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.
Polar bears have created at series of adaptations such as their coats, paws, and feeding patterns to help combat the subzero temperatures. Reproducing is necessary for a species to survive. Polar bears have learned the most efficient method for raising their young in the artic environment. They serve as the main predator for many of the artic animals, but their only predators carry a different caliber. Global warming and starvation are the only competitors for polar bears in the arctic.
Restoring Wolves to Yellowstone In his book, Never Cry Wolf, Farley Mowat tells an Inuit tale, saying that in the beginning, caribou were created for humans to hunt. However, humans “hunted only the big, fat caribou, for they had no wish to kill the weak and the small and the sick,” creating a weak population of caribou. The creator then made wolves to eat the sick, weak, and small caribou, creating a natural health and balance to the earth (124). Humans have traditionally seen wolves as a competitor and a danger, but these misconceptions can now be put to rest. Because wolves regulate the carrying capacity, preserve the health of herds, and complete the ecological cycle in a balanced system, they must be restored to Yellowstone.
Over 200,000 years ago, glaciers covered much of the earth. Hungry brown bears, probably isolated in the glaciers near Siberia and looking for something to eat, discovered seals. The first bears probably just ate seal carcasses that washed ashore because that was their hunting capability at the time. Within 75,000 years (a short period in evolutionary time), rapid changes took place so bears could survive on ice, be an aggressive hunter and reproduce in a frigid land. That new species, the early polar bear, arrived during the mid-Pleistocene period.
Drill can destroy habitats; disrupt animal life force people to give up their traditional way of living their lives. However, Alaska has a very poor economy and drilling there would create jobs and help to bring money back to the area. I was a congressman from Alaska I would be weighing my options, I would do a thorough study of the lands and after that I would allow small portions of drilling for oil in Alaska’s Arctic National Wildlife Refuge (ANWR). Moreover, I would be making periodic assessments of every drilling area. If indeed there is a fact proven that oil development harms local wildlife, I will then conduct re-assessment of the ANWR drilling.

When a bear climbs on an ice floe, it shakes itself off because it is trying to prevent ice from forming on its fur (22-23). Because of climate change and hunting of polar bears are now becoming an endangered species which is affecting the food chain. We can fix this by going green, banning polar bear hunting and keep creating these new hybrid bears that are mixed with griz... ... middle of paper ... ... pushing grizzlies north. This summer marked the most drastic melting of Arctic sea ice to date. Biologists fear that this will promote the development of hybrids.
The climate change endangers the species, so much so that the animals have become one of the icons that conservationists use to illustrate the threat posed by climate change (The Huffington Post, 2014). You cannot protect a species from the impacts of climate change without addressing the issue of climate change, itself (Defenders of Wildlife, 2013). Large carnivores are extreme indicators of ecosystem health (WWF, n.d.). “As the Arctic sea ice melts, the polar bears lose their primary hunting ground — not to mention their most plentiful and nutritious prey. It remains a question whether they will be able to adapt to changing conditions and survive” (The Huffington Post, 2014).
The Endangered Species Act was established in 1973 to protect endangered species. Climate change, caused by anthropogenic greenhouse gas emissions, has serious consequences for many species, but it is a great concern for polar bears. Polar bear populations are susceptible to climate change, hunting, and habitat alteration. They are the world’s largest terrestrial carnivore and because of their strength polar bears are the symbol of the Arctic. Their physical characteristics make polar bears a perfect fit for the arctic.
According to Polar Bear International a study found from satellite pictures starting from the 1900s to now show major sea ice loss. Our greenhouse gases are affecting the polar bears habitat they breed and live off. When the weathers warmer, the ice melts. The loss of ice causes polar bears to prey on land. Some are left in the ocean trying to find ice and subsequently end up drowning.
