...The polar bear (Ursus maritimus) is a carnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is a large bear, approximately the same size as the omnivorous Kodiak bear (Ursus arctos middendorffi).[3] A boar (adult male) weighs around 350–700 kg (770–1,540 lb),[4] while a sow (adult female) is about half that size. Although it is the sister species of the brown bear,[5] it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet.[6] Although most polar bears are born on land, they spend most of their time at sea. Their scientific name means "maritime bear", and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. The polar bear is classified as a vulnerable species, with eight of the nineteen polar bear subpopulations in decline.[7] For decades, large scale hunting raised international concern for the future of the species but populations rebounded after controls and quotas began to take effect.[citation needed] For thousands of years, the polar bear has been a key figure in the material, spiritual, and cultural life of Arctic indigenous peoples, and polar bears remain important in their...

...physiology to live in certain conditions. One of those animals is the polar bear who lives in the extreme cold temperatures of the Arctic. In figure F-1, shown are several features which helps the Polar bear adapt to environment minus a few which will be noted later. These amazing powerful creatures are one of the few mammals which have adapted to its marine environment. As seen in figure F-1, the polar bear has large feet. “To help protect their feet, there are pads on the bottom of them. They are designed to give them plenty of traction for walking on the slippery ice” (2011). The ground in the arctic is permanently frozen. In order for the polar bear to be able to walk on the ground and keep warm, they have these large padded feet to assist them in their living environment. These padded feet are also equipped with large claws which are used in hunting their prey. The polar bear's Latin name, ursus maritimus, means “sea bear” (2011). This animal is one of the few mammals which depends on it s marine environment for survival. As shown above in Figure F-1, the polar bear has short legs and large feet to allow them to propel through the water quickly. Because of these physiological features, the polar bear is able to catch its prey quickly and efficiently. Another interesting feature of the polar bear is its skin and fur. The above figure does not display this as one of the important features of the polar bear. “Its distinctive white coat acts as camouflage in the snow...

...Coke’s Polar Bears Coca Cola’s polar bear has been around for quite a long time, being introduced in a paper ad in France, 1922. The polar bear is a well-known symbol for Coke even though they portray the animal much different than it lives in the wild. It’s a symbol because an animated polar bear wouldn’t mean much to someone outside of our culture, but Coke has ingrained in our culture that it aligns with them. We created our infographic to display the benefits that both Coca Cola and the polar bears receive. Coke has done some great things for the polar bears but much more can be done. The polar bears have receive almost $2 million in support from the World Wildlife Fund (WWF). There has been a substantial reduction in deaths of polar bears from trying to uphold a section in the high Artic that the ice will last the longest. Certain surrounding tribes have also slowed down or even completely stopped killing polar bears. Coke has also alerted the public and since they are becoming aware they want to help. I added the picture of the three cubs laying on top of their mother to allude that the polar bears are happy and in stable conditions. Coke has garnered much public appeal since starting the campaign. They teamed up with WWF in 2011 and since then they have accomplished in reducing carbon emissions by 8.5%. The benefits they receive are substantial. The more people they bring onto the product, in turn their profits will increase profoundly. Even though coke has provided...

...The Tragedy of Polar Bears Polar bears in the Arctic are tremendously affected by pollution now. As global warming progresses, wind and water currents carry pollutants, most of which come from industrial sources in different parts of the world, and cause them to travel to the Arctic because of the ‘conveyor belt’ nature of the atmosphere and ocean (Yarim 2013). These chemicals accumulate in the fat of many animals, mainly through the food chain, which are then eaten by top predators such as polar bears. Thus, polar bears inevitably have severe health problems and risk death. When consumed at high levels, the pollutants can have a dramatic and potentially fatal impact, which affects the polar bear population in the Arctic severely. The most prevalent chemicals found in the Arctic are “Persistent Organic pollutants (POPs)”, such as the pesticide DDT, the industrial chemical polychlorinated biphenyls (PCBs), which can biomagnify up the food chain. Other pollutants may include acid rain, heavy metals and radioactive isotopes (Yarim 2013). According to studies, bears with high levels of some POPs have low levels of vitamin A, thyroid hormones, and some antibodies (WWF Global 2009). The pollutants load of polar bears in the Arctic are negatively affecting the immune system, hormone regulation, growth patterns, reproduction, and survival rates of polar bears. The studies have suggested that the immune system is weaker in some polar bears with higher levels of PCBs. A weakened...

