The polar bear (Ursus maritimus) is a carnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is a large bear, approximately the same size as the omnivorous Kodiak bear (Ursus arctos middendorffi).[3] A boar (adult male) weighs around 350–700 kg (770–1,540 lb),[4] while a sow (adult female) is about half that size. Although it is the sister species of the brown bear,[5] it has evolved to occupy

oceans, the Arctic is the smallest and shallowest. It is completely covered with ice during the winter, and remains mostly covered during the summer. Despite the frigid and seemingly lifeless conditions, this area holds a wealth of life, and an entire ecosystem thrives off of this body of water. While a few animals live on the land near the Arctic, the real ecosystem exists beneath the water, as many marine creatures such as jellyfish, walruses, fish, and even whales, live off of what the Arctic has to

Adding to that, the Arctic Circle barely has any vegetation to start with so if there are no predators to decrease the population of herbivores in that area, the vegetation would go to zero, killing the other herbivores or forcing them to move habitats. “Since seals create breathing holes, in about 100 to 200 years this will break up the ice and split the Arctic Circle.”(copied as it is from https://prezi.com/tyxt6p5q7l uz/facts-about-pol

affected due to climate change and Global Warming, as says the Wildlife technical report(Michelle Allsopp, 2012). The healthy breeding of Polar bears relies greatly on the Arctic’s ice covered waters and cultivate Arctic Wildlife, as well. Polar bears are the most precious habitats of Arctic wildlife, Not only because they are limited in numbers but also on the grounds that the specie have now endangered for conservation. According to authentic information(Michelle Allsopp, 2012), a female Polar bears

that these bears share 4 physiological stages including hibernation, walking hibernation, normal activity, and hyperphagia, however the polar bear is the only sister species that only females are known to hibernate. Polar bears are found only in the Arctic and feed mainly on seals and face many problems with global warming. Brown and black bears are known to have a wider habitat range, as they are land dwellers and do not need an open ocean near by as a food source. The presence of hibernation-induction

There are two types of species that treat their young differently. One of them raising their young to thrive despite challenges. The other, killing them off or never equipping them with the skills to survive. In Antarctica, Weddell seals are born in the harshest environment on earth. It is the coldest, windiest, and driest place in the world, made up of 98% ice and 2% rock. In a span of three years, one female Weddell seal gives birth to two pups on the isolated, icy shore of Antarctica. The mother

The Arctic region is one of the last frontiers to allow for the expansion of multiple nations and provides economic opportunities that have global strategic implications. The loss of 13 percent of its ice per decade has opened possibilities in new shipping routes, natural resources, fishing grounds, and destination tourism. The expansion of possibilities in the Arctic region has US National Security Interest implications, particularly the protection of energy resources and in maritime sea travel

polar bears are good swimmers there has been an alarming increase of polar bears drowning. Although they are well adapted to water, and can swim hundreds of miles to reach solid land, the distance to reach that land is increasing dramatically as the Arctic ice disappears. It is believed that fewer and smaller ice floes and erratic climate changes have contributed to this situation. Polar bears travel great distances in search of prey, which consists mainly of seals. The most important habitats for polar
