Summary Polar bears are an important arctic species that is in danger from climate change. A keystone species, polar bears are essential for a balanced ecosystem in the Arctic Circle. As the overall temperature of the earth is increases due to global warming and the greenhouse effect, the sea ice that polar bears live on for most of their lives is disappearing. Polar bears require sea ice to survive, as it is their hunting grounds and habitat. When the ice melts, polar bears are forced to move closer to the pole. Unfortunately, polar bears use northern landmasses to reproduce, and access to these parts of the globe from the ice sheets is becoming more difficult for the bears. The bear’s main source of food the seals, are also negatively impacted by the loss of sea ice. Seals need the ice to have their young, and with less ice, seals are also disappearing. Some polar bears have been driven to cannibalism, further reducing their populations. While international treaties designed to limit …show more content…
Additionally polar bears have been approaching human settlements. Polar bears are carnivores that primarily eat seals. Polar bears walk on the sea ice and will eat ringed and bearded seals that come up on the ice. If there is no sea ice for the seals to come up to birth their young, then the polar bears will have to find another source of food, such as bird eggs (National Wildlife Federation, n.d.). Bird eggs do not provide enough energy for polar bears and therefore, the polar bears must consider earing each other (usually a weak, older or sick bear) in order to get enough energy to travel or nurse. Due to the lack of access to seals, polar bears are also approaching human settlements in search for food, and are a real and great safety risk for any human. Polar bears that approach the settlements could be shot down and harvested by

Research Paper On Polar Bears

Polar bears are one of the only bear species known as marine mammals. That is because polar bears have features that help them adapt to the arctic weather. Their black layer of skin under the white fluffy fur allow them to stay warm, and their wide webbed feet make it easier to balance on ice because their weight is spread and the web helps them not slip. Also, unlike other bears, polar bears are carnivores. They eat mostly seals and sometimes walruses, because those are the only abundant sources…

which live in the North and possess black fur have very low chances to survive, that is why most animals, including polar bears, seals possess white fur and can easily hide on the white background of snow. The color of skin and fur is very important for survival, because it enables animals to hide, protect themselves or hunt being undetected. We can write a Custom Research Paper on Evolution for you!

Nowadays, it seems like the world is getting warmer and things are not looking to pretty for the animals that are living in the wild. It is looking a lot worse for polar bears, monk seals, and salmon. Years ago it was expensive for biologist to get the data to see how much energy an animal wasted on catching his next meal .Luckily, that little device you see on someone when you are at the gym (known as accelerometers). Present the possible answers that scientist have been in search of for years.…
