Sharks have a maor role in their ecosystem. Sharks eat smaller sharks as well as marlin to keep the population down. Sharks not only keep the prey populatin down but as well as the predator population would increase. They need to keep themselves healthy so that they could produce offspring. Sharks keep sea grass beds and other habitats healthy. When sharks eat their prey which sometimes might be herbivores their would not be many of them eating the grass of seabeds of the ocean. This is one good reason for their being sharks. If the population of sharks were to go down their would be a huge change in the ecosystem. The crab and lobster population would go up. If this were to happen most businesses that sale seafood would have a good chance …show more content…
Scientists have researched that sharks could help cure some diseases. Sharks tissue appear to have anticoagulant and antibacterial properties. Viruses like the flu or the common cold could helb be cured quicker because of the shark’s tissue. This also explains why sharks aren’t likely to give humans diseases. It’s because they cannot get sick themselves thanks to their skin. Sharks could help us as well. Sharks help the carbon cycle. When fish die of these matter goes to the seafloor, deep sea sharks would eat them. When they eat the dead matter of the fish the carbon releases from their bodies. All life on Earth needs carbon knowing that the ozone layer is weakening and because of past air prolbems on Earth. The sharks play a big role just as the plants do for us. Their’s nothing more needed for everything than air. This is another reason why sharks help a lot. There are more reasons for sharks to be around. After reading this you should have known of the things that sharks help out with. Maybe Jaws is that bad of fish after eralizng how they help us. This essay wans’t made to prove that sharks are more dominant. Only to show how they are needed for us and the other species of Earth. Are you aware of the shark’s importnatce. If you do then explain
As they are at the top of the food chain, sharks play a very important role in the oceans in a way that an average fish does not. Sharks keep populations of other fish healthy and in proper proportion for their ecosystem. By preying on the old, sick or slower fish in a population, they prevent the spread of disease and prevent outbreaks that could be devastating. According to Ransom Myers from Shark savers, “sharks may be gone within the next decades if we continue to kill them, resulting in the loss of important foods that we depend on for survival, causing a marine ecosystem imbalance.” At the same time, I accept that shark nets could be useful, especially in shark infested areas that have been renowned as spots where many attacks have occurred, but I still believe, as you would, that scientists should spend more resources on working out why it is becoming more common for sharks to be entering shallower waters, looking for food – namely seals, who just happen to look like
So why do we need sharks? Well, Sharks help keep the ocean healthy and clean for over 450 million years. They also help remove half of the worlds green house gases and produces oxygen more than all of the rainforest's combined! Sharks are just as important as all the trees in the world because they have one thing in common, provide us with oxygen. Without the sharks help we wouldn't be able to get rid as much of the greenhouse gases as we want to, which means global warming would have a lower rate of happening faster. Most importantly they provide us with food. How? They would usually eat the old, sick or slower fish in the population of the ocean to the right size so the prey species don't cause harm to ecosystem by becoming to populated. They are also at the top of the food web. If all the sharks went extinct the entire food web would collapse causing many other species of fish to disappear. So instead of killing the sharks, we could lure them away to somewhere else. As they have a huge impact to the environment.
As I mentioned earlier, Sharks maintain the balance of the entire marine ecosystem! If the ocean’s ecosystem were to collapse, it would greatly affect life even on the surface. Sharks tend to eat fish who are much slower and sickly therefore they keep the population of fish in a healthier state. We depend on the oceans for the oxygen that we breathe because of certain species in the ocean that produce oxygen such as Phytoplankton, if Sharks were to be extinct, we would lose a great amount of the oxygen on Earth because the balance of living Phytoplankton and other species would not be enough. Furthermore, Sharks have been maintaining the balance of our ecosystem for 400 million years, if these sharks were to be gone, who would balance this heavy task? A number of scientific studies demonstrate that depletion of Sharks results in the loss of important fish and shellfish species from the food chain, including key fisheries such as tuna, which help the health o...
