Recommended: Introduction to shark finning
Shark finning is the practice of slicing off the shark's fins while the shark is still alive and throwing the rest of its body back into the ocean. Sharks thrown in shallow water will fall to the ocean floor die from either bleeding to death or drowning. If the shark is thrown back in deep water they can actually implode due to rapid changes in pressure within the shark’s limp body. They can also die by starving to death, being eaten by other fish. Shark fins are used to make a soup that is considered an Asian "delicacy". The reasons that sharks should be admired and not hunted are almost endless. Despite creating easy income for third world nation’s, shark finnig is a barbaric practice that needs to end Sharks are some of the most ancient species that have ever existed on the Earth, dating back over 400 million years; well before the time of the dinosaurs. There are around 500 distinct varieties of sharks and due to shark finning, some shark populations have decreased by approximately 90% . The diversity in sharks ranges from the breathtaking to the mundane to the downright eerie. Previously thought to be strictly saltwater animals, some species are also known to live in freshwater . Sharks are extra sensory animals and can detect the slightest changes in their environment. They can hear sounds inaudible to humans for over a mile, and can sense the smallest pressure changes around their bodies; both are key in a sharks hunting ability 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...

...r $100 a bowl, and is a traditional wedding meal that shows the brides family how affluent the grooms family is. A common tradition attached to shark fin soup is that “longer noodles mean a longer life” . High demand for shark fins has driven the price to around $300 per pound!! Once exclusive to China, shark fin soup is now becoming a popular dish around the world. Aside from the moral implications, there is another reason to shy away from shark fin soup; “it may be detrimental to neurologic health” . Tested fins were found to contain the toxin BMAA, that when ingested increases the risk of Amyotrophic Lateral Sclerosis (Lou Gering’s disease), Alzheimer disease, and Parkinson disease . International law for the conservation and management of sharks is fragmented and piecemeal . However conservationists are making progress towards ending this destructive practice.
The Great Shark debate – to cull or not to cull, has been at the forefront of the minds of conservationists, as well as the general population for many decades now. The opinions of everyone are divided, according to their personal experiences, and views on what is right and wrong for the environment.
...doesn't have to exist. If there aren't many sharks left, just about everything would be affected. From the food web to the climate which would then link to climate change. People should focus on the BIG problems and worry less about the smaller problems that wouldn't affect everyone. If swimmers and surfers would take a chance and risk their lives in the sharks homes then it's their decision, we shouldn't have to worry about that. Each and everyone of us has a brain, which is used for thinking and creating new ideas. If everyone speak out then the world would hear our ideas to solve the problem. It doesn't matter how stupid your ideas may sound or if you're not a celebrity. Everyone has a voice! If everyone tries to stop the culling of sharks then the law will one day be abolished. We can set an example for other countries to follow! Let's show them what we can do!
But occasionally the younger sharks are preyed on by bigger sharks that do not necessarily have to be Bull sharks they can be become prey to any larger species of shark and occasionally a crocodile. However there are parasites like Pandarus sinuatus, and Periscopus dentatus that use the surface of the shark’s skin and use it to survive (Curtis). Though that does not in anyway decrease or increase the economic uses for the bull shark, its effects on the environment, or level of danger to humans. In certain places around the world the amount of bull sharks is decreasing slightly, because sharks can be harvested to make fish food, for their meat, for oils, and their fins for shark fin soup, or in asia their skin can be used to make “good leather” (“Bullshark”; Curtis). Even though their numbers are thought to be decreasing according to the International Shark Attack Files, otherwise known as the ISAF, has reported that there have been at least 70 reported unprovoked attacks on humans of which 17 were fatal, but that is only the known number of the reported attacks by bull sharks there most likely have been many more attacks that went unreported (“Bullshark”; Curtis). They are known for being one of “the most dangerous sharks in the world” because they along side the tiger shark,and great white they are the most common sharks to attack a human
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): Shark finning affects the shark most clearly on an individualistic scale. The removal of the shark’s fins makes it nearly impossible for the shark to swim once it is dumped back into the ocean. According to author William J Bennetta, many species of sharks, known as “obligate ram ventilators”, lack the ability to pump water through their gills if they are not constantly moving, and “presumably asphyxiate if unable to move” (Bennetta, 1996). Along with all the cuts, gashes, and beatings that come along with shark finning, most sharks that undergo finning die a very long and painful death due to loss of blood and suffocation.
How many more fatal shark attacks will it take for someone in authority to acknowledge the damages, economically and socially, caused to human beings by sharks? We must legalise the culling of sharks. Sharks do not only brutally attack us humans but they also kill us. Culling sharks may not be the most pleasing way to find a solution but it is the most effective, quickest and easiest method. Scientists have argued that culling sharks will bring the ecosystem crashing down but this in fact is not true.
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 ...
reenland sharks are among nature’s least elegant inventions. Lumpish, with stunted pectoral fins that they use for ponderously slow swimming in cold and dark Arctic waters, they have blunt snouts and gaping mouths that give them an unfortunate, dull-witted appearance. Many live with worm-like parasites that dangle repulsively from their corneas. They belong, appropriately enough, to the family Squalidae, and appear as willing to gorge on fresh halibut as on rotting polar-bear carcasses. Once widely hunted for their liver oil, today they are considered bycatch. For some fishermen, a biologist recently told me, netting a Greenland shark is about as welcome as stepping in dog poop.
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.
...te shark slaughter all around the globe. The easiest way to help stop this is to go to one of the many websites developed for this very reason, and support them. Sharks cannot speak for themselves, so we must speak for them and stop shark slaughter!
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.
Many species are endangered or at risk of becoming so due to this. Smaller sharks, such as the dogfish, have less issue of this due to the lack of fishing and industry they pose. Larger sharks are also often able to avoid population drops and fishing, simply due to the cost of catching one outweighing the benefits. The sharks that are hunted are common species such as great whites, tiger sharks, and other oceanic breeds that are easily found. When a shark is caught, it is either killed for its teeth and scales or for the purpose of finning. If the shark is finned, the pectoral, dorsal, and often caudal fins are removed and the shark, usually still alive, is thrown back into the water. Unable to swim and hunt, it soon dies.
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

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.
