    Hey, I didn’t see you there, how are you?I'm just wondering whether or not a big ol' grizzly bear is going to come charging at me at any point in my life, but seeing as grizzly bears are endangered that probably won't happen. In the past, there were thought to be around 50,000 grizzly bears in North America, nowadays they are growing sparse there are estimated to be only around 1800, now not even a 20th of the population in the past. Most of these grizzlies are located in Yellowstone National Park and Alaska, but they can also be found in Wyoming, Colorado, Idaho and Montana. Some are thought to be in Washington.

    To begin with, the melting of polar ice caps has caused polar bears to swim long distances. According to Bryan Walsh of TIME Magazine the melting of the ice caps have caused polar bears especially the young cubs to swim longer distances which has caused a “ forty-five percent mortality rate” (Walsh). In the article Walsh, writes about a study that showed that younger cubs because of low fat and strength were more likely to die due to the long di...

    Bears can live anywhere but Grizzly bears live in subalpine meadows and dense forests. When grizzly bears hibernate they usually live in caves. A sloth of bears is usually a mom and the cubs. The mom bear is called a sow, the dad bear doesn't have a name because they are never with the family and the babies are called cubs. There is usually a dearth amount of cubs in a family. The families are always together and not with a different family. All bear look different but I'm not talking about the other bears I am talking about grizzly bears. Grizzly bears are usually just the color brown and not really anything different. Grizzlys need big paws to get around and travel. Bears have small black eyes. Their eyes are small because they don't need very good eyesight because they have such good sniffers. Usually the weight of a cub is about 4- 10 pounds when they are born but when they are adults they weigh 175- 500 pounds.

    Grizzly bears are enormous bears; that, tend to be misunderstood by others. Many times, they are portrayed wrongly in movies and tv shows. People may go off by things they see; in the movies and immediately suggest that’s the way the grizzly bear is. If others took the time to find information on the grizzly they would see how wrong the movies are about them. For many people grizzly bears can be a mystery such as where they live, what they eat, and whether they hibernate or not. However, with a bit of research answers can be found.

  • Grizzly Bears in North America

    1791 Words  | 4 Pages

    The Grizzly bear (Ursus arctos) has long been considered to be the symbol of the wild. They are beautiful, powerful and at the same time vulnerable animals. They are known to survive in remote areas not inhabited by humans. The Grizzly was once able to occupy most of the land from northern Mexico to Alaska and most places in between. With a disappearing natural habitat and one of the lowest reproduction rate of any mammal in North America the Grizzly bear has seen population number fall dramatically. Most Grizzly bears left in the continental United States are located in four states near Yellowstone National Park. Canada has Grizzly populations in five provinces. The state of Alaska has the largest population of these amazing animals. With change in habitat due to human involvement and low reproduction rates, Grizzly bears have had a hard time sustaining population numbers. This has caused them to virtually become non-existent in certain areas of North America and is forcing the bears that are left to move to more sufficient areas that can sustain their populations.

  • Polar Bears: The Evolution Of The Polar Bear

    1500 Words  | 3 Pages

    Out of an Ice Age emerged one of our most majestic creatures in the world the polar bear. From its brown bear ancestry, the predator evolved to be a master of a harsh and unwelcoming ice kingdom. Intelligent, adaptable and fierce, the polar bear learned how to survive in a place that offers few comforts to any creature. But now that very environment is in flux. And so is the polar bear’s fate (Nature). Polar Bears are very different from other bears. Polar bears are very large bears compared to Black bears. Polar bears weigh anywhere between 330-1700lbs and Black bears weigh anywhere between 150-600lbs. They have strong legs with large, flattened feet with some webbing between their toes that help with walking on ice and swimming. The wide paws prevent sea ice from breaking by distributing weight while walking. Their paws allow them to pull a 600 pound seal out of its breathing hole (Rosing, 20). The webbed feet results in making polar bears, unlike other bear species to be considered as marine mammals along with seals, sea lions, walruses, whales and dolphins (Polar Bear). According to Rosing Polar bears are excellent swimmers and have been known to swim up to six miles an hour and as far as 60 miles at a stretch. The bears paddle with their front feet and steer with their back feet. They often overheat. Sometimes they venture into the waters just to cool off. When a bear climbs on an ice floe, it shakes itself off because it is trying to prevent ice from forming on its fur (22-23). Because of climate change and hunting of polar bears are now becoming an endangered species which is affecting the food chain. We can fix this by going green, banning polar bear hunting and keep creating these new hybrid bears that are mixed with griz...

  • Polar Bear: Threatened or Not?

