The Polar Bear is a huge and powerful animal, they are also the top predators in the Arctic and the world's largest land living carnivore. But sadly there is not so many of Polar Bears that live in the Arctic for it is found to be an endangered spies. Polar Bears are endangered/ threatened due to the burning fossil fuels such as coal and oil releasing high amounts of carbon dioxide into the atmosphere. Carbon dioxide is a greenhouse gas that traps the sun's energy and causes the Earth’s climate to get warmer. Without these greenhouse gases Earth would be too cold for life to survive, but the huge amount of carbon dioxide being release is all caused by human activates pushing the Earth's climate out of balance. This climate change has causes the Arctic’s temperature to almost rise twice as fast as the average global temperature. This has already effected the Arctic today. The ways these rising temperatures are affecting the polar bear by interfering with their habitats and there hunting in the sea. Due to this polar bears have to swim farther just to find ice platforms from which they...
Memories, with or without context, play a key role as plot devices in both Away from Her and “Bear Came Over the Mountain.” Used to provide context for their only semi-chronological story lines, memories in the story and movie alike give solid glimpses of the past that allow the plot to move forward. One of the most prominent memories, in both the story and the movie, and certainly the clearest of the latter, is the section in which Grant and Fiona go on a walk/ski in a park. The differences between the scene and the passage are substantial, ranging from difference in message to difference in visuals. This section is an excellent example of the drastic differences sometimes found in adaptations, and allows for the presentation of a case for
Lamarck’s ideas on polar bear evolution Lamarckism can be used to explain the evolution of polar bears from brown bears, specifically skin and fur color. Lamarck’s theory stipulated that a characteristic (brown or white fur color) which is used more by an organism will become stronger. One that is not used disappears eventually. Change occurs when polar bears want to change. If a polar bear’s phenotype changes during life in order to adapt its environment, those changes are passed onto its offspring.
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 Bull Moose" is a poem by one of the great Canadian poets, Alden Nowlan. It is a finely crafted poem by a very talented poet. It reminds us how far away from Nature the lives of ordinary men and women have strayed. This is something common to all of us who live so much our lives in buildings and who so rarely experience Nature in its raw form. Nowlan creates powerful layers of images, and contrasts them in a way to make us feel just how damaging to our minds and souls this separation from Nature has been. His poem is Romantic in the way it tries to remind us of how far we have fallen and how hollow our idea of progress is. Indeed, Nowlan suggests that we may be more of a beast than the moose.
The habitat of the Arctic wolf is a very harsh place. The temperature must be below zero degrees. There are tundra, rolling hills, glacier valleys, ice fields, shallow lakes, and green flatlands (Arctic/Antarctic: The Arctic Wolf). These snowy white creators don’t have that many places to live. Arctic wolves used to be everywhere in North America, but sadly now they are reduced to Canada, Alaska, Idaho, Michigan, Minnesota, Montana, Wisconsin, and Wyoming (Arctic/Antarctic: The Arctic Wolf). Arctic wolves are one of the most dangerous types of wolves; people need to find a way to save them and their habitat before they disappear forever.
This poem, Sarajevo Bear written by Walter Pavlich, addresses one of the most important themes, the struggle to keep humanity strong and stable. To begin with, this poem is discussing the sniping campaign that took place in Sarajevo in 1993 and how civilians were the targets of these attacks. During this time people faced a dilemma: they could either stay in hiding forever or until the war ended, or they could do something that would get their mind off the war and relieve some of their stress. People knew though the risk of leaving the security and safety of their home as they could be shot and killed at any time without warning. But still this did not stop the people working at the zoo and feeding the bear to stop their job. Furthermore, the first verse of this poem states that this is the last animal at the zoo. This illustrates that just as many people were dying, many animals were dying as well illustrating that our actions not only affect us but they also affect things around us, and in this poem it was the zoo animals. In a zoo the animals are contained within a certain area an...
* Perhaps the most noticeable and striking characteristics of a polar bear is its color. The fur shafts themselves are not white. The shafts actually lack pigmentation and are transparent which allows them to scatter and reflect light resulting in ideal camouflage in a world of ice and snow.
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).
The Arctic Tundra The Tundra is located in the northern regions of North America, Europe, Asia, and Africa. as well as a few regions of Antarctica. The Tundra is the second largest vegetation. zone in Canada. It can be divided into three different sections: the High Arctic Tundra, the Low Arctic Tundra and the Alpine Tundra.
For years, we have heard of the devastating effects of global warming and how the melting of the polar ice caps will cause severe climate changes. One animal that has suffered most from global warming is the polar bear. Global warming has caused the polar bear population to decrease due to the results of having to swim longer distances, loss of habitat, and lack of mates to reproduce offspring. Global warming has caused this species to become endangered and has some attention with social media. Global warming has caused much damage to the polar bear population due to the warming of their habitat.

What it looks like: Siberian tiger is the largest and most rare of all members of the cat family. This cat is 8-10 feet long, excluding their 25-38 inch rattling tail. This species of tiger weighs 400-700 pounds. Like all members of the tiger family, males are significantly larger than females.
The polar regions are most affected and vulnerable to the warming temperatures because the poles are covered in ice. The world’s ice sheets are melting faster than ever and temperatures in the Arctic region are rising twice as fast as anywhere else on Earth according to the NRDC. This will have a serious impact on people, wildlife and plants in that region. The National Climate Assessment has said that “By the year 2100, it 's estimated our oceans will be one to four feet higher, threatening coastal systems and low-lying areas, including entire island nations and the world 's largest cities, including New York, Los Angeles, and Miami as well as Mumbai, Sydney, and Rio de Janeiro”. Polar bears are in great threat as the ice sheets melt because they use the ice to travel across the land and hunt. As the sea-ice platforms move further apart, the swimming conditions become more dangerous. The U.S Geological Survey done by the National Wildlife Federation predicts that by the year 2050, two thirds of all polar bears will disappear. Researcher Bill Fraser has tracked the Adelie penguins in Antarctica and reported the numbers have fallen from 32,000 to only 11,000 over the last 30
The Bengal tiger is a carnivorous, mammal primarily from India. It lives in habitats such as the coniferous Himalayan Forest, the mangroves of the Sunderbans, the hills of the Indian Peninsula, or the forests of Rajasthan and Northern India. At one time Bengal tigers were scattered throughout Asia. Now they are generally found in India and some regions of Bangledesh, Bhutan, Nepal, and Myanmar. There is approximately 4,000 alive in the wild now, and about 300 are in captivity in zoos around the world.
Global warming is a serious problem with two major effects which are increasing in sea level and degradation of wild lives. Increase in sea level is affecting the entire landmass of the earth. According to NASA, the polar ice cap is melting at the alarming rate of nine percent per decade. Arctic ice thickness has decreased 40 percent since the 1960s (Oskin). The amount of water is more than the land in our planet. If this global warming continues at this pace, soon there will be no ground left on earth. The terrestrial animals will be exterminated from the earth if glo...
