2016). Overall, in the past 75 years the global whale shark’s population has declined by 50% (Pierce, S.J. & Norman B. 2016). Whale sharks are protected species in 13 of 100 countries that they visit every year and is classified as a vulnerable species (Rogers M.
Body (30) A. Shark attacks are actually pretty rare for the number of people that enter the water every year. The risk of being attacked by a shark is about 1 in 11.5 million. Although shark population has declined every year, the number of attacks has steadily increased due to the human population growing. 1.
However, I caught a 42 inch shark in Florida (saltwater) which took me 20 minutes to reel in, and that is considered a small fish. They both have unique characteristics that make them completely different things. I’m going to prove that all fishing is not the same, saltwater and freshwater fishing are different sports based on dangerousness, cost, species, bait, and boat type. Most people assume fishing is a safe and easy hobby, however, fishing can actually be a dangerous activity. Saltwater fish have the potential to pull you into the water, bite you, or even sting you.
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
That adds up to about 11,417 sharks per hour and 100,012,920 every year. Co-author of “Sharks of the World” Leonard Compagno said, “The dawn of the latest extinction crisis was less than 20 years ago” (Compagno page 43). This over-fishing is destroying the ocean ecosystem by taking a vital part
Over 100 million sharks are murdered by humans every year, and it’s a high number for any animal but it’s endangering to sharks because they don’t breed very quickly due to their biological composition (NewsCurrents Read to Know). Sharks reproduce very slowly and they can’t keep up with the rate that humans are killing them off at. With that inbalance, they’re getting closer and closer to extinction everyday, but with a ban on finning that would cut down over half of those casualties and keep the sharks from dying off. Consequently, because they’re being killed off in large unmoderated amounts there a species of sharks already extinct and in "Bad to the Bone", written by Michael A. Rivlin, he writes “Because of such biological profiles, most shark fisheries have experienced brief booms, followed by long busts. To take one notorious example, in 1961 Norwegian longliners began catching porbeagle sharks in the Northwest Atlantic.
Their existence dates back to even before the conditions on earth were almost uninhabitable whereby there was lack of oxygen in the last millions years. This amazing feat is however overlooked by people and people tend to not value their existence. People are increasingly influenced to be more terrified and afraid of sharks and the media largely contributes to this propaganda. People are easily influenced by sharks since sharks are one of the most terrifying creatures to date. The film, “Jaws”, especially, has altered people’s view on sharks and sees them as the real monsters that still exist in the world.
2. THERE ARE NO CONSISTENT TRENDS IN EVOLUTION: In the evolution of sharks, we clearly see that there are no consistent trends in their evolution from the beginning of their existence, they are a species that are always changing or evolving as mentioned in the previous example. This is why we see the diverse amount of species of the shark family all over through the ages both prehistoric and present. And can clearly see the branching out of the species from is simplest form to various other forms, the branching of the shark family can be seen
In the Washington Posts article “Just how badly are we overfishing the oceans?” the author suggests that the populations of fish are declining due to overfishing. While it might be true that people are overfishing, they aren't fishing to the point of extinction. There is also a need for stronger regulations to help regulate the amount of fish being fished. The fish populations aren't being drastically affected by fishing but some regulations can help control the population. Fishing has been a primary food source for humans since the dawn of time and through multiple generations.