    1595 Words  | 4 Pages

    In recent decades, the global warming threat has captured the attention of the nation and the world. While the main focus began with concentrating on the effects this long-term natural crisis would have on the human population, select groups have worked to approach the topic in a manner that entails prevention in order to help other animal and plant species around the globe. One such organization is the National Oceanic and Atmospheric Administration, which has played a major role in the conservation of the polar bear species, one of the mammals most adversely affected by the recent climate changes. As more research has been conducted regarding the polar bears, scientific name Ursus Maritimus, the conclusions have been shocking. In 2008, the Department to the Interior listed the polar bear species as “threatened” under the Endangered Species Act of 1973 awarding it some protections mandated by the federal government (Wolfe). However, on January 5, 2011, Representative Donald Young proposed a bill in Congress in order to delist the polar bears as threatened, thus decreasing and even removing the conservation efforts that have been set in place over the past three years. The polar bear Species should remain listed under the Endangered Species Act because ice thickness has decreased 40 percent during the past 30 years thus reducing the polar bears’ critical environment, if current conditions continue the polar bear populations around the world may decrease by two thirds by mid century, and since the species has been protected under the Endangered Species Act the worldwide populations have experienced stabilization or growth in most circumstances.

  • Polar Bears: The Speed Of Climate Change

    1330 Words  | 3 Pages

    Polar bears don't just live on ice, they use the ice as an advantage to catch prey such as seals. Polar bears have adapted to living on ice and being able to withstand the cold weather. Now that the climate is changing at a fast pace, polar bears are losing their land because its melting, leaving them with no place to walk, sleep and taking away their way of hunting prey. (polar bears international, 2015) This is all happening so fast that there is no way polar bears will be able to adapt to the new environments, causing extinction. The arctic is warming twice as fast as the rest of the world is due to the build up of greenhouse gases in the atmosphere, making it a problem happening very rapidly. (Bagley, 2015) Temperatures in the Arctic region have risen 7 degrees Fahrenheit over the last half century. (Bagley, 2015) Population among polar bears has decreased up to 40% in some areas. (Bagley, 2015) With the climate getting warmer, ice is melting earlier every spring, and takes longer to freeze every winter which is disrupting the feeding and breeding cycles of many different arctic species. (Bagley, 2015) Polar bears have adapted ways to survive in the cold harsh arctic environment including having the ability to cool down their outer skin to keep their vital organs warm when they are submerged in cold water. Though this may help the delay of hypothermia as they have to swim greater distances from ice shelf to ice shelf, that doesn't mean polar bears can swim forever. (Bagley, 2015) One bear that a scientist studied swam 500 miles over nine days, but lost 22% of her body weight, and lost her cub.(Bagley, 2015) Many different scientists have been studying the behaviour of the polar bear to see if it could adapt in any way to survive. Eight U.S scientists made a hypothesis consisting that polar bears could lower their metabolic rates enough to survive as food

    The one way to keep bears and humans safe and living in the same environment is learning to understand them and being able to tolerate them. If people don’t do these things theses beautiful animals will begin to decrease in numbers. While there are a lot of black bears in Alaska, an estimated 100,000, hunters believe that you can just hunt and hunt and the population will decrease to average, but the plans of some hunters seems just over the top of making these bears go on to the endangered species list. But with the help of people and cooperation the Black Bears will continue to live in Alaska.

  • The Arctic Region: Climate And Climate Change

    1676 Words  | 4 Pages

    The Arctic region is home to a variety of valuable animals and plants, including polar bear, seal, and so on. The ecosystem of the Arctic region is fragile because these animals are evolved to live in extreme conditions. With the climate change, many animals are endangered. Ice is the habitat of polar animals because they have to rely on sea ices for resting, food, and reproduction. With the climate change and the decrease of sea ice, the number of polar animals is decreasing and their health is threatened. For example, the average weight of female polar bears in 1980 was about 650 pounds, but the number reduced to about 500 pounds in 2004 (Djoghlaf 15). The earlier breakup and later condensation of sea ice shortens the hunting season of polar bears. Polar bears mainly feed on seals that indwell icy land. The melting ice reduces the number of seals and food intake of polar bears. In addition, polar bears are used to living in ice caves. The rising temperature causes the collapse of ice caves, which can kill baby bears. The climate change is negatively affecting the biodiversity in the region and will definitely harm the ecosystem

    The polar bear has a long, narrower head and nose, and small ears. The polar bear has coat that appears white but, each individual hair is actually a clear and hollow. This helps the polar bear keep warm. The polar bear's coat helps it blend in with its snowy surroundings, this adaptation helps the Polar Bear hide while hunting. The polar bear's front legs are slightly pigeon-toed, and fur covers the bottoms of its paws. These adaptations help the polar bear keep them from slipping on ice.
