Hook:
Picture this
You are a 200-year-old endangered Hawksbill Sea Turtle twisting yourself into a foreign knot. Thrashing for freedom, panic sets in as your realise you are helpless in your bending cage. The ocean turns from turquoise green to Prussian blue as the sun slowly pierces the shadows of your watery grave. Bubbles rush from your mouth like stolen phantoms as you begin to contemplate your own mortality. Slowly suffocating, hope begins to fade. Deeper and deeper you sink into unconsciousness. Euphoria sets in as your panic begins to ease, in your mind you remember freedom, just a memory but not so long ago, is this death? Is this a good death? You take one last breath, and let go of

the fear, the pain, the suffering. Introduction: Good morning/afternoon Mrs. Arnold and fellow students. I am here today to convince you to agree with me that shark nets should be removed from Australian waters. Sharks nets have been in place for many years, since more and more humans have been attacked by sharks in the waters around Australia and the world. While they have had some success, they are far from efficient at keeping humans safe, and rather act as a death trap for the innocent marine life, sifting around the ocean, going about their daily business. As with any natural habitat, humans should enter at their own risk. People don’t swim in crocodile infested waters do they? It’s not a new finding that sharks swim in oceans and spend their days seeking food? Is it? Perhaps humans should start taking responsibility for the food imbalance that has driven sharks to come ashore to find more food? I further contend that shark nets aren’t actually necessary or effective and there are other alternatives that should be considered. 1st Argument: Firstly, Shark nets cause an accidental destruction and killing of innocent marine life. There has been no statistics to show they cause any benefit to humans. Yet they have killed over 15,000 marine animals in Australia, and are still implemented as ‘life saving solutions.’ Endangered species, dolphins and even humans have all been victims of the vicious schemes brought to our beaches, so we as humans feel a false sense of security, in an environment that is not actually ours. This environment is one we can live without. According to CSIRO shark expert Barry Bruce “a shark net is not a barrier, but rather a fishing device.” A fishing device for 100 species of endangered animals, now tangled and fixed in the life taking devices, breathless at the bottom of the cold, isolated ocean. Furthermore, while shark nets not only kill innocent marine species, the nets are not a barricade and they do not prevent sharks from getting near our beaches and attacking humans. Shark nets are only 150m wide, 6m tall and usually set in about 10m of water. Therefore, due to their enormous size, sharks have the luxury to simply swim over and around them to access our shores. While, smaller, harmless and defenseless creatures are left to get tangled and to die by suffocation and starvation. While I understand that there is no easy solution to the problem of preventing sharks from coming in close to the shore and attacking surfers and swimmers, and shark nets attempt to solve this on going issue, I ask you, how many needless deaths of these majestic marine creatures will it take until “professionals” see they are pointless and attempt to implement actual life saving solutions into our oceans? 2nd Argument: Furthermore, humans should enter the ocean at their own risk, it’s the shark’s natural habitat. Shark nets are not the answer. We as humans would not be so stupid to jump into a crocodile infested environment, yet we swim and surf in shark swarming oceans. Would we consider to remove these crocodiles from their natural environment? Would we even begin to consider removing a 4 and a half metre albino headed crocodile after it attacked and killed a fisherman? We just believe that it was the fisherman’s fault. He entered the Adelaide river at his own risk and horrifically suffered the costs. So why don’t we feel the same about sharks? …………………………….EXPERT EVIDENCE OR CASE STUDY NEEDS MORE GUTS CA: While I accept that no human should die or be maimed while swimming or surfing, life’s unpredictable. We live it at our own risk. We get in a car and risk being in an accident, we catch planes and trains that could easily crash. It’s the individual’s own risk. 3rd Argument: Instead of using shark nets to protect humans from being shark food, perhaps marine people should take responsibility and correct the ecological imbalance that has resulted in a shortage of food for sharks.
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
humans. 4th Argument: Finally, shark nets don’t actually work, and there are more effective alternatives available. We have many options from marine biologists and scientists, that could prove to be more effective in combating sharks attacks, for example: sonic radiations, wetsuits, surfboards and sprays. So why are we still choosing to use these ineffective nets? Did I also mention that shark nets costs 1.4 million dollars for an 8-month contract that operates on 14 days of the month on beaches between Wollongong and Newcastle only? That’s your parents, Mrs. Arnold and every tax payer in Australia forking out of each pay to sustain something that is, well, hardly sustainable. However, there have been some instances where shark nets have been effective in deterring sharks from entering highly populated beaches and surfing territory. This still doesn’t justify their use, especially at the cost of the lives of other sea creatures. Conclusion: In closing, I urge you to consider my arguments before you come to your own conclusions about the worthiness of shark nets. Keep in mind apart from being virtually ineffective, they are responsible for more than …% of marine animal deaths. Furthermore, there are more effective alternatives that could be used for those worried about being mistaken as a seal. I argue, enter at your own risk, just like any other potential harmful situation. It’s your choice. So next time you read or hear a report about a surfer or swimmer, being attacked or having a close encounter with a shark, think about those nets. Would it have deterred the shark, or possibly have caught it? Or would that old Hawksbill Sea Turtle be tangled in its web of messy netting, dying, slowly?
