Everyone knows the famous opening tune to the famous 1975 Spielberg movie Jaws, which portrays the chaos that sharks can cause. From then until now, movies that showcase the ever-violent personalities of sharks have been popular in the media. They are seen as the face of oceanic brutality, whether they bite off people’s arms or cause turbulence in beach parties. Little does the world know about the dangers that we, humans, do to these natural predators of the oceans.
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 ...

Shark nets have been implemented in locations across the world in response to shark sightings and attacks. Nets are submerged beneath the surface of the water, roughly 200 metres from the shoreline. The meshing is designed to be large to capture sharks, leaving them to struggle before eventually drowning under the weight of their own body. The meshing allows small fish to pass through, however captures larger fish and marine species. Shark nets provide no discrimination between common, vulnerable and endangered species, resulting in a high mortality rate for a variety of marine wildlife.
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
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.
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.
Specific Purpose: To persuade the audience to go online and sign a petition to help stop shark killings and to support the entire Racing Extinction cause in order to save species around the world from going extinct.
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.
In Chinese tradition, Shark fin soup is called as “a celebration soup”, which people eat it to celebrate in various occasions. Moreover, people also believed that shark fin consisted of diverse nutrition values which provide them virility, wealth, and power(Wolchover, 2011). These beliefs lead to the beginning of poaching for sharks, the top of food chain in the sea world. Surprisingly, although people are aware of the decreasing number of sharks since the old days, around hundred million of sharks are still hunted each year(Heltus, 2013), to be served on luxury tables surrounded by those believers in things that they do not even prove whether the belief is reliable. Therefore, in the generation that people are mostly educated, sharks should no longer have to be continuously killed for their fins.
Most people think that sharks are large, fast-swimmers, and savage predators. This is true of some species and groups should be interested of the appealing aspects of biology found within it: all sharks have an excellent sense of smell; some can detect electrical discharges; some sharks give birth to one of the

However, one just can’t judge a shark by looking at it. Although others see sharks as sadistic, barbaric creatures who wish nothing less than to eliminate them from the face of the earth, it is unmistakable that their population is dwindling to an extent where they need refuge from
This attack rate is surprisingly low considering that thousand of people swim, surf and dive in Hawaiian waters every day. Despite these statistics, sharks attacks remain a highly emotive topic in Hawaii. This reaction is unsurprising in a state that is economically dependent on tourism and recreational ocean use. Killing tiger sharks contradicts traditional beliefs of native Hawaiians, who consider these animals to be sacred ‘Auma kua’ or ancestor spirits.
Often when people go swimming at the beach, they are afraid of the possible risk of shark attacks. However, are these fears reasonable, or do people mistakenly believe that shark attacks worldwide are much more prevalent than they truly are? In this project, we will conduct an observational study to examine data on non-fatal unprovoked shark attacks that occurred globally in 2015. The data we will be examining comes from the Shark Attack Database which uses the Global Shark Attack File (GSAF), a spreadsheet of human/shark interactions compiled by the Shark Research Institute. This data is important because it will evaluate whether shark attacks worldwide are a common occurrence or are relatively rare.
Savagely cutting off a human’s arm is totally immoral, and yet fishermen continue to cut off sharks’ fins and leave them for dead. Shark finning is practiced by numerous countries, but only banned by a few. While it is well known that this barbarian and horrifying practice is severely endangering most shark populations there are only a few laws in a few places that regulate the shark fin trade. The reason shark finning continues to go on is due to the high market demand, weak legal constraints, and the ignorance to the fact that there are severe problems associated with it, both to human health and to the marine ecosystem.
I’m sure everyone here has seen jaws and heard that scary theme music that goes with it. Films like this have given a big reputation to sharks being dangerous and the threatening sea animals. The media also doesn’t help this! Today I will be arguing for the rights of these misjudged sharks and how this new “catch and kill policy” is totally wrong. I am sure that after this you will believe, like me and so many others that sharks are Jaw-some and should not be culled.
Introduction One particularly interesting sea creature is the whale shark, formally known as Rhincondon typus; it was first discovered in 1828 by Andrew Smith (Rowat 2012). This large fish is found globally in warm tropical oceans and prefers to stay within 200 meters of the ocean’s surface in waters ranging from 4.2 to 28.7 degrees Celsius (Stevens 2006). This creature can be found all across the globe in warm tropical seas. Aggregations of whale sharks have been seen off the coast of Australia at times, although it is primarily a creature of solitude. Whale sharks are filter feeders that consume plankton as well as small fish and are harmless to humans.