The bull shark may be responsible for many shark attacks in the world but I believe that we have no right to kill them. Sharks are very important to animals food cycles and if the food cycles get messed up it can greatly effect the world. In fact, the bull shark is more vulnerable to human impact due to their ability to live in fresh and salt water but many sharks that are killed are for either shark fin soup or their liver oil. The sharks liver oil has many uses now but it started as a machine lubricant. Another way that sharks die is by recreational fishing. The sharks can get caught up in the fishermen's nets and eventually suffocate and die. As an environmental community, I feel like we need to inform people about shark habits and how to keep sharks safe. The water is their home and we are
Sharks have also been subjected to medical research, games and competitions, jewellery, souvenirs and cosmetics. We need to take into consideration that sharks play a vital role in the natural world that we live in. it is imperative that we look after these majestic creatures and ensure they remain protected. We need to be aware of the dangers of sharks, swim in protected areas where there are shark nets, and do not swim after dark in the sea (especially not alone) as the sea is the sharks home. Humans should also be wearing wet suits as protection in the ocean. The sea is where they live, they swim freely and they eat – they do not particularly target humans but rather prey on food that is available to them in their habitat.
Shark slaughter has led to shark populations being rapidly decimated all around the globe. Fishermen report that sharks are also getting smaller because they are not being given enough time to fully mature. Although there are other fish that are targeted more than sharks, they are not exactly affected by the kind of endangerment that sharks are currently experiencin...
In 2015 only 59 shark attacks have occurred around the world compared to the millions of sharks killed by humans every year. Due to these accidental shark attacks people tend to think that sharks, especially Great Whites are evil creatures with malice intentions when attacks do occur; but, on the contrary that is wrong. Sharks are not the only beautiful and unique creatures in the ocean, they also play a vital role in our ecosystem; however, due to human interference they might not be around much longer, through awareness sharks can be protected from endangerment.
Sharks have been on this earth for nearly 450 billion years. To put that into perspective, the first modern humans date back to about 60,000 years ago ("Our Mission: To save Sharks and Mantas”). Since then, both humans and sharks have evolved into the predatory mammals they are today. However, with the quick development of humans, civilization and technology, humans have not been able to fully understand the ways of sharks, although the motives of other human celebrities have been easy to understand and decipher. Because shark attacks have been becoming more televised, and sharks have been known to be more of a “threat” to humans, shark research foundations, such as the Shark Research Institute and the Pelagic Shark Research Foundation, have been created to help give an understanding to these creatures. Over 100 million sharks are being killed each year, and there is a counter on the Bite-Back Shark and Marine Conservation website. As one spends more time on the home page, the number on the counter is constantly increasing, showing how many sharks are slaughtered in the year to come (“Bite-Back – Shark and Marine Conservation”). Even with research to show that sharks are valuable to the ocean and vulnerable, there are people that think otherwise (“The Pelagic Shark ...
Thesis: Sharks should be conserved because they are an important part of the ocean, attacks are often incidental, and human behavior influences the behavior of sharks.
... numerous herbal ingredients which are beneficial to human health; still, it is not directly because of on shark fins.
Sharks have been scientifically proven to be able to be trained and tamed by humans. For instance, Sharon Guynup says, "Scientists have taught lemon sharks to swim through mazes, ring bells, and press targets,” (“What Do You Know About Sharks?” 879). This proves that
Most people think that sharks are large, fast-swimmers, and savage predators. This is true of some species and groups should be interested of the appealing aspects of biology found within it: all sharks have an excellent sense of smell; some can detect electrical discharges; some sharks give birth to one of the
Many things about sharks are interesting and they have some general facts that are pretty fascinating. The first fact is how they find prey. Sharks have a lateral line or sensory system from head to tail. The canals are filled with liquid. When there is sound it causes the liquid to vibrate. Another fact about sharks is there natural enemies are humans. Humans kill sharks more than they attack us. Humans use sharks for food, they use shark skin for leather and shark teeth for jewelry. Sharks attack humans because they mistake us for prey. They take one bite and realize that we are not their prey. One scary fact about sharks is there bite. One shark bite is like being crushed underneath ten cars, stated the article,
Fin Whales play a huge part in regulating the food flow in the ocean by stabilizing the food chain. Without whales we would see species overpopulating the ocean, and the food chain will be interrupted. Whalefacts.org reports that even whale waste helps the environment by reducing the carbon in the atmosphere. They also showcase studies that have proven that other whales like the sperm whale's poop, "helps stimulate the growth of phytoplankton which pull carbon from the atmosphere to provide a cleaner and healthier breathing environment for all animals." Fin Whale and other whales poop also helps with the growth of phytoplankton, in which other species depend on for survival. Whales are detrimental to the ocean, they all play a huge role in
Sharks live in almost every part of the oceans, from coastal environments to deep-sea habitats. They also live in the warm waters of the tropics to the cold frigid waters of
