Polar Bears: Species Of Special Concern

In the overview section the author mentions polar bears can weight from 800 to 1,300 pounds and can measure 6 to 9 feet of length. Also, polar bear population is 20,000 to 25,000, and their habitats are Polar Regions. Mentioning these statistics has a purpose behind it, which is to provide the audience general factual information about the animal before the problem is presented. The WWF website has different approaches when it comes to using the logical appeal. Using images as evidence to support statements is one of the most notable approaches of the WWF website. On the overview section there is an image of the Arctic Basin Map shown, used as demonstration of where the 19 subpopulations of the animal are located across the

The inuit have to understand the natural patterns of Arctic wildlife because of global warming. Global warming is causing problems because the number

"Polar Bears, Ringed Seals, and the Complex Consequences of Climate Change" is an article written by Mary Bates who earned her PhD studying Bat echolocation. She works for an American Association for the Advancement of Science. In this article Mary talks about how Climate change is impacting different species at different rates. Here, she focuses on sea-ice dependent animals such as Polar Bears and Ringed Seals at Arctic. She explains on how these animals are dependent upon the sea-ice for living. The Arctic is warming at a rate three times greater than the global average, and that the sea ice coverage is declining rapidly. She also talks about Hamilton's study on sea-ice dependent animals. Before the melting of sea ice the Polar bears used

Polar bears are one of the countless species who are endangered. They were one of the first animals affected by global warming and their population is heavily decreasing. Around 1980, the Arctic was as large as 8 million square kilometres. In 2011, studies show that the Arctic has reduced its size to 4.5 million square kilometers. In the future, will there be anything such as the Arctic? Scientist predict by 2040, only a fringe of ice will remain in Northeast Canada and Northern Greenland. This is known as the Last Ice Area. This matter is mostly taking part in Canada, since; Canada holds more than half the world’s polar bear population. Other affected countries include the U.S. (Alaska), Greenland,

With the ever rising global temperatures, melting ice caps, and constant warnings about global warming, it is no wonder that the animals inhabiting the artic regions around the world are now suffering a decline in their habitat as well as their livelihood. Such is the case with the Polar Bears who may soon be gone in a scant few years.

Canada is home to many species of rich heritage, cultural significance and meaning to the Canadian people. Of the many species, one holds a strong iconic significance that plays a vital role in the very ecosystem it resides in. The polar bear species are undoubtedly the apex predator of its food chain and a culturally significant species to the indigenous people. With both these traits, it makes the polar bear a true Canadian symbol which is further emphasized by its very place on the Canadian two-dollar coin to the strength and endurance represented by this majestic species. However, no matter how strong and enduring the polar bears are to the arctic, such resilience is not as effective against the harsh changes their environment has gone through.

For the past few weeks, we have been reading the informational text, Where Do Polar Bears Live? Today, you are going to take an assessment where you will have the opportunity to show what you have learned. There are two parts to the assessment. The first part is a 1 short response question, and the second part is 5 multiple choice questions.

In 2008 the bears were listed by the U.S. Endangered Species Act due to global warming (1). This listing happened because of the ongoing loss of critical habitat for polar bears survival. The arctic sea ice sheets are the primary habitat for the bear. The bear lives, and hunts exclusively on these arctic ice sheets. Increasing global temperatures in the world’s oceans are shrinking the arctic ice for longer periods of time during the late summer months, leaving polar bears with limited hunting and breeding

The polar bear lives up in the Arctic region where global warming and climate change are melting the ice caps that the bears thrive on. They use the ice as a platform from hunting and rest. The random pocket holes in the ice, where the seals pop up at, is where the polar bear catches its prey. With this reduction of ice, “the abundance of seals, and increases the amount of energy and time needed for hunting, leaving less energy for reproduction” (Endangered Species and Habitats).

One of the most pressing issues for the Inuit people today would be the deterioration of their land due to extreme climate change. Warmer climates mean melting ice caps, rising sea levels, and the changing of animal’s migration patterns. The rapid retreat of the sea ice that has defined the Arctic’s ecosystem for thousands of years is threatening the existence and movements

The Arctic ice is slowly melting away and this is really hurting the polar bear population. This weather change is causing the polar bears to have a big diet change. They are now catching less seals but they are traveling a greater distance across the ice. This means they are not gaining a lot of energy even though they are using a lot by moving long distances. Researchers used collars with cameras and a GPS inside of it to find more detail on how polar bears are behaving and what they have to do to survive.

It contains an expanse of tundra with many marshes and lagoons with rivers situated between foothills of the Brooks Range and the wide, icy waters of the Beaufort Sea. Environmentalists said that this area “is the most biologically productive part of the Arctic Refuge for wildlife and is the center if wildlife activity.” The importance of these resources is not measurable. The Arctic is home to such animals as caribou, polar bears, grizzly bears, musk oxen, whales, wolves and snow geese. This area is full of wildflowers and contains water of excellent, unpolluted quality and quantity. The Arctic Ocean costal plain is an area critical to the survival of many birds and mammals (‘Alaska Wild’).

The research that the articles converse about relate to how Bears changes what Alaska means to us in regards to being an unchangeable wilderness to a wilderness that is changing due to climate change. This idea of a wilderness changing is also supported in Philip D. Martin’s report of wildlife response to environmental change. He claims that understanding the response of wildlife to climate change requires, “improved understanding of physical and ecological processes, as well as enhanced knowledge of natural history and population.” Regardless of whether it is because of warming temperatures, shrinking resources, or human development each of these theorists believe that there is a certain cause of climate change in Alaska.

Using the film and their theories, Bears shows the possible outcomes of Climate Change in Alaska and on the bears, and how they affect the other. Michael Carey emphasizes the idea that people once thought of Alaska as an “unchanging, eternal face,” but now consider it the “center of national and international climate change discussion.” Monika P. Calef treated Alaska’s Climate Change and what Bears portrays from a vegetation perspective, claiming that with the decrease of tundra areas due to Climate Change, forested areas were growing due to Alaska’s warmer temperatures, as well as causing other habitats to change and give other resources. Lowell H. Suring with his ideas of human impact related that other environmental factors influenced the “availability of important foods” for bears. Each of these articles relates to how Bears change what Alaska means to us as an unchangeable wilderness to a wilderness that is changing due to Climate Change. In addition, Bears means to us that Climate Change will not only change the life of the Alaskan bears, but it will change the lives of those who are also in our environment and any others in the future that come after

Polar bears are endangered because of humans over-hunting, and destroying there habitats. They are also harmed by humans because of over-hunting. These animals are very upset with humans and scared of humans because of, of them ruining there homes. Those animals need support/help, these animals need someone that is going to feed them, They also need a new home because us humans are destroying there homes. These animals have baby’s that need homes to survive.
