Polar Bears in Danger
Oil explorations and oil spills are posing serious threats to polar species, resulting in severe risks to both marine and terrestrial ecosystems and wildlife. Polar bears, the chief predators in the Arctic marine ecosystem, are affected by exposure to oil followed by oil spills. Even though oil pollution and the ratio of spills in the Arctic are on a low level at present, during 1993 to 2007, many oil spill incidents were reported, most of which were the consequences of extreme collisions, groundings, and sinking accidents, leading to long-term consequences to polar species, and even a chance of extinction for polar bears. While there are no tested and operative

Polar bears are considered as the chief predators in Arctic marine ecosystems; they feed on the fat of ice-dependent seals. In order to cope in icy habitats, polar bears have a distinct set of characteristics. They have a thicker coat of hair than ordinary brown bears, which is blanketing even their feet to provide heat and grip on icy surface. A dense layer of fat (blubber) underneath their coat offers resilience and protection from harsh environmental conditions (“Fact Sheet-Polar Bear”). Oil leakages, on the other hand, occur from pipeline punctures, drainages or outflows, or transport mishaps. Studies examining the effect of oil exposure on polar bears indicate that upon petroleum or fuel exposure, polar bears absorb bulk of oil in their hairy coat. After the physical contact, polar bears can metabolize sufficient quantity of oil, causing kidney malfunction, digestive system imbalance, and brain diseases that lead to death. Removal of thick blanket of hair, and skin and eye irritations are few of the other harmful effects (“Polar bears and oil developments”). Species like polar bears and seals are able to absorb oil across their skin, via gastrointestinal tract, or by inhalation. Once absorbed, it spreads to all tissues in varying quantities. Both seals and cetaceans have an ability to digest oil components with the help of mixed function oxygenase supplement (Geraci & Aubin, n.p.), while physical contact and ingestion in polar bears leads to severe hematological and renal anomalies; together with associated pathological alterations (Engelhardt,

Climate Change In Nunavut
1039 Words | 5 PagesAs 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.

Polar Bears And Climate Change Essay
1262 Words | 6 PagesClimate 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
