With the gap increasing, the conditions of the water have become hazardous for the Polar bears, making it harder for them to journey across. “A female polar bear reportedly swam for nine days - nonstop-across the Beaufort Sea before reaching an ice floe, costing her 22 percent of her weight and her cub” (PolarBearsInternational, n.d.). Nine days –nonstop is too much swimming for a Polar Bear, and in no way good for her health. In the process of swimming for those nine days she lost almost 1/4th of her body weight, which won’t be easy for her to gain back, and her cub. According to
As the ice continues to melt, some polar bears are drowning because they have to swim longer distances to reach the ice sheets. The U.S. Geological Survey has predicted that two-thirds of today’s polar bear population will be gone by 2050 due to the melting of the Arctic ice cap (New England Aquarium, 2013; USGS, 2007). Researchers of the U.S. Fish and Wildlife Service said, “Without enough sea ice, the bears’ disappearance probably take place as young cubs failed to survive to adulthood and females were unable to reproduce successfully” (Zabarenko, 2013). Animals that live on ice are not the only ones who affected by global warming.
Global warming and starvation are the only competitors for polar bears in the arctic. Mother nature is an impossible competitor to defeat, but one you must work and adapt to. Polar bears are begging the battle to adapt with mother nature, but will they be able to survive the fight is the question.

Other affected countries include the U.S. (Alaska), Greenland, Russia, and Norway (the Svalbard archipelago) .There are solutions to slow down global warming but unless we all act together, then there is no hope for the polar bear inhabitants of earth. CAUSES OF THE PROBLEM Polar bears are endangered animals as a result of the humans polluting their environment. Human hobbies such as hunting destroy polar bear population. Some cultures find polar bears as good sources of food. But, the leading reason behind polar bears endangerment is global warming.
However, this runs the risk of starvation as traditional prey are found in the ocean and not on land. As mentioned before, one of the two threats to polar bears are other polar bears as male bears may prey on cubs in times of starvation. Moreover, as the ice melts, humans take that as a signal that a new ocean has risen and thus there is an opportunity of industrial development. Such development can include petroleum exploration – however, a single oil spill in the Arctic would prove detrimental for not only polar bears but the entire ecosystem below them. As these “new oceans” arise, there has been more human movement and shipping around the Arctic.
Scientists believe that they would be able to survive in the short run but after a few years of not being able to live on the ice they would die. Polar bears dying will completely change the ecosystems that they live in ... ... middle of paper ... ...I would have thought that the average temperature would have raised much more in order to have all of theses negative affects. Rising temperatures in an area of ice and snow is especially bad. This is because ice and snow reflect most of the suns rays while water absorbs most of the rays.
Scientists have discovered that animals the live at the North Pole have recently became in grave danger. Mostly the polar bear because of the ice caps are melting giving it less land to live on (NRDC, 2008). If we do not do to slow down global warming, this marvelous bear will only be found in zoos by 2050 (NRDC, 2008). The hot dry weather will lead to other disasters like wild fires (Dye, 2013). The record was broke in 2006 with the total close to 100,000 wild fires destroying almost ten million acres (Dye, 2013).

Marine and terrestrial fauna at the earth’s polar regions are negatively impacted by global climate change due to the increase in temperatures most of which are now listed as endangered species due to the destruction of their habitat and alteration of their food web. The earth’s polar regions are the ice-covered areas located at the northern and southern ends of the globe known as the Arctic and Antarctica respectively. Life in these regions are incredibly difficult thus there are few and specific species living there. The north pole; the Arctic is affected most by the increasing temperatures as it has been proven to be heating up twice as fast as the rest of the world. This heat is therefore resulting in the melting of the ice.
An observant over the past years show the sudden increase of polar bears being endangered. The polar bear is a meat-eating bear, which normally lives within the Arctic Circle, surrounding sea. Polar bears are threatened directly on how humans treat our earth and our environment involving Global warming and greenhouse gas emissions. A friendly environment helps saving the lives of Polar bears that are being harmed due to our actions. This problem may be solved through various ways by helping to find ways to slow down global warming and to help regulate oil and gas businesses from using certain type of harmful chemicals that harm the Polar Bears and decreasing the rate of hunting being used to kill the polar bears prey.
