Sharks and humans have interacted with each other for many centuries. Great stories have come from these interactions; in these stories, sharks are usually portrayed as the antagonist. However, in all of actuality, humans are the antagonists. We are lead to believe that sharks are highly dangerous, but humans pose more of a threat to sharks than sharks do to humans. In the asian culture, sharks are finned to make shark fin soup and then they are thrown back into the ocean, alive, finless, and helpless. Shark finning should be banned globally, it is a cruel practice that is causing a decline in the shark population as well as a negative impact to their ecosystem. Recently, there have been organizations and laws that are trying to prevent this
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.
Every year hundreds of sharks get killed just because people fear them. Western Australia has brought in the Shark Culls after a series of fatal attacks. Most of these people attacked are usually surfers, swimmers or shark haters. Now imagine this, what if you were a shark swimming and suddenly someone tries to hunt your down, how would you feel? We wouldn’t like it very much if the sharks did the same thing to us. In the following paragraphs, I would give you three reasons on why Shark Culling should be abolished not only in Western Australia but also all around the world.
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
Great White Sharks play an important role in the ocean, and it is their home territory. We, humans, intrude their home and we run our own risk of being attacked. Due to the sharks being a skill, natural predator of the ocean, its only normal for them to attack humans. Therefore it is not entirely the sharks fault, it is mainly the humans, which is why I choose to conserve the animal. (CONSERVE)
Watching a movie where hundreds of swimmers on a beach are in a complete panic because of shark attacks makes a person scared to swim in an ocean, lake, or even a pond. Not only movies, but also documentaries of shark attacks stress how dangerous sharks are. In reality, are sharks really that dangerous or is it how they are portrayed? Stephen R. Palumbi who is a Professor of Biology at Stanford University and also the Director at the Hopkins Marine Station at Stanford wrote an article about other animals living in the ocean that are more dangerous to humans than sharks. In fact, he has written books about creatures in the water such as The Death and Life of Monterey Bay, and The Evolution Explosion. In addition, his son Anthony R. Palumbi is a novelist and a science writer that has written for Atlantic and other publications (Princeton University Press 1). Together they co- authored an article titled “Forget Shark Week: They aren’t the only fish in the sea” that was published the Los Angeles Times.
Scientist are trying to find a way to keep the petrifying creators called sharks from harming their self’s and people. For instance, researcher found out magnets and electricity mess with these overgrown fish’s Ampullae of Lorenzini, which are special sense organs that assist with them finding their pray. Sharks are causing problems for humans and two ways to effectively solve this problem is with magnets and electricity.
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). Coral bleaching is not isolated to one select reef, but rather many reefs all around the world. Mass coral bleaching has become more widespread and frequent over the recent decades, often resulting in high mortality rates (Pandolfi, Connolly, Marshall
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 is a cruel and violent act, to say the least. Granted that there is economical profit to be had from shark finning, the massive loss incomparably outweighs the profit. Most, if not, all humans would not enjoy having their limbs cut off and being left to die. It is simply inhumane and brutal. However sharks are experiencing this very thing, and the fact that they cannot express or protect themselves, is leading to the death of hundreds of millions of innocent sharks annually. Odds are that as you are reading this, a shark was killed. While sharks may not be the most adorable animals on the planet, they certainly are living creatures, and they feel pain just like us.
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,
Sharks has been categorized by a cartilaginous skeleton, which means they are a group of fish that have skeletons made up of cartilage, their tissues are more flexible and lighter than bones (DefendersOfWildlife, 2016). Research shows that there were more than 465 types of sharks in the ocean for the past hundred years, but unfortunately, sharks are in the danger of extinction today. This is mainly because of the slow reproducing and growing rate of shark, which leads to the dying rates are higher than the reproducing rates. Shark is killing mercilessly by human, and shark finning is the main cause of the huge loss of sharks. To be more specifically, shark finning is a practice where the fisherman removes the shark’s fins and throws its still alive body back to the ocean.
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).
