The Evolution of Polar Bears Laysa De La Torre Polar bears have a very interesting history as they are evolved from brown bears. It is very weird how they don’t hibernate but interesting to hear what happens when they don’t hibernate. Polar bears are actually very interesting even if you may not like them, you will soon be interested after reading this. Polar bears hair is white because, the air spaces in…

Many people think polar bears and black bears are the same but that is not true. Polar bears and black bears have many differences and some similarities. A polar bears weight is about 330 to 1500 pounds and a black bear can weigh 90 to 600 pounds. Their height is also different, a polar bear can be from 7 to 8.4 feet and a black bear can be 5 to 6 feet. Polar bears are found in circumpolar north in areas where they hunt their prey and black bears live in North America in the forest. Polar bears…

Ever since I was four years old, I have read books watched movies, and have heard out the breathtaking experiences in Alaska. Though I haven't been there, I know everything there is to know about this astonishing state. Polar bears and penguins, are some of the many animals I would dies to study and see up close. Their behavior and adaptations are unlike anything ever seen in this common state we know as home. The climate is like no other, except maybe Antarctica, the snow and ice surrounding…

mainly ringed and bearded seals located on the border of the Canadian arctic. Those seals are killed by polar bears during breathing holes depending on the availability of seals in the ecological niche (Stirling and Archibald 1977). However, arctic foxes and polar bears compete for the adults’ seals and the competition for food increase between them. It is not clear whether the polar bears feed with seals or are hunt by arctic foxes. If seals are not available, polar bears feed…

Sea Levels Rising Hurting Our Animals Polar bears are on the threatened species list because of global warming and sea levels rising. Millions of species aquatic and land animals are dying. Most under the sea ecosystems are severely affected by global warming which causes sea levels rising. For example, mangrove ecosystems require constant sea levels to survive. Sea levels are rising and affecting polar bears, sea turtles, and coral reefs. Polar bears are in jeopardy, becoming extinct…

live on is melting due to global warming. The population will continue to drop so long as we don’t do anything about it, and soon, no one will get to see the snow white bear. In 2012, about 1.32 million square miles, which is right around 24%, of the Arctic Ocean was froze over. That is low considering that it dropped about 3% since 2007. The heat will continue to increase causing the ice to melt completely. What would happen if all the ice would melt? First, as the ice melted, the sea levels…

According to the 2014 Arctic Report Card, there have been significant changes in sea ice extent. Specifically, the report addresses the slow but significant seasonal decline in sea ice cover. Arctic sea ice is of utmost importance for ecosystems to thrive. Post et al. (2013) discuss this further, stating “the sea-ice biome influences the abundance, distribution, seasonality, and interactions of marine and terrestrial species.” This is especially true for polar bear populations in the Arctic, as…

For many years people believed that the Polar Bear would be the first species that goes extinct due to climate change, however that may not be the case. The American Pika lives in the rocky mountain areas surrounding both the U.S and Canada. This distant cousin of the rabbit lives at elevations between 8,000 and 13,000 feet, and it makes its home in rock piles and slides. The reason why this creature suffers so much due to climate change is that of how they originally adapted to their…

considering the fact that even though people do know the negative impacts of the use of these chemicals, they still use it. The economic component in the selected issue is the that it costs a lot of money to transport the polar bears to the high Arctic, where they can find their last refuge due to the climate…

taking place in the Arctic, especially the physical changes resulting in challenges to Canada’s sovereignty. Sovereignty means the authority of a state to govern itself or another state. In today’s society, claiming sovereignty has become has become a major factor in causing international conflicts and disputes. To ensure security in this day and age, Canada’s government must continue pursue its jurisdiction over the Arctic, due to increased interest in the area. The attention the Arctic…