...environmental article told from the perspective of a polar bear. Aimed towards a specific audience, this passage is intended for an ignorant population of people who are hurting the environment. Attempting to provoke guilt by giving the perspective of a polar bear on becoming extinct, so that the readers will be inspired to change their ways that have injured the global ecosystem is the purpose of the article. The overall tone of the passage is sympathetic, depressing, judgmental, angry, and upset. To begin, the writer integrates multiple anaphora and repetition to help enhance the article and to help enforce her ideas and to emphasize these beliefs. In the last paragraph, the polar bear repeats “you” multiple times. The employment of anaphora puts the blame of the polar bears dying, and the importance of saving the environment, on the reader. By doing this, the author relates back to her purpose of arousing a sensation of shame. As for repetition, throughout the passage, the author employs a particular expression...

...Polar Bears, the largest members of the Ursidae family, are bears that have transparent fur, which keeps them warm in icy and cold environments. They have large bodies, where male polar bears can weigh anywhere from 700 to 1,000 pounds, and female polar bears weighing anywhere from 300 to 700 pounds. While standing upright, they typically measure around 10 feet tall. Lengthwise, they measure around 7 to 8 feet long. The average lifespan of most polar bears ranges from 20 to 25 years. While they do appear as harmless majestic creatures, they are actually some of the most vicious hunters and carnivores out there. Furthermore, Polar bears have strong large legs with some webbing on their feet, making it easier to walk on ice as well as swim. Their...

...Imagine you are a polar bear, and you want to get to shore, but you can't because it's too long of a swim, because the ice caps at the shore have melted and the ice caps you are on our floating further and further away becauses of greenhouse gas effects on the environment. Therefore you can't get home, you can't get food, and you can't survive. The polar bear was added to the endangered animal list in 2008 because of multiple causes, most are from impacts caused by greenhouse gases. Greenhouse gases in Alaska and Northern Canada have three major Impacts on polar bears and their ecosystem: Greenhouse gases cause pollution in the ecosystem. They cause climate change in the ecosystem, melting the ice caps the polar bears live on, and lastly the greenhouse gases cause shorter hunting seasons, less food for the polar bears, and bad body conditions for polar bears, causing the polar bear population to go down....

...The Survival And Cubbing of Polar Bears The survival and cubbing of Polar bears is rapidly getting affected due to climate change and Global Warming, as says the Wildlife technical report(Michelle Allsopp, 2012). The healthy breeding of Polar bears relies greatly on the Arctic’s ice covered waters and cultivate Arctic Wildlife, as well. Polar bears are the most precious habitats of Arctic wildlife, Not only because they are limited in numbers but also on the grounds that the specie have now endangered for conservation. According to authentic information(Michelle Allsopp, 2012), a female Polar bears can only give birth to 1 to 3 cubs with in life time. Also, the mortality rate of infant cubs exceed from 70 %. Hence, there are less chances that the individuals of the Polar bears can be replaced by new generations. Furthermore, the other factors of climate change and global warming have intensified the threat to the species conservation due to climate changes in Arctic Wildlife. The projected claim can be justified with supporting observations presented below for reference. * Comprised survival rates of sub adult due to poor nutritions resulted from the sea ice breakup. * Inefficient reproduction cycle due to early spring ice breakup. * Deprived access to prey for sufficient...

...Polar Bears: WWF Polar bears are classified as marine animals because they spend most of their life on the ice from the Arctic Ocean. Their bodies are structured with layers of fat along with water resistant fur to stay warm in such cold, wet conditions. They spend about 50% of their time hunting for seals, which most of their diet consists of. Recently, the polar bear population has significantly declined due to climate change. Because of oil spills, the warming of the atmosphere and illegal hunting of the species, polar bears are now listed as an endangered species. The Worldwide Wildlife Fund is making efforts to increase polar bear population by decreasing human pollution, preventing conflict between humans and polar bears, and...

