Firstly, the deers search for food in areas warm enough to sustain plants, but cold enough for ice to cover the sea, for their migration. The climatic changes because of global warming may have affected the plants and other vegetation in the Canadian Arctic. The plants which were food for the deers may have been destroyed by the unfavorable conditions, resulting from the global warming. Along with it, due to decreasing
Some individuals believe that using the wilderness for drilling of oil purposes will solve the US and its dependency on foreign oil. Through this article, Democratic congressman Edward J. Markey, alongside Representative Nancy Johnson, discuss the reasons for which they want to save the Arctic National Wildlife Refuge, or the ANWR, and other wilderness reserves from being developed on and industrialized. This wildlife reserve has been labeled as being one of the most magnificent reserves found in America. Unfortunately, people want to encroach on this territory and use it to increase the nation’s oil and gas development. This is not the first time that the reserve has been threatened but it is the most extreme.
This essay will be discussing how bears prepare themselves for the hard times of their life and why. Once the winter months start to roll around food gets scarce and it is hard for them to eat so instead of staying awake and starve themselves, they hibernate. In order to prepare themselves for this difficult time of year, the bears must create a safe shelter, gain a few extra pounds, and drink almost three times the amount of water as usual. Black bears are located all throughout the United States and they all have different ways of preparation depending on their environment. (Reference.com)
The argument about the dwindling deer population makes incorrect assumptions based on perfunctory findings. Until more information regarding the actual and previous population of the deers, scientific investigation of the cause of these supposed deaths, or the effects of global warming are obtained; the argument fails to make a coherent case to implicate global warming. The primary assumption that the argument makes are that the reports from the local hunters are accurate. While there is no reason to believe that the hunters purposefully botched the data, this information should be used as a precursor for a more thorough investigation.
The article states that there is a rapid decline in the population of sea otters, the mammals found along the coast of California to Alaska. The article claims that the reason for the declination is because of environmental pollution and provides two reasons of support. However, the speaker refutes that the dwindling is due to predation. First, the reading claims that environmental pollution is the most likely cause because oil rigs found along the coast cause pollution to a greater extent.
Climate shows that the future of the parks berries in the ecosystem is dropping. Elk is another which is are also expected to further decline due to climate-driven deterioration in forage conditions. Life for grizzly bears will get worse threw out time with more conflicts that will end up with dead bears. In the article it stated “Even the Fish and Wildlife Service has admitted that the primary post-delisting management plan, the Conservation Strategy, cannot actually regulate anything. And this agency has fiercely resisted any mechanism to relist bears if the population crashes in the face of excessive
Polar Bear Why is your world melting? , much like my idea, relies on fact and looks at how the habitat of the polar bear is disappearing. However in this book, the writing is impaired by its accuracy and the narrative does not read well. My focus is to find a balance between fact and description such as we can see in Ice Bear, though my diary is for an older audience. Ice Bear is also structured to follow the journey of a polar bear, leaving sensitive subjects such as hunting seals till the second half of the book so that the reader has time to understand why such things happen.
Although there is inconsistencies in the bear's body temperature the bear's body temperature is still changing. As seen in The Graph you can obviously see the body temperature going down during the winter (January-March) , when they're hibernating, and back up in the spring (April - `June). For the differences, for example - bears aren’t in a deep sleep. Although they aren’t in a deep sleep like most animals, bears sometimes wake up during hibernation to get a drink if they are dehydrated. So, they wake up because they have to if they don’t want to die of dehydration (Video) .
There are eight kinds of species of bears in the world and the two main common ones that are better known to people are the Grizzly bears and the Polar bears. Both bears live in North America yet live far apart from each other. Although the two bears are similar in many ways they both have very different environments, food sources, living behaviors and body features which include proportions from their body to their claws; many people will learn what makes each bear distinctly unique. Why are polar bears much larger than Grizzly Bears? How are the bears similar?
Richard Bosman created an woodcut called the Polar Bear II in 1981, and then thirteen years later, another polar bear image was engraved by Joseph Hecht, called the Sleeping Polar Bear. In Hecht’s engraving, he created an every minimal piece, while Boseman created a very detailed piece. Although both artists used a similar subject matter, polar bears, they each created an image which related it own story by their methods, materials, and treatments of each of the pieces. Boseman evokes a nightmarish look to his image with white lines on a black background, and a mostly obscured mountain scene with the bear covering most of the image. He also used the nonsensical to create the mood with a man entering the bear’s mouth with a paddle.
Polar Bears Have Natural Heating Ability The arctic circle is a cold and unforgiving wasteland, to live there you have to able to regulate your body temperature. According to Polar Bears International, polar bears are built for these harsh environments. Polar bears are animals that have to face this tough environment every single day of their lives. The polar bear uses many ways to insulate its body from the inside to the outside.
They love to eat meat and berries, including fish, rabbits, and blueberries. They both have razor sharp teeth and claws. The grizzly and the polar bear both have very soft fur that keeps them warm in the winter. They both are excellent swimmers. Polar bears live in snowy areas while the grizzly bear lives in forest’.
The biggest threat to polar bears is global temperatures rising. They rely on sea ice to catch prey, to migrate, to procreate, and to rest. They are currently endangered and scientists have discovered that if global temperatures do not decrease, polar bears will go extinct. Due to these rising temperatures, polar bears are struggling to cope with these new changes in their environment because they are so ice-dependent. Scientists are trying to save the last of the ice because this is how they hunt for seals.
So after taking a dip in the water, the bears just shake of the water. Underneath all that hair is actually black skin that absorbs heat from the sun. Those adaptions are what keeps the polar bear species alive today. These bears hunt for their food and use the freezing water to get to some of their prey. To assist with swimming, they have a four inch layer of blubber that lets them stay bouyont.
Grizzly bear is a kind of animal which has no predators, except for humans. Nowadays, If grizzly bear hunting should be allowed has became a controversial topic. To some extent, I agree with this point of view. In this essay, I will analyze some reasons that why I agree to stop hunting grizzly bear to a certain extent. The prohibition of hunting grizzly bear can be of assistance to the ecological balance.
