Climate Change: The Decline Of Polar Bears

7: Problems and Threats:Due to global warming the tundra is starting to deplete and the biome known as tundra will be all water. Land animals cannot adapt to this so the artic fox and polar bear will be no more. Water level will be raised every where and floods could be critical to the entire

As the polar ice caps melt further toward the poles every summer, it makes the polar bears job of hunting and staying alive harder and then eventually, impossible. This creates an empty niche in the northern ecosystem. (Williams et. al. 2011) While making it difficult for the polar bears to hunt, shrinking ice caps make it easier for orcas to move further north and reach new food sources such as narwhal and seals. The implications of this new shift of the major predator in the region could be catastrophic. (Williams et. al. 2011) Food scarcity has always been a challenge for polar bears but now the challenge is even greater due to increased competition. (Williams et. al. 2011) Animals lower on the food chain will see a drastic decline in population due to the introduction of a new

Many different theories have been suggested to explain why the East Coast Fishery collapsed. A few examples include overfishing, destructive fishing practices, and changes in natural conditions. Primarily, overfishing plays a huge role in the collapse of the East Coast Fishery. The amount of catch allowed by the federal government was extensively high. Scientists may have overestimated the number of fish reaching adulthood each year, due to this more fish were caught then reached maturity. In addition, the collapse of the East Coast Fishery also revolves around the theory of destructive fishing practice. Many fishing practices can be extensively proficient at harvesting fish, but they often accidently catch non- target species, these species (also known as bycatch) are usually thrown/tossed away.

The book “The Weather Makers: The History and Future Impact of Climate Change” written by Tim Flanner pertains to predicting the global warming consequence on earth and species. In chapter 9, the unraveling world, the author talks about global warming and how it can have a long-lasting and far-reaching impact on our lives. He points out the substantial and rapid change of the climate and its connection with the effects of El Nino and La Nina are also uncovered. Climate change can be a major contributor as to where species live and how they interact. The changes can also be observed by the changing migration patterns of these species. Moreover, the unexpected changes in climate can also bring about a shift in the behaviour of species such as insects, butterflies, birds, caterpillars, frogs and possums. The author illustrates an example of how in northern Mexico and southern California the increased temperature has caused the plant on which caterpillars feed to wilt earlier which eventually cause larvae to starve.

Many, many animals are going endangered and even extinct because of human caused climate changing. One of those notable examples is the polar bears, which only have a population of 20,000-25,000. The reason polar bears are going extinct is because warmer temperatures in the north is causing the ice caps to melt more, and in the summer, polar bears use the ice caps to travel to get food after hibernating. But if the ice caps melt too much and break away, then polar bears

Attention Getter] Did you know that according to the National Park Service, in the mid 1970s the Greater Yellowstone region only inhabited about 136 grizzly bears (United States)?

As the world we live in today continues to warm up, the problems surrounding the survival of the world’s beloved polar bear continues to grow. Over the past twenty years, we’ve seen a change in the number of polar bears in the Arctic and have witnessed a decrease of the amount of Arctic ice in the sea. Many scientist have come up with ideas to tackle the problem, but there hasn’t been a solution that has greatly influenced the predicament at hand. Ultimately, when discussing what to do about the endangered animals, it is valuable to consider what the species needs in order to remain; a healthy population and genetic diversity. Andrew Derocher, biologist at the University of Alberta, and the rest of his team have come up with a few ways to combat these needs.

Climate change, specifically warmer temperatures, has extensively altered these habitats by reducing sea ice extent, thus affecting polar bears since they use it as a platform to travel, hunt, and rest. Changes in the timing of sea ice formation and break up limits the amount of time bears can feed off of seals during late and early summer, hence limiting the amount of fat they are able to store for later seasons. Lower rates of food intake and storage correlates to low reproductive rates, and since females do not have sufficient fat and mass required for successful parturition, they abstain from

Humans consider polar bears as one of the cutest animals on the planet. Not only are they adorable, but they are also going extinct because of the warming temperatures in the Arctic. But what the public does not know is that the warmer weather is not the only thing killing off these animals; it is truly cannibalism. Rod Sterling's story, "Monsters Are Due on Maple street," reveals this surprising truth in a similar way. The story takes place in an ordinary neighborhood that is supposedly being attacked by aliens. But Sterling is not writing about cute bears killing themselves, he is showing people aliens and space is not their enemy, but really themselves. Likewise, mankind’s worst foe is mankind itself.

There are 2 types of worms: worms that eat at night (nocturnal) and worms that eat during the day (diurnal). The birds eat during the day and seem to be eating ONLY the diurnal worms. The nocturnal worms are in their burrows during this time. Each spring when the worms reproduce, they have about 500 babies but only 100 of these 500 ever become old enough to reproduce.

The seal hunt should be banned. They are being hunted for their fur. Canada allows 470,000 seals to be hunted every year, and that is endangering the seals population. Hunters specifically look for baby seals to hunt. They do this because their fur is very soft, and they have a lot of value in them. The seals that get killed for their fur are all 2-3 weeks old. These animals are getting killed very often, and they get killed in a very painful way. Hunters don’t shoot the animal. Shooting the animal is much more effective and it will put it out of its misery faster, but hunters use clubs to beat them to death. Seals are being hunted, and it should be banned in Canada.

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.

A surprising amount of species have been completely wiped out directly from human interaction in recent history. One interesting example would be the California grizzly bear that ironically is completely extinct in California. According to the California State Library website, the California grizzly bear or Ursus Californicus became the official State Animal in 1953 after being extinct for nearly 20 years and is the centerpiece on the California flag. Extinction, the elimination of a species, is a normal process of the natural world. (Cunningham and Cunningham 232) However there is nothing normal or natural about the extinction of the California grizzly bear. Humans are solely responsible for its extinction. Without hunting regulations, Californians over hunted and quickly led the state animal to extinction. Without strict fish and game laws and equally strict enforcement, many species have been brought to extinction. As a result many laws and programs have been enacted to prevent extinctions of at risk species.

The stakeholders in this issue are environmental groups, such as Greenpeace, who firstly advocated for the ban on commercially fishing Pollock in Alaska, as well as the Federal government, who passed the legislature. Their actions have directly led to the endangerment of the Western stock stellar sea lion. Fortunately, they are also the precise people who can remedy the situation.

How does climate change affect Arctic animals? Climate change affects Arctic animals drastically by destroying their living habitat and food sources. Polar bears are having a hard time finding food because the ice caps are melting. They use the ice to rest on while hunting for seals, but since there is less ice it’s causing the polar bears to drown from exhaustion. Walruses can eat up to 200 pounds of clams each day. Clams are usually found near the continental shelf but with ice caps melting it is getting harder for walruses to find