...Polar bears are known for their vibrant white coat of fur. They have adapted this beneficial trait to help them survive and it provides the polar bear with fitness in its environments.this trait makes the polar bear white and makes them blend in with those icy surroundings. The hairs on a polar bear aren't actually white but appear white and thats what helps them blend in here's how the fur looks white,the polar bears long outer hairs that protect their undercoat are transparent and the thinner hairs are colorless as well. This makes it appear white because of the air spaces.when it reflects the colors and the light it appears white on the polar bear. The trait helps the polar bear stay safe from predators, and makes it so they can sneak up...

...Polar Bears I did my favorite organism on Polar Bears. I chose this animal because it is very interesting on how they live and how they survive. The temperatures in the Arctic tundra vary from 50 degrees fahrenheit to -37 degrees fahrenheit. The diet of a Polar bear is a variety of different organism that live in the arctic tundra. But one thing the Polar bear likes the most is seals and bearded seals. I think that they eat this as their main source of food because they spend a lot of time in the water and the Polar bear is considered a marine animal. They are also known to eat walrus,beluga, and whale. I find it very interesting that they eat a whale considering how big whales can be. But when they cannot find any of the organism to eat they will go and eat some of the very few species of plants that grow in the arctic Tundra. The population of a polar bear is around 20,000-25,000 polar bears in the world. But one issue that is affecting the population is global warming and that is making the ice break up and warming the ocean and if there is no ice that means that there is no Polar bear....

The reason why is that you peskey humans are using up all of my water! If I don't have any water, that means that there is no water to freese into the ice that makes up my home. If I do not have room to live, that deffinitely means I don't have any room to hunt. If I do not have any place that I can hunt from, I can not get any food for my self, And do not forget, I allso have my cubs to feed as well. If my cubs do not get fed, they will most likley die. If my cubs die its only logical to belive that other cubs would die also.If all the cubs die, then my entire species would die as well. You do not...

...The Cause and Effects of Global Warming on the Polar Bear Most experts agree that global warming does exist and it is having a devastating effect on the Earth’s climate. A major concern of global warming is the melting of the polar ice caps. Research suggests that global warming is going to greatly impact the survival of the polar bear. In southern portions of their range, like Hudson Bay, Canada, there is no sea ice during the summer, and the polar bears must live on land until the Bay freezes in the fall, when they can once again hunt on the ice. While they are on land during the summer, the polar bears eat very little or sometimes nothing. In just 20 years the ice-free period in Hudson Bay has increased by an average of 20 days, thus cutting the polar bears' seal hunting season by nearly three weeks. Because the ice is freezing later in the fall, and melting earlier in the spring the bears have a much shorter timeframe in which to hunt during the critical season when seal pups are born. As a result, average bear weight has dropped by 15 percent, causing reproduction rates to decline. The Hudson Bay population is down more than 20 percent. Despite the fact that polar bears are good swimmers there has been an alarming increase of polar bears drowning. Although they are well adapted to water, and can swim hundreds of miles to reach solid land, the distance to reach that land is increasing dramatically as the Arctic ice disappears. It is believed that fewer and smaller ice floes...

...Arctic Home Campaign Coca- Cola Presented to Mutar Kent CEO and Chairman of the Coca-Cola Company March 8th 2012 March 8th, 2012 Muhtar Kent CEO and Chairman of the Coca-Cola Company Dear Mr. Kent, Although raising awareness for the polar bears habitat is critical, study has shown that the company’s campaign to save the polar bears by the changing the colour of the Coca-Cola cans has been ineffective. Many consumers were mislead by the change of colour of the cans. The new white Coca-Cola cans are too similar to the Diet Coke cans. In today’s society, consumers have been accustomed to brand recognition and do not take time to read labels. Many consumers accidently bought regular Coca-Cola thinking they were purchasing Diet Coke. The purpose of changing the cans to white is to promote awareness to the polar bears habitat and raise money for the cause. Many do not know how to donate to the campaign. It was unclear to many consumers the reason for changing the colour of the cans. The change brought more confusion than it did awareness to the polar bears. I am thankful for the 25 participants who gave me their time in order to complete the questionnaire survey, as well as Maria-Jose Errunza and my classmates of Comm 212 who have helped me with this report. Their contribution is greatly appreciated. Thank you for the attention given to this report. You may contact me at 438-886-8012 should you need further clarification in regards to...
