Exposition: Whether sharks should be culled or not has become one of the most controversial issues in modern society. However it has become significantly more apparent that sharks should not be killed and this expository will be focusing on why sharks should not be culled. If the top predator of a food chain is removed, then that may cause the end of many more species. By removing the top predator of the food chain, this interrupts and disrupts the entire food chain and the animals on it. Firstly, sharks play a significantly important role in the ocean as most sharks serve as top predators and are at the top of the food pyramid and so they play a vital role in the ocean ecosystems. They hunt old, weak and or sick fishes in the sea thus, keeping
This is true because you may think that sharks are everywhere in the ocean. This is not true. They are sometimes found in an unusual place, but this is because with us taking over their habitats, and polluting them where else can they go? We have all of the lands, but we also take over the ocean, home to many sea creatures. That just makes us selfish. We can’t get mad at sharks when they would be perfectly fine if we just left them and their home alone.
Sharks can play an important role in an ecosystem and are referred to as a cornerstone species. They are apex predators and the larger sharks are not hunted by any other animal in the wild. Their role is to keep ecosystems’ fish populations at the correct levels.
In Australia, sharks kill an average of three people every year. In Queensland 2017, to counter this, 667 sharks were culled to protect human’s safety on Australian beaches along with 100 accidental deaths of turtles, dolphins and dugongs. This was done with no scientific evidence to support that culling would work. All over the world 90% of shark species are threatened to become extinct with people killing 273 million sharks every year. This is why we must ban and make sure shark culling stops and never ever starts again. Shark culling is ludicrous, you have more of a chance dying from a coconut falling on you than a shark attack, coconuts actually kill 150 people every year does this mean we are going to kill all the coconuts? Here are a few arguments why shark culling must stop.
One of the major problems is shark finning. Shark finning is the practice of removing the shark’s fins after it has been caught. They keep the fins and the body is usually thrown back into the sea, and usually the shark is still alive when this happens. When this is done sharks are not able to swim, and eventually the shark dies from suffocation, blood loss or being eaten another predator. The reason why the fins are kept are because shark fins are one of the most expensive food items in the world and can be worth more than over $400 per kilogram. One of the problems with finning and the selling shark fins is that it has caused a lot of declines in shark populations. Shark finning is unmonitored and unreported so the actual amount of finning is unknown. Finning is done at random and unbiased, they go after any species, sex or size of shark. Research has been done on some of the fins brought in by fisheries and it shows that even fins from great white sharks are appearing in shark fin
Every Jaws fan knows the shark gets it in the end. What they do not know is that too many sharks have gotten it; and that has caused a rapid decline in the shark population over the past thirty years. Since the 1970's, sharks of the Atlantic and Gulf of Mexico shores have declined eighty-five percent. Sharks are vital animal to our world's ecosystem, and if the decline is not controlled; we could be facing devastating problems in years to come. Information has been obtained from two books: The Shark Almanac by Thomas B. Allen and Sharks, An Introduction for the Amateur Naturalist by Sanford A. Moss. Sources also include a number of online references, among them BBC News, ENS News, The New York Times, and two online scientific
Arising over 350 million years ago, the shark species has been labeled as a human devourer. Now, with the increase in human population, the demand for shark meat, fins, and cartilage are at an all time high; therefore, the existence of the shark is becoming a concern (Budker 1971). Individuals are conditioned to think of sharks as a negative aspect to the environment, which is prolonging the effort to save shark species from becoming extinct. With that in mind, some private as well as national organizations have accepted the challenge of educating and informing people about the existence of the shark specie and its importance to the sea.
Shark culling has become the new issue for Australian media. Shark culling is not the answer for safer oceans. We would be far better allocating resources to achieving a greater understanding of ecology and behaviour of these large predators. Tagging sharks and following their movement over time will show were they are likely to attack next. The marine ecosystems needs the sharks at the top of the food web, removing the sharks you would see more lower ranked fish. The marine ecosystem will have to do some
One reason for culling sharks is that when there are sharks in populated areas, people’s lives are in danger therefore if
Fish 1and chips, messed up ecosystems and broken food chain. Why do we have to cull our beautiful sharks that have done no harm to us? I have conducted a research about shark culling and why people do this. I strongly disagree to shark culling. I mainly think that we should just keep an eye out on the sharks in the ocean. They only mistake us a seals and eat us. We should all incorporate and help increase the population of sharks again. Now why do people cull sharks and how can we prevent this? What does shark culling affect?
Blackfish, a documentary by Gabriela Cowperthwaite, analyzes the horrific treatment, containment, and use of Orca whales within entertainment facilities. The discussion of treatment began in 2010, when Dawn Brancheau was killed and drowned by the whale, Tilikum. Since this incident, there have been multiple investigations into SeaWorld and similar facilities. It is argued that the whales should be released from these facilities due to the posed dangers they have to humans, and themselves.
People visceral when they see a shark and they try to capture and kill it. Only some people want to protect sharks. Sharks help by keeping the fish population down First, we can protect sharks by doing little things such as stop finning sharks, picking up our trash. Next people destroy environments by oil spills. Not picking up trash. Last if people don’t stop finning sharks and not throwing their trash away our environment will smell bad and we will have no sharks left.
Thesis: Sharks are a vital part of our ecosystem, and killing them disrupts the delicate balance of the ocean.
More and more people have been introduced to a very dangerous practice called shark-finning. Even the people who are aware of the harmful effects they bring still continue on doing it. People are afraid of sharks due to their fierce appearance and the bad publicity they get such as the movies wherein sharks attack humans. Only about 5 people are killed by sharks every year. In fact, vending machines has a higher death rate of 13, while ants can kill about 30 people annually. Sharks are very beneficial to us, why do people keep on harming them? Why is shark-finning so important? Shark-finning gives both advantages and disadvantages economically, politically, cultural, societal, and environmental. It is important to recognize the
Sharks are one of the most feared carnivores in the sea. There are 365 species of of sharks in the sea as we know today. All sharks are carnivores. Most of them eat live fish, including other sharks. A shark's most common natural enemy is an another shark. Most sharks eat their prey whole, or they tear off large chunks of the bodies. Some sharks crush their prey. Others take out small pieces off flesh from large fish. Sharks also feed on dead or dying animals. Sharks have the reputation of attacking human beings. But less than 100 shark attacks a year are reported throughout the world. Sharks are most common in warm seas and oceans. Whale sharks, are the largest shark known to man. Sharks are classified in the order
II Over the years there has been a huge drop in the population of sharks, because of the popularity of Shark fin soup in china, and this can later on lead to the ocean ecosystem to be disrupted, if sharks are extinct.
