(Heimbuch) They maintain species diversity by preying most species. They act as a crowd control to help maintain ecological balance. Sharks are also a source of food for other sharks and killer whales. (Heimbuch) Without sharks, the balance of the ocean collapses and has a devastating effect. (Heimbuch) Many shark species are endangered species and are in danger of extinction. Researchers estimate that by 2017 20 sharks will be extinct due to overfishing.
Humans do not limit their effect on the most common fish in the menu. From turtles to bats to marine mammals, exotic marine life is hunted. For example, the number of sharks is reduced by 80% worldwide, and one third of sharks are now in danger of extinction. The top marine predator is no longer a shark, but we are. The decrease in the number of sharks had a major impact on the ocean ecosystem. It leads to a further increase in the number of fish in the food chain, which in turn leads to the collapse of very small marine life like plankton. If there is no minimum creature, the whole system is threatened
Sharks are another example of murder known as a shark's fine and are in danger of extinction. According to the reporters of the Americas, "With the reduction of the number of sharks and the increasing threat to habitat, humans play an essential role in the survival of these ancient marine life." (Balaguer) Sharks It is a regulator of the food chain of the marine system. As explained in the article of National Wildlife (Dupree), they restricted the growth of seeds by cleaning it and eating it by eating corpses.
Sharks are a wonderful ocean carnivorous animal, the most powerful creature in the ocean. However, 25% of sharks are currently in danger of extinction, they are said to be on the brink of extinction, or nearly extinct crisis. Because sharks are usually slow to breed, the constant threat of attacks, including shark fin, bycatch, and marine ecosystem threats, has drastically reduced the number of individuals that have already been difficult to monitor. It is impossible to know how many sharks are killed each year for illegal and undocumented fisheries but it is estimated that 73 million sharks are killed each year for "fins" It will be. Usually it is still alive, throwing out the body from the ship, dying there, drowning and being eaten. The fact that millions of sharks are being killed is also a major problem of wildlife protection.
