The eat snow goose eggs before they hatched

The first journal provided data that climate change causes the changes on Polar bears interns of their food. Snow goose in Hudson Bay have their nesting period prior to polar bears arriving time. However, losing ice brought their arriving time in ashore forward. Thus, it is overlapping the nesting period of snow goose. Therefore, weary polar bears from their long swimming journey eat snow goose eggs before they hatched seals. This can help Polar bear to survive in some stages and also stabilize the population (Rockwell and Gormezano 2010). The second journal indicated that they projected that losing sea ice will impact on losing polar bear’s habits as melting ice is on around of ice pack where the polar bears prefer to live. It is obvious that reduction of ice leaded to losing polar bear habits. However, it does not mean their population is also reduced due to losing ice as it is seasonal and only impacts specific bears and habits. In addition, the Western Hudson Bay in Canada is still considered as rich environment for polar bear, therefore, will have the greatest likelihood of population in the future (Durner et al. 2009).

 

Analyzing all the evidences provided from journal articles indicate that losing ice will affect not only their population but also their food and habits changes. According to Kives (2010), polar bears are in lack of food so that their population will decline as they cannot store their body mass. However, in the research conducted by Rockwell and Gormezano (2010) suggested that other food resource like goose eggs plays an important role in surviving of polar bears. Also, although climate change effected their habits, they projected that more polar bears will be in Hudson Bay where is the rich environment for polar bears. These evidences indicate that even though the message in newspaper, there are other impact on stabilize the population of polar bear.
