Food Chain: The Effects Of Shark Extinction On The World

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 are important to our ecosystem and humans needs to protect sharks. The number of sharks have declined by 80% and the main reason is humans. Secondly sharks are important to our ecosystem to keep things balanced. Another reason sharks should be protected is because sharks can be used at a drug to treat human viruses. In conclusion this is why humans should stop the killing and start

Firstly, if sharks numbers drastically decline then it will throw the food chain out of whack. Sharks eat the big fish, who in turn eat the smaller fish, which eat the smaller fish which eat the algae. If sharks were to become extinct then certain marine groups would overpopulate which would endanger a large number of other marine species making them either very rare or even extinct. “According to one study, without sharks the number of mid-level predators will increase many fold. These mid-level carnivores will eat most of the algae eaters. As a result, the seas will be choked with algae and its excretions. The water will become slimy. Sunlight penetration will be reduced. It will decrease coral reefs very soon. So, many thousands of dependent species will also go extinct.” (All Five Oceans, 2016) For example, do you like to eat shrimps, oysters or crabs? Because if shark culling continues then these species will become almost extinct. This is because sharks feed on rays who are the main feeders of these foods, if sharks become extinct then rays will overpopulate and with so many rays feeding on these foods then they will become rare and maybe even extinct.

Sharks are vicious creatures and eat humans. Don’t go into the water if you see a shark nearby or they will come after you. These are a few of the many things you will hear from the television or even people you may know. Humans are not a part of the shark diet so it is highly unlikely that a shark would randomly go after a human. The media likes to make their shark stories more exciting by adding words like “aggressive” or “threatened.” There was a total of 4 deaths caused by sharks in 2014 which is a large contrast to the 11,417 sharks that are killed per hour by humans. sharks) need to be preserved and protected in order to preserve our oceans. Laws that are more strict should be implemented in order to achieve this goal.

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.

The things that sharks are being killed for is sickening. So far, humans have decimated about 90 percent of the world’s shark populations for the sake of shark tooth jewelry and jaws that tourists buy in massive quantities, sharkskin accessories, phony medicines made from their cartilage, and a huge range of cosmetics, deodorants, moisturizers, sun tan lotions, and lip balms that use shark liver oil as a base because it makes our skin soft. (Check the ingredients of these items before you buy. If they contain “squalene” or “squalane,” leave them on the shelf.) (M. R., Ph. (2015, February 08). The Most Misunderstood Shark Fact Of All Time. From

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

The Shark’s place in the marine ecosystem is as a predator at the top of the food chain as there is no natural predator of sharks. Sharks are not very fastidious about what they eat but their diet generally consists of seal, crab, squid, lobster and fish. If sharks were to become extinct there would be an ecological cost. The marine life that is the shark’s food source would start to overpopulate with nothing to prey on it. One possible reason that sharks are coming closer to shores is that their natural food source is diminishing due to overfishing by humans. To stop sharks from being too near to popular swimming locations, fishermen need to expand or change their hunting areas.

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?

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.

Some people experience the scarier side of sharks, but throughout history it is a proven fact that beside four species of sharks; tiger, bull, oceanic white tip, and great white sharks, they are not killing machines. Their species however has been preyed upon for many years. The fear that is instilled within people shows up as the killing of millions of sharks to overcompensate. Thinking that if sharks were no longer around would somehow ease their fears.

The environmental factors are about the conditions and the surroundings that we live in. Shark finning is an awful practice that causes negative impacts for the environment. Once the sharks are caught, the fins are cut off and are returned to the waters. Almost always, they don’t survive due to predation to other animals, blood loss or from suffocation. The Shark Population is massively decreasing. Specialists estimate that approximately 100 million sharks are killed. In the marine ecosystem, sharks are probably the primary predators and ocean takers. They are apex predators who are responsible for keeping the population in balance. They have been around Earth for 400 million years. The Earth is 70% covered with water and it houses 80% of life on Earth, which is why it’s important to sustain this

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.
