There is a huge problem with finning for shark steaks or shark fin soup. Because of this, some shark species have dropped by 90 to 50 percent (Choi). In the 80s commercial fisheries made the population of sharks go down even further. Approximately 20 to 100 million sharks are killed each year due to fishing (lovgren). This has caused the total shark population to drop 30 to 50 percent
Research displays that the rate at which sharks are killed is close to 100 million every year! There are so many causes which assist with Sharks being on the verge of extinction, one of which includes human activities. First and Foremost , Shark finning refers to the removal and retention of shark fins and the discard at sea of the carcass. This means that for commercial purposes poachers cut off the shark 's fin, (while its still living) and tosses it back into the ocean. This is a detrimental problem because unable to swim, the sharks sink to the bottom of the ocean where the remains are eaten by other fish.
They tried to close SeaWorld. "Blackfish" a film by Gabriela Cowperthwaite is dated in 2013. This is about Whales that get frustrated and kill people. They are kept in pools that are clearly not the ocean. Sea World and other facilities like Sea World need to make a bigger pool or never own whales because they belong in the wild.
The movie “Jaws” is actually why a great number of people are afraid of sharks. This movie has also greatly impacted great white sharks and their numbers. The movie created this false notion that great white sharks were human-killers that wanted nothing more than to eat humans. Because of this false notion there was a lot of hatred formed and lots of fisherman were targeting the great whites. There was even “shark tournaments”.
Provided that sharks have not been fished out of certain areas it is reasonable to assume that their disappearance would be a result of the destruction of a suitable habitat. The fact that shark species are so diverse and inhabit every ocean on the planet makes them key players essential to the ocean environment. Yet despite their importance in the marine food-chain they remain a low conservation priority. For all their evolutionary success and apparent menace, sharks are incredibly fragile, unable to withstand the increased pressures forced on them by the voracious world fishing industries. This is partly due to the fact that sharks are slow growing animals that mature late, live long, and have a low reproduction
Annual tolls because of sharks are much less than deaths resulted in meetings with crocodiles, tigers or elephants. Last two representatives of the huge terrestrial fauna kill around 100 people each year, while sharks have around five victims on their account. Meanwhile, tigers and elephants already had law protection, when the documentary was created, while sharks were treated as a source of valuable product (their fins) and a monster that should be killed before it would get an opportunity to attack. Numbers, mentioned by the film, created the impression the situation is totally unfair. As if officials today will forget about their efforts against the ivory black-market
These sharks have slow growth rates and reach sexual maturity at a relatively late age compared to other marine fish, which leaves their population vulnerable to any outside sources (Musick and Musick, 2011). Sharks have been apex predators in the ocean for millions of years, however, the populations of sharks have been at risk for years as a result of many different factors. The impact of overfishing on shark populations has risen into the public eye over the recent years due to several documentaries and movies that have been released recently. Sharks are particularly vulnerable to over-exploitation due to their K-selected life strategy, having slow growth rates, long life spans and due to them reaching sexual maturity at relatively late age compared to that of other marine organisms (Stevens et al., 2000). Fisherman fish for sharks in order to get their fins, which is used to make shark fin soup (a delicacy in South-East Asia).
An excerpt from “Sharks Endangered” written by Sharks World Website states that “M[m]any types of sharks are at risk for becoming extinct.” If some shark species go extinct then there will never be a chance for those sharks to re-populate and the whole ocean would be changed forever. Sharon Guynup, a writer for Science World, claims that “W[w]ithout sharks the ocean 's delicate ecosystem would be disrupted.” If sharks were to go extinct the whole ocean ecosystem would be wrecked. It is no doubt that sharks are disappearing and something needs to be done about
An article on whaling by Photovoices states, “Many paledang (whaling boats) have been sunk by injured whales trying to escape the harpoon. In some cases, the whale has even crashed its head into the hull of the boat, smashing it to splinters and causing it to sink with the terrified whalers struggling for their lives on the open sea”. This quote shows the dangers of whaling because it is common for men to be injured at sea. Whales are enormous creatures whos instinct is to fight for their lives if they are in danger, leading them to cause destruction on ships and kill the men who hunt them. Once the whale is dead, the task of bringing the whale towards the ship is even harder.
Killer whales were initially captured in the 1960s, when a female orca was captured and put into a tank. Two days into the female orca's stay she repeatedly bashed her head against her tank wall and perished the following day. Unfortunately, people did not heed or take any precautions from this traumatic incident and since then killer whales all over the world have been captured for entertainment purposes and have been stored in facilities such as SeaWorld. From these types of facilities incidents continue to happen such as killer whales killing their trainers, killing themselves, dying due to medical conditions, and more. Continuous accidents such as these have caused suspicion among the public of whether killer whales live healthy and prosperous lives in captivity and brings up the concern of ethicality.
