“In the animal kingdom, the rule is, eat or be eaten,..” Stated by Thomas Szasz. The animals live in a way where if they are not on the top of the food chain, they live in fear and worry that they may be eaten. In the article Dread is vanishing from the animal world. Here’s why that's a bad thing, by Sarah Kaplan, she explains how we as humans are leading top predators to go extinct or come close to. Sarah states, “the largest predators are dying out and no longer a threat smaller animals feel more secure and nature is thrown off balance,” The small animals live in fear, so when they go out for food, they don’t look long because they are always on the lookout for predators. When the smaller animals realize there is no danger, they eat more, …show more content…
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. Beaver marshes where otters, mink, muskrats and ducks could nest,” Bring back a predator that we took away in the first place had a huge positive effect on the land and animals around it. Having the top predators is the best way to go, they were placed on the earth for a reason and who are we to take that away. In conclusion, if we continue to kill of animals as we are doing now, the next 10 years will change horrifically. As Anthony Froude says, “Wild animals never kill for sport. Man is the only one to whom the torture and death of his fellow creatures is amusing in
In general, all the predators and prey (regardless of habitat) began with the same amount of population. For instance, there are a total of six predators (2 had forks, 2 had spoons, and 2 had knives)—regardless of habitat, Meaning each predator contributed to 33% of the population (Tables 1A, 2A). For prey, each bean contributed 25% of the population (Tables 1B, 2B). However, as generation progressed, differences began to appear.
Sixty years after the extirpation of wolves in the Northern Rockies and Great Plains of America, biologist and ecologist in Yellowstone National Park reintroduced wolves into a declining ecosystem that once thrived during their presence. The reintroduction brought immense controversy into the West and continues to stir outrage among anti-wolf groups. These anti-wolf supporters argue wolves are ruthless predators that cause destruction to natural environments and livestock. Conversely wolf advocates and scientists suggest that wolves are a keystone species that are essential to the natural regulation of our Western ecosystems. Although pro and anti-wolf advocates can agree that wolves have an effect on livestock, ungulate populations and ecosystems,
In the editorial by Ron Judd titled “Why returning grizzlies to the North Cascades is the right thing to do” found on the Seattle Times’ website, Mr. Rudd states his case for the reintroduction of Grizzly bears into the North Cascade Mountains of Washington State. He makes the argument that fatal interactions between hikers and bears are not a valid argument against reintroduction because the rarity of these encounters and the rarity of aggressive bears. He also cites some of his personal experiences encountering these animals and both his own and their reaction. Mr. Rudd uses this information to paint a picture that the bears are not as dangerous as commonly believed, using as an example the presence of grizzly bears in Yellowstone National Park which sees many more visitors than the North Cascades. Another point that Rudd discusses is his belief that bears are an important part of the wilderness experience, he shares his feelings after one of those encounters: “With senses heightened off the charts, it was as if I had stopped observing the natural world, and for the first time, stepped all the way into it.
This also shows how hunting doesn’t just cause extinction, but also makes an area less protective. The protaganists made sure that people such as Drake McBride and Jimmy Lee Bayless should always be avoided in the wilderness. Even though some of the animals are dangerous, they taught us that anyone should have some type of shelter no matter what the cause
Today otters face other threats. Apart from disease epidemics, otters continue to be threatened by overharvest, interactions with fisheries (e.g. gear entanglements), oil spills and being prey to killer
“I recalled passages from settlers’ diaries which mentioned the huge flocks of waterfowl, so thick that to hunt them they simply startled the birds into flight and fired randomly into the air, bringing down ducks and geese with every shotgun blast. Where had these uncountable thousands of birds lived and why weren’t they around anymore?” There are a lot of hunters in the Umpqua area, specifically waterfowl huntsman. If they are familiar at all with the history of waterfowl population, they have most likely known about the overpopulation that existed many years ago. Heilman uses a smooth, informative tone to teach readers about the wildlife populations and
“Thou shouldst eat to live; not live to eat”, is a famous quote by the well known philosopher Socrates, who believed this is the perspective we should take when we are eating food. Unfortunately, the times have changed and so has the way we eat. We no longer have to go hunting for our food, or grow crops to receive all of our fruits and vegetables. Because we have become a society that has grown into the new world of technology, there would be no need to rely on ourselves for what we need-- we can simply gather our resources from other people. In the book, “The Omnivore’s Dilemma”, written by Michael Pollan, takes us on a journey full of concerns of the “Food Industrial Complex”.
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 First, the reading claims that there were known sources of pollution along the Alaskan coast. However, the professor refutes this pint by saying that the pollution theory is weakened by that no dead sea otters were washed up to the shore. She said thet if the infection is the cause of the decline, there should be a lot of killed otters washed up, so this fact is consistent with the predation theory because if the sear otters were killedby predetors, they would not wash up to the shore.
This is why wolves need to stay on the island to control the biotic community and environment. As you can see, wolves are an important factor in the health of Isle Royale. Without them the whole island could perish. That’s why we can’t let them become extinct from the island. In conclusion, new wolves need to be brought to Isle Royale in order to repair the balance of the ecosystem and the overall well-being of the
The majority of people wanted to exterminate Gray Wolves because they were very frightened of them, and because the wolves ate farmer’s domestic livestock. The desire to exterminate was strong until interest in environmental conservation took place in the 1960s and 1970s. As study into environmental conservation developed, scientists discovered without wolves present in Yellowstone to hunt and kill prey, the elk started to overpopulate. Overpopulation was a problem because the elk were eating all the young willow trees. Overconsumption of willow trees affected the habitat of many other animals and plants in harmful ways; therefore, the ecosystem became unbalanced.
The successful return of sea otters on North America’s west coast Though the Gold Rush of 1849 is considered one of California’s significant historical events, the Californian Fur Rush is much overlooked in Pacific America’s history. Dating as far back as 1741, the Californian and Alaskan coasts were targeted by American, English, Spanish, French and Russian fur traders harvesting the warm pelts of the sea otter, fur seal, beaver, river otter, marten, fisher, mink, fox, weasel, and harbor seal. Sea otters (Enhydra lutris) were particularly overhunted and their populations suffered serious fragmentation up the west coast, coming dangerously close to eradication in this area (Estes, 1990). This essay will discuss the history of their decline
Due to the fact that only Native Americans were in the Oregon Territory, and they used animal products efficiently and did not hunt unless it was necessary, the animal population was very high. The main animal hunted by trappers were beavers. Their fur had become a commodity due to the near extinction of the creature from over hunting. “The possibility of profiting from the western beaver trade had led,”(McNeese OL) many to the territory in search of wealth and fame.
Introduction Predation is a biological interaction between two organisms of different species in a community in which one acts as a predator and captures and feeds on the other, the prey. Predator-prey relationships keep animal populations in balance. When prey populations increase more food is available for predators, and they increase in number as well. An increase in predators triggers a decrease in prey populations. As prey populations decrease predator populations soon follow as their food supply diminishes.
Eating meat is beneficial to humanity, because they provide nourishment that cannot be obtained from other sources. Without the support of animals, humans lack a distinctive diet, that is essential to their well-being. However, since animals are so important to the diet, they deserve great care and respect as well. Humans were always hunters and gathers. They always knew that meat was a big source of protein that helped keep them going(Araki).
Killing Animals In the present, the world has changed in many sides. One of changing is numbers of killing animals are increasing continuous. Many people think what are reasons for this acting?
