Polar bears are considered one of the cutest animals in the world and are adored by thousands of people. Not only are they adorable, but they are also going extinct because of the warming temperatures in the Arctic. But what mankind does not know is that warmer climate isn’t the only thing killing off these animals; it’s truly cannibalism. This surprising truth is revealed in a similar way in Rod Sterling's short story, “Monsters Are Due On Maple Street.” The story takes place in an ordinary neighborhood that is supposedly being attacked by aliens.
Have you ever wondered why particularly in Alaska, bears need to stock up on food before winter comes? all the bears particularly in Alaska, need to stock up on food before winter comes because when winter hits food goes away. In the text it states " When the cold Alaskan winter hits, the bears’ food supply disappears. Temperatures drop, freezing the streams where tasty salmon swim. The berries that the bears snack on vanishes".
This has been happening to the polar bears for years and eventually no polar bears will have a home due to careless humans contributing to global warming. If humans continue to live our lives the way we do, a harmful impact will be left on the polar species. The visual is trying to display the aftermath of how the way humans choose to live their lives will leave a lasting impact on the polar bears. The setting in the visual
It is an important issue and needs to be tackled as it could put humankind and other biotic factors at risk. This issue is important to the Canadian society, as our animal species are at great risk due to global warming. Endangered animals such as the polar bear have a high change of disappearing in the wilderness if the ice caps continue melting as a result of global warming. According to experts, the Arctic sea ice is liquefying at a rate of more that 9% each year, destroying polar bear habits and putting their lives at risk. Greenhouse gases such as carbon dioxide and nitrous oxide form a layer in our atmosphere.
As a consequence, these animals are now forced to spend more time on shore scavenging for food, often going without while awaiting new ice to form in the fall. There is also growing concern for polar bear cubs that are thought to be incapable of swimming the increasingly greater distances in open water between shrinking ice floes. As evidence, they offer the growing number of very young polar bear carcasses that they notice being washed up on shore. Many mother bears also appear to be dangerously thin and less able to fend for themselves and their young. This situation is quite noticeable among polar bears along the western shore of Hudson Bay, especially around the town of Churchill Manitoba, a location where polar bears traditionally spend the late months of fall foraging on shore awaiting the freeze-up, a freeze-up that now comes later each year.
Otherwise it will cause repeated troubles with their living system. Habitats started to loss. Food supply became polluted. No matter how fierce looking these grizzly bears, their population has still started to drop gradually. Grizzly bears used to be peaceful, but they are easy to become angered if they are provoked.
Characters are the source of messages that help to reveal the meaning in any text. There are many differences in the male characters in the play Romeo and Juliet by William Shakespeare. All the male characters have differences and similarities. Romeo and Paris have a different view of love for Juliet. Tybalt and Benvolio both react differently to the feud.
It is harder for the inuits to catch animals. The ice is melting and making it unsafe for the inuits. They cant survive without food. Global warming is making unsafe conditions changing their lifes. They are having limited amount of food.
The amount of arctic sea ice is declining more than ever. Polar bears are being greatly affected by the decreases in sea ice. (Doc A) This is affecting their diet because without enough sea ice it has been very difficult for them to catch seals to eat. Also, their population is decreasing due to the longer periods between hunts.
The adaptations of bears have changed drastically due to hunting or habitat loss and sometimes captured for performances because of aggressive behavior and destruction of personal crops. The adaptions alter the way these eight species of bears grow and prosper. The development of their physical, dietary, and population has opposed how bears should really advance as group. Like all animals, black bears exhibit specific adaptations that help them survive in their habitats.
Studies have shown that there has been a decrease in freezing during the cold season and an increase in the thawing of permafrost, which suggests that more permafrost is melting seasonally instead of staying permanently frozen. Therefore, if a warming climate leads to the melting of permafrost, then the organic matter in it thaws out and decays, releasing the
Why was it an important field of study? It was an important field of study because people in the region was really concerned about the bear problem. The author’s hypothesis was that anthropogenic food would be a major component of the bear’s diet; the anthropogenic food would be lower in seasons with higher natural
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
One of the main reasons polar bears are going extinct is because they aren’t getting the right amount of food they need to survive. Seals, the main food source for the polar bears, are animals that depend largely on the algae that grows on the ice of the Arctic. With the ice content slowly depleting, there isn’t enough seals to sustain the polar bear population. One of the
Several factors may me directly or indirectly responsible for the declining numbers of the Canada's arctic region deer, and examining various evidences is necessary to find the reason for their reducing population. Increase in arctic area population leading to increased hunting may be a factor for the reducing arctic deer numbers. Also due to melting of sea ice may have affected the plants in the region. An increased number of other predators may also be the reason for reducing arctic deers, thus the purported decline may not be because of difficulty following the migration patterns.
