Rhetorical Analysis Of Big Fish In Troubled Waters

The controversial documentary Blackfish, directed by Gabriela Cowperthwaite rose to popularity four years ago in 2013, when it was released. Blackfish tells the stories of killer whales, or orcas, that were caught and kept in captivity, and the effects that arose due to their capture. The documentary focuses on Tilikum, an orca caught in 1983, who was kept in captivity in SeaWorld Orlando since his capture for 34 years. Blackfish does an excellent job in using all three rhetorical appeals, providing many real life examples and statistics, to defend their argument that orcas should never be captured or held in captivity.

On May 30th of 2012, judge Ken Welsch issued a ruling on OSHA vs. SeaWorld: During the shows, SeaWorld trainers must now remain behind barriers, separated from the orcas. The ruling on this case is necessary to keep trainers, audiences and as well as the orca safe. In the documentary “Blackfish” clarifies the incidents of SeaWorld, specifically with Tilikum a male orca, utilizing various rhetorical devices. The documentary declares the intelligence orcas have, the controversy with keeping them in captivity and how poorly informed the trainers are of previous incidents.

The local animals population is decreasing because the Python snakes are eating them. According to the text, “With no natural predators, these eating machines appear to be wiping out huge numbers of opossums, raccoons, and bobcats, as well as many bird species." This supports that the local animal population is decreasing because the snakes are eating the animals since the python snake population is growing then the other animals population is decreasing. The more snakes

Not many people think about how immoral it is for us humans to take animals from the wild and hold them captive for entertainment. Captive animals are often deprived of everything that is natural and important to them, and they experience captivity-related health problems as a result.

The earliest accounts of overfishing occurred in the 1800s, when the demand of whale blubber nearly wiped out the whale populations. In the mid 1900s, the harvesting of Atlantic cod, herring, and California sardines drove them to the brink of extinction. These high disruptions cause regional depletions of animal resources which is starting to cause a global problem. There has never been a more urgent time for fishing nations to make a commitment towards the sustainability of our oceans. More than 80% of the world’s fisheries have been, or are being pushed beyond their limits and are in dire need of strict management plans. Populations of fish and elasmobranch fish such as tuna, grouper and sharks have been declining to the point where the survival

The reading suggests that two possible causes: the environmental pollution and predators attacks. However, the lecture defends that is more probabily is the predators attacks.

In the listening passage, professor focuses on 1 effect of rapidely declining of sea otters in Alaska coast in North America has more affect. In the reading passage, 2 causes of this event are presented. One of them is pollotion that is made by chemical factories and also attacing predators such as seals, sea lions, and orca. The professor emphasis that attaching prdators has more effection on declining sea lion rather than pollotion. She has some reasons for supporting his oponion. First one is that there are a few chemical factories and also the amount of their pollotion is low therefore, pollotion has weak affect on death of sea otters. Second one is that the predator animals disappear due to their changing diet. Third one is that in some

Modern fishing methods have first and foremost created serious problems for ocean ecosystems. Scholastic Scope states, “The populations of almost all fish species that we eat have shrunken, some drastically, as a result of overfishing, or catching fish faster than they can reproduce” (Dignan 14). Sadly, fish cannot reproduce fast enough to sustain their populations when different fishing techniques drain their ecosystem’s health. Because humans are relatively new organisms, fish, a much older species, have not adapted to modern fishing techniques and overfishing in the sea. Therefore, oceans are at risk because fish cannot compete with newer, more efficient fishing techniques produced by humans. Climate change is furthermore another major threat to oceans. As published by Scholastic Scope, “Warming ocean waters, rising sea levels, and violent storms disrupt the lives of many species and affect fragile marine ecosystems” (Dignan 14). Although climate change may now be a controversial issue, its footprint and effects have no doubt left their mark. Powerful and destructive climate change has also been the culprit of extinction for many other animals such as the marine animals during the Permian-Triassic extinction event. Since things often repeat itself in history, the ocean could have a Holocene extinction event, which would completely

The article states, “…there is ample evidence that overfishing is a significant factor in the decline of numerous species and fisheries…” (Allan et al. 1045). This statement alone summarizes the article accurately and illuminates the major problem addressed in the scholarly journal. While relaying an indistinguishable message, an article by Myers and Worm finds a different way of relaying information.

First, the article states that pollution of ocean by industrial chemicals, oil rings caused to decrease otters' population. Otters cannot survive polluted ocean since their resistance ability cannot afford it. So, they died because of pollution. In contrast, the professor believes that pollution should kill other spicies in the ocean. However, population of other spicies is stable. Furthermore, there is no evidence that ocean is polluted. If ocean had been polluted, there would be huge effect on

The lecture indicated that the rapid decline in sea ottor number is contriputed to predators like Orca. The professor mentions that Orca hunt and eat sea otters. Therefore, no sea otters bodies are washed out in large number. If there is water pollution, sea otters bodies should be wahed out along the coast line in larg number. Thus, this why the professor refute the water pollution hyposize.

The Atlantic cod fishery collapse left terrible ecological consequences. As mentioned above, the fishing technology was a major destruction to the ecological system by using deployment and draggers. The huge nets that were dropped and dragged along the bottom of the ocean destroyed the underlying eco-system in the process. The effect of selective fishing on spawning grounds – that is, selectively over-exploiting one species in an ecosystem – had disastrous effect on the feeding relationships in that ecosystem. This contributes to the overall reduction of spawning stock biomass of the targeted species, but also an increase in the number of invertebrate and vertebrate predators such as crustacean and fish which will prey on cod eggs, larvae, and younger fish. It is a little wonder that a species like cod, would eventually run into difficulties struggling to survive when its habitat is being continuously destroyed and the balance of their food chain had been wiped out.

Third, the reading avers that uneven pattern of sea otters population is a clear evidence of pollution effect on their lives. However, the lecture supports a contradictory view as compared to that presented in the reading; it contends that the reduction has taken place in especial locations. Orcas are large predators so they cannot access to the locations where are shallow and rocky. Also, the reduction is tangible in deep locations, not the shallow ones. Hence, it is more probable that the reduction may be caused by large predators, instead of

In order for there to be plenty of fish in the years ahead, fisheries will have to develop sustainable fisheries and some will have to close. Due to the constant increase in the human population, the oceans have been overfished with a resulting decline of fish crucial to the economy and communities of the world. The control of the world's fisheries is a controversial subject, as they cannot produce enough to satisfy the demand, especially when there aren't enough fish left to breed in healthy ecosystems. Scientists are often in the role of fisheries managers and must regulate the amount of fishing in the oceans, a position not popular with those who have to make a living fishing ever decreasing populations.

According to the United Nations, 17% of fish stocks worldwide are currently overexploited; 52% are fully exploited; and 7% are depleted. This means that only an estimated 20% of worldwide fish stocks are not already at or above their capacity(Seafarms, 2013). Catches of Pacific herring have decreased by 71% since the 1960s, with Atlantic herring catches falling by 63%. Atlantic Cod catches have fallen by 69% in the same time(Seafarms, 2013). These are just a few of many facts and statistics on the topic of overfishing. The effects of these statistics and facts impact people’s and animal's lives around the
