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.
National Geographic states that “Over 375 shark species have been identified, but only about a dozen are considered particularly dangerous. Three species are responsible for most human attacks: great white (Carcharodon carcharias), tiger (Galeocerdo Cuvier), and bull (Carcharhinus leucas) sharks”. Almost every recorded attack happened because of the shark’s curiosity, misidentification and plain human stupidity. During a shark breeding season, the
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
The delicacy is aptly named for the ingredients that go into the pot during preparation. Sharks are often fished for just their fins, which are brutally sliced off, and thrown back overboard. Without fins, they can no longer swim and are left to bleed to death after sinking like a stone or eaten alive by fish. This process is brutal and excruciating for the creature, and no living organism should be subject to such a slow and painful death, especially not sharks that have already been classified as an endangered species. Unfortunately, sharks have been commonly perceived as dangerous to humans, and thus we have been
The shark is classified as a top predator and the fish a smaller carnivore. Since the smaller carnivore is the main source of nourishment for sharks, the sharks eat the fish. This makes the relationship a predator-prey relationship. The last three relationships are different examples of symbiosis, which is the interaction between two living organisms. The first type of symbiosis is a form called mutualism.
Once the whale has decayed the bag is free to kill other marine life many more years to follow. One plastic bag can potentially kill at least a single an animal every three months because of inhalation or digestion. Once the amount of plastic bags littered is considered, 1.5 million to 3 million, the extremely high amount of lives lost is realized. The death is not quick for any of them either, they will suffer a slow and excruciating death. This is because their digestive system becomes interrupted and the plastic causes intestinal blockage and toxicity.
First we will be talking about the negative effect. According to USGS (The United States Geological Survey) ever since the Introduction of Zebra Mussels to the Great lakes,” Large populations of zebra mussels in the Great Lakes reduced the biomass of phytoplankton significantly following invasion. And the Diatom Abundance as decreased by 82-91 percent.” Zebra Mussels consume plankton as food which leaves Small fishes such as young sportfish without as much food. These small fishes depend on Plankton for growth and survival. The Zebra
We don’t live in the sea yet we are still affected by marine pollution, why? Because 70% of oxygen we breath is produced by marine plants thus if marine plant are affected by the pollution and there is shortage in oxygen or animals eat those affected plants in the end we will be affected. Japan being one of the biggest consumer of seafood can be affected, their people can be affected as humans seeing as we are on the far end of the food chain thus if a fish living in the contaminated waters of Japan falls ill, is then caught and served as food to the people ultimately they will fall sick too. When this takes places the consumer can face a great deal of problems from hormonal problem, kidney damage, reproductive problems and nervous system
Also, storms can destroy reefs, also often caused by humans affecting the environment. Around 50% of our coral has died, and this has a major impact on many other organisms, and the world in general. Many fish live in reefs, and need it survive, and this ruins the ocean, the most important part of the Earth. This comes back to hurt us as well. Eutrophication is a process in which excess nutrients