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.
I am sure almost all of you have either been to or heard of SeaWorld. Today I am going to tell you about what they do to their orcas that they are trying to hide. I chose this topic after watching a documentary called “Blackfish” that goes into the behind the scenes of how SeaWorld treats its animals. I have since done further research online to prepare for this presentation. This is an important topic because you should know what kind of company you are funding and behaviors you are endorsing when you go on your vacations to this destination. Today I am going to persuade you that SeaWorld is corrupt and maltreats its animals, specifically the orcas. First, I will talk about the specific way the orcas are treated and how it affects them
Shark nets have been implemented in locations across the world in response to shark sightings and attacks. Nets are submerged beneath the surface of the water, roughly 200 metres from the shoreline. The meshing is designed to be large to capture sharks, leaving them to struggle before eventually drowning under the weight of their own body. The meshing allows small fish to pass through, however captures larger fish and marine species. Shark nets provide no discrimination between common, vulnerable and endangered species, resulting in a high mortality rate for a variety of marine wildlife.
Shrieks of shock come from the first 5 rows of people as they are doused in water. Tilikum, the 12,000 pound orca who measures in at a whopping 22 feet in length, jumps into the air on command and splashes the crowd who has paid a hefty price to sit and enjoy the show. It was certainly not the first show Tilikum and his trainer, Dawn Brancheau, had done together. To the crowd’s horror though, it would be the last. While going through the routine during their show on February 24, 2010, something seemed to be wrong. Mid-act Tilikum grabbed Dawn’s arm and ponytail and pulled her underneath the water. After having many bones broken and sustaining many life threatening injuries, Dawn was drowned to death by Tilikum in his tank with a live audience
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
Fishery Scientist are constantly working on ways to protect shark species and reduce shark bite incidences. Others have proposed that sonar waves are placed on nets to try and keep sharks away. Researchers are also collecting data from the sharks that are caught by the fishermen to be in a position to better understand sharks, and how we can live in unity with them. A shark tagging programme to try to better understand shark movements and patterns could also assist instead of culling. Statistics show us that there have been drastic reductions in fatal shark bites since nets have been installed in NSW and Qld.
One of the governments main reasons for culling the sharks is because they are coming in too close to the shores and becoming a potential threat to swimmers. But why is this happening? This is due to a change in shark feeding habits, but because they are eating more human of course not! Rather because us humans are over fishing and eliminating the fish/food sources of which sharks normally feed on. This is forcing sharks to come in closer to find food. Us as humans have forced sharks to come in closer and are now killing sharks because of our a...
As the great Sir David Attenborough would say “The great barrier reef is in grave danger” and everything that comes out of his mouth is in fact a fact.
[Transition: Let’s start by examining the cost benefits of exploring the ocean instead of outer space]
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.
Information (sub-point): Shark finning also has also drastically negatively affected the entire shark population. According to SharkSavers.org, “Shark populations face the threat of extinction in every part of the world primarily due to overfishing driven by the high demand for shark fins” (SharkSavers, 2013). It is also found that the global shark population has decreased by a drastic 90% over the last 50 years, and if change does not occur quickly, the entire shark population could potentially disappear
The first groups/people that I have chose that are for shark culling are the Western Australian Government including WA premier Colin Barnett and a lady called Krystle Westwood. The reason KryColin Barnett and the Western Australian Government wants to cull sharks is because innocent civilians are being scared, harrassed and potentially bitten and killed by sharks at local crowded beaches. One of the main jobs that the Western Australian Government has to do is to keep their people safe, and if their people are in danger they will do almost anything in order to keep them safe. Aswell as this, shark signtings, shark attacks and news about deaths from shark attacks can catch onto the news and travel around Australia and sometimes the world. This news
Hundreds of people, who get in the ocean every year, are almost none that encounter sharks. Even if you're lucky enough to see a shark big enough to bite you, you're much likely to die from a heart attack than getting bit by one. Shark attacks are mistakes and the idea of a shark off every beach waiting for people to come in the water is completely untrue. I will inform you on the background knowledge of sharks and the reasons why humans should not be afraid only aware.
