The author states that the pollution hypothesis seemed the most likely cause of otters decline along the Alaskan coast and provides three reasons. In contrast, the professor states that the ongiong investigation show that the predation theory is mst likely the cause of the decline and sh.e opposes each of the author 's reasons
Sadly, many Americans believe that losing the wolves would not be a bad thing for the prey’s sake, but in all reality losing the wolves would be devastating. One major thing that is present in all ecosystems, the place in which animals live, is a trophic cascade. A trophic cascade is explained in the essay as a “sequence of impacts down the food chain” (578). Hannibal gives the reader this example: “…In Wyoming’s Yellowstone National Park … wolves were virtually wiped out in the 1920’s and reintroduced in the ‘90s. Since the wolves have come back, scientists have noted an unexpected improvement in many of the park’s degraded stream areas”
Before I begin, I would like to let my viewers know that my credibility on the subject of captive orcas is not a professional one. I am merely someone who opposes the idea of captive orcas. I am also someone who has done some research and believes in the freedom and relocation of orcas to sea pens. For my persuasive project, I decided to create a piece of visual art to express my point. I want to show my audience, anyone on social media, the harsh life of an orca in places like Seaworld. My visual art is based on a meme called What People Think I Do/ What I Really Do. As you can see from my visual piece and other examples of this meme on the internet, this meme provides six different points of views from people on one subject. The points of views I used were of that of a friend, mother, an orca trainer, the CEO of Seaworld, and an orca. Each view illustrates what a specific individual thinks the subject does based on the individual’s personality, relation, and view of the subject.
”Many say that the seals may be on their way to extinction even though studies show that is nearly impossible at this point in time. Personally I believe that seal hunting is good for multiple reasons in which I will explain in this essay. The first reason that I believe that seal hunting is good for not only the environment but the species itself is that seals are becoming over populated. When people hunt not only seals but other
Hammerhead sharks rarely attack humans. Only 17 atacked have happened in the last 450 years but none of the attacks were serious enough to be fatal.The animal i'm going to be comparing the hammerhead to is a bottlenose dolphin. The dolphin doesn't chew its food it just goes down the throat like a snakes.
Sarah wrote about an experiment that was tested in Yellowstone National Park, where grey wolves use to live. Over time they were either hunted or left. It was explained, “where grey wolves had been missing for decades before being reintroduced in the 1990s, showed that the presence of that single, irreplaceable predator set off a series of cascading positive effects in the environment. The elk that been preventing willows and aspen from taking root on the river bank were brought into check. Birds started roosting in the recovered trees, trout began swimming in the shady water beneath branches.
When the two sides come together, the argument boils down to one major point, should we “Free Willy?” Those who side with the whales, whether their reasons be emotional or defended with welfare standards, feel that the whales should be released back into the wild or into private coves3. The opposing side makes valid arguments against the release of the currently captive whales. Currently captive whales were either removed from the wild at a young age, albeit in a cruel way, or they were bred in captivity11. The point in discussing this issue is not to address the cruelty of taking an animal from the wild, or to argue whether or not breeding programs are successful or appropriate. What needs to be addressed regarding the release of captive whales is their survivability in the wild6. Many killer whales are bred in captivity now, and thus have depended on humans for the entirety of their lives7. If a captive bred whale were released into the wild, it is likely that he or she would approach humans which could be dangerous for both the human and the whale. Captive bred killer whales would also likely have difficulty hunting, as their food was always provided for them by humans.
Hammerhead Sharks protect themselves by swimming away from predators and attacking their predators. The Carnivores can outswim a sea creature and they will lose where the Hammerhead went. Even if another species can go as fast as a hammerhead shark, they will still escape. The hammerhead tries to stay away from where their predator was chasing them for some time and then returns if they need to. While swimming, they have very strong senses that can tell when something is getting near them. Their eyes on the side of their heads help them to look all around without fully turning their body. With the wider view of all around they can counter attack their predators attach.
Do you often hear things like "we are killing our planet" or "global warming is a massive problem" from your local hippies? I 'm sure you must accept the common misconception that humans have made a huge impact on climate change, well I beg to differ: humans are actually not the main reason to climate change. In this essay I will explain as to why climate change isn 't caused by humans and why you should change your perspective on the topic. By analyzing that Global warming is natural, sea levels have been steadily rising for thousands of years, and CO2 has little impact on global warming, it becomes obvious that climate change was not cause by humans.
The Clatsop Indians were great fish-eaters, and loved to eat sea animals. After discovering a 105 feet long whale, blubber became a tasty addition to their diet. Lewis, Clark, and I were friendly with the Mandan tribe, but didn’t like the Clatsop Indians because the Clatsop were used to traders and drove a hard bargain. We exchanged some goods, including a sea otter pelt, for fishhooks and a small bag of Shoshone tobacco. The Clatsop tribe informed us that there was a good amount of elk on the south side of the
