The Dangers Of The Polar Bear

The Polar bear lives in the artic and uses the area’s costal waters and ice sheets. They are well equipped to live in this environment because they have a thick coat which serves as an insulator. They mainly prey on seals but have also been known to consume dead whales. They can grow to be 7.25 to 8 feet tall and can weigh around 900 to 1,600 pounds. Polar bears are a keystone species, if their numbers decrease there is a possibility that the seal populations will increase which could be devastating for crustaceans and fish. They help keep populations in balance.

The polar bear species is very unique when it comes to where, and how it lives. Living mainly in places such as The United States, Canada, Greenland, Norway, and Russia. Polar bears have elongated necks and smaller heads, black skin, and white fur. Every part of their outside bodies are covered in fur except for their noses and mouths. They typically over 1,000 pounds. Females are much smaller

The melting sea ice is also affecting the polar bear's main prey, seals, forcing the bears to turn to alternate, less nutritious food sources. Once sea ice forms in the winter, seals use the ice to create dens to give birth to their pups. In these months, polar bears use sea ice as their hunting grounds to find seal dens. Now that Seasonal Ice is forming later and melting earlier (IPCC, 2013), seals have less time to build dens and give birth. Consequently, polar bears have less time to hunt their preferred prey of seal pups. They must spend more time on land hunting other animals of less nutritional value. Organizations like Sea World Parks have reported male polar bears occasionally eating newly-born polar bear cubs because they cannot find other food to eat. Lack of nutritional food leads to a reduced body size. Polar bears are becoming thinner and weaker from not eating enough (Rode, Amstrup, & Regehr 2010). They have to swim longer distances to find ice to hunt upon, causing many cubs to die because they are not yet strong enough. In the Hudson Bay, the average polar bear weight has decreased by 15% and the population has decreased by 20% (National Wildlife Federation). In the summer when there is no ice, polar bears in the Hudson Bay go onto land to fast until the ice reforms. Now that ice is

Polar bears are the top predator in the tundra biome. The polar bear mainly eats seals. Polar bears are the largest land carnivore on earth, their average weight is 990 for males, and 500 for females. Polar bears have white fur, but black skin. The black skin is used to absorb sunlight for warmth, while the white fur is used for camouflage.

Some of the food that these seals eat include arctic cod, plankton, and crustaceans. The eat many different kinds of fish, they

Their feet are made for the ice and snow; they have rough leather pads so they don’t slip on ice, fur between toes and sharp claws as a weapon. They are plantigrade and left handed. Their toes are webbed so they can swim in water. Their fur is a yellowish white; the top lay is long and hollow to absorb heat and can float in the water. The undercoat covers their black skin that has four inches of blubber, which is an extra layer of warmth. This kind of coat makes it uncomfortable for polar bears to be in the heat. A polar bears sense of smell is the best sense they have, they mostly rely on it. It can smell a dead whale 15 miles away, can smell where a seal is hiding in six inches of ice, and can smell a human before they could even see them. Their eyes are small to block out the sun reflecting off the snow and their ears are small, close to their heads to keep warm.

The Polar Bear are found on the icy coasts that surrounds the North Poles and as far south as Hudson Bay. Around 60%of Polar Bears can be found in Canada with the remainings throughout Greenland, Alaska, Svalbard, and Russia where tend to be close to the ocean across the icy fields. The habitats are affected by human encroachment by hunting , and releasing chemical pollutants into the water.The Polar Bear eats Seals, Walrus, and Seabirds. Polar Bears can live up to 20-30 year. Polar Bears have a lot of fur and their fur is clear, white, or yellow. The Polar Bear is 6.5 ft-8.3ft. they can weigh up to 330lbs -1,322lbs and they can swim up to 25mph.

According to Polar Bears International, currently the polar bear population varies from 20 to 25 thousand of individuals.

Each species of bear eat certain foods more than other bears." (Alina Bradford) During summer bears can eat a whole day to fatten up for hibernation. Bear's diets depends on what food is available for the season. Since there's a lot of plants and animals, bears can have enough food and they even eat grass. "

The polar bear lives up in the Arctic region where global warming and climate change are melting the ice caps that the bears thrive on. They use the ice as a platform from hunting and rest. The random pocket holes in the ice, where the seals pop up at, is where the polar bear catches its prey. With this reduction of ice, “the abundance of seals, and increases the amount of energy and time needed for hunting, leaving less energy for reproduction” (Endangered Species and Habitats).

Ice bear was born in the Arctic. It is a very cold place. He did not have any parents and it made him sad. His parents have died because they got shot by a hunter He found some friends who have a mom and dad. They fed him fish and made him relax. He needed somewhere to live in the snow because he wouldn’t survive in the snow by himself. He built his own igloo. He grows up and he is happy.

A polar bear is one the most well adapted animals to its environment. They are very advance at hunting for prey like seals. Polar bears have white fur that can be used to be camoflauged when hunting for food, for its children and itself. Polar bears rarely ever seen when ever they are hunting for prey. Although polar bears need to eat a lot of food per day to be able to survive properly. The white fur can also be used to hide from predators. Polar bears could easily avoid predators with their fur and if they're seen they could also flee. Polar bears run can pretty fast on land but if they we're in the water they're a bot slow. Polar bears are great swimmers, it's just that they don't swim very fast. All polar bears need is a male and a female

One of the astonishing things about a polar bear that not many people know is that a polar bear's flesh color is black for the main reason of soaking up sunlight, providing warmth, while the fur is transparent and holds no color. The reason that the polar bears fur appears to be white is that the snow reflects off the clear hairs giving it a white or yellowish tint. The body shape is unique compared to other bears because they have longer necks and heads followed with a slender body. They are they largest land carnivore with females standing

Polar bears in the artic have been a topic of conversation and an area of concern amongst the media, the government and the Inuit people. The effects of climate change are being witnessed within the artic bodies of water. Ice in the artic is beginning to melt which is resulting in a loss of sea ice habitat. As a result polar bears have been listed as a ‘Species of Special Concern’. Though polar bears have been placed on this list by the government, the Inuit who have social, cultural and economic significance to this species do not believe in supporting this listing. With many stakeholders involved, each investor has taken a specific stance to what they see to be the utmost benefit to the environment, the species of concern, and what they
