Why is killing sharks bad?
Sharks play a vital role in the oceans in a way that the average fish does not. Most sharks serve as top predators at the marine food pyramid, and so play a critical role in ocean ecosystems. Directly or indirectly they regulate the natural balance of these ecosystems, at all levels, and so are an integral part of them. As they usually hunt old, weak or sick prey, they help to keep the prey population in good condition, healthy and strong, enabling these more naturally fit animals to reproduce and pass on their genes. The effects of removing sharks from ocean ecosystems, although complex and rather unpredictable, are very likely to be ecologically and economically damaging. Here are some reason why killing sharks is very bad:
1)Sharks are being fished at a rate faster than they can recover.
Due to overexploitation and lack of proper management, many shark species are under considerable risk of unrecoverable decline with some species having declined to near extinction in recent years. According to reports, sharks are being killed at an alarming rate of up to 273 million worldwide per year. Some experts predict that if

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
I have swum with Caribbean reef sharks in the Bahamas and have seen how beautiful and strong they truly are first hand. Sharks are a vital part to every ecosystem they are in and currently being killed at a rate that they cannot reproduce at. Alpha predators are a necessary component of eco-systems because they keep the populations of every trophic level below them in check. You can compare an eco-system to a skyscraper; you need every single part so the entire building does not fall apart. Sharks have the task of killing the wounded, old, and sick fish in schools to keep the stocks of fish healthy and plentiful.
To conclude, the ocean is ultimately the sharks home and it has been for millions of years and we are intruding on it though all of the point brought forward you can clearly see that rouge sharks should be let go sharks kill barley any people compared to a lot of others, they don’t go out of their way to eat humans and the general public is convinced by the media that sharks are evil man eaters this leads me to believe that sharks should be let be evacuate the beach and let the shark move on, once the shark has moved on think of shark prevention tactics such as nets, shark shields, extra patrols
This topic has made me think differently because usually sharks are looked upon as the predator by humans; however, in this scenario they are the prey. The decreasing numbers of the sharks has also impacted the food chains. There is now more prey with fewer predators and there is a risk that a new predator may evolve targeting other species.
According to research, sharks’ skin can change color when exposed to sunlight, similar to the way humans tan, and they can develop skin cancer as well. Looking at short term and long term effects, at first sharks would begin to reduce the amount of color change seen to their skin, and eventually, skin cancer rates of this species would decrease. Changing from animals to plants, a maple tree would experience effects as well. Sunlight is important to this type of tree due to the pigment and their need to change from green to red leaves. If sunlight were to disappear, at first it would be noticeable how the leaves were not changing from green to red, at least not as much.
The Great White Shark The Great White Sharks, known mostly because of their white underbellies, are one of the most powerful aquatic animals in the world. They can swim at about 25 Miles Per Hour (40 Kilometers per hour) because of their strong muscles and forceful tails. In addition to that, male Great Whites can grow around 11.5 to 13.1 feet long, while females can grow from 14.8 to 16.4 feet long. This paper will demonstrate how Great White Sharks are an important part of their ecosystem, how their diets work and will adequately describe their habitats. As predators in their ecosystem, Great White sharks help maintain the coral reefs and seagrass habitats.
Animals like killer whales depend on seals for food. If the seals disappear, the killer whales will also start to die of because of starvation. Some fish species will become overpopulated. This is because there won’t be any seals to eat them, and then that
People don 't understand that this doesn 't just affect whales, it also effect people to because the belugas play a very important role in our ecosystem. If we don 't stop killing or hurting them right now later down the road we will pay for it. Later on in life if you start to see overwhelming amount of bad fish for an ecosystem and they are destroying it because there are no predators to keep the fish population down. Beluga whale help keep the ocean 's ecosystem healthy by eating fish and reducing the amount of fish that are bad for an environment. Belugas also are good for the deep sea because when anything dies and falls to the abyss from the topside they go through different layers of the ocean.
marine animal I’m researching is The Great White Shark. They are also known as, White Death and White Pointer. Great White Sharks are located off the coast of California, Australia, South Africa and the northern United States. Other continents and countries call them Tommy Sharks, Blue Pointer, Uptail, Maneater, etc. Great White Sharks are mostly infested in the USA and Australia and have caused 188 deaths in total.
So if we have shark nets set up, people will not swim out as far into were sharks swim. Keeping both humans and sharks separated and safe from each other. The top CSIRO great white shark expert Dr Barry Bruce thinks that shark nets reduce the deaths of people "Shark nets certainly reduce risk because they catch and kill sharks that have the potential to bite people," he said. A Queensland study showed that at beaches which had shark nets, there had been only one fatal attack since 1962 compared with 20 fatal attacks between 1919 and 1961 at the same beaches. So they do work.
Without fins, the shark is unable to move around and die of bleeding profusely. Finning the great white sharks is having a big effect on their population. With their slow growth and reproductive rate, the great white is facing possible extinction. It is a difficult process to bring back their population back because
Sarah Freeman’s article in The Ethicalist explains the negative effects humans have on the ocean. These negative effects include plastic pollution, global warming, and worst of all, overfishing. Overfishing occurs when a fish species is wild caught faster than it can reproduce. This leads to fewer fish in the ocean, meaning less marine biodiversity (Freeman). After Freeman spends most of her article explaining how the oceans are suffering, she then starts talking about what can be done to prevent a baren sea.
Sharks have been swimming the world’s oceans for more than 400 million years - 100 years before the first dinosaurs appeared (Griffin et al., 2008). Sharks fall under the kingdom Animalia, the phylum Chordate and the class chondrichthyes. There are more than 400 known shark species found in the ocean (Musick and Musick, 2011). In the ocean, sharks help maintain the health of ocean ecosystems and help regulate and maintain the balance of the marine environment (Griffin et al., 2008). 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).
If sharks go extinct it can cause a disastrous effect on the food chain; coral reefs could possibly die and fisheries could collapse. Keeping sharks alive helps keep a healthy and regular balance in marine life. The oceans
1. 90-100 million tons are killed and wiped off the planet each year. Consisting of some of the most beautiful creatures on the planet. Fish are a primary food source to 3.5 billion people worldwide and the depletion of the species is leaving millions of people hungry. Over fishing is a huge problem that needs to be stopped.
Hence, overfishing threatens coastal nations down to the local level, devastating communities whose dominant sources of labor and revenue hinges on healthy, plentiful stocks of fish. Also, marine life imbalance may affect the targeted fishing of top predators such as billfish, sharks and tuna that eventually disturbs marine communities. In fact, it is causing increased abundance of smaller marine animals at the bottom of the food chain. This in turn has impacts on the rest of the marine ecosystem, such as the increased growth of algae and threats to coral reef health.
