more (10).”
