As polar bear population decline so does the population of seals which is a fatal cycle for polar bears, because without ringed or bearded seals, polar bears cannot survive and will be pushed inland. The fallout from the bears being pushed onto the mainland could be detrimental to the Inuit population that are in coastal regions of the ice caps, as bears have been reported to be increasingly more aggressive with humans, it is only a matter of time before the interactions become fatal. Now, not only do they have to adapt to warmer weather, but they also have to deal with the diminishing of the land that they inhabit. Polar bears run the risk of becoming extinct, because without the large ice surfaces, they will have no place to live. It is largely believed that polar bears have adapted to new conditions once, and would have no problem doing so again, however this is utterly incorrect.
Polar bears are seen as being one of the most beautiful bears around the world. With their white coated fur, and have footpads that are like non-slip shoes (National Wildlife Federation 1). Polar bears have been around for over a million years, and are evolved from the brown bears which moved to the arctic area in the world. The reasons why polar bears matter are because they have a very important role in the marine environment, but to keep the marine environment healthy we need to keep these polar bears from going extinct. Polar bears are on the vulnerable stage of extinction, and they need to be taken off that list.
They are so hungry that they ruined someone’s apple orchard. Hibernating is very important to bears. Bears are coming into to towns and cities. It is definitely a big problem because bears are starving and coming to town and cities to find the food they need to hibernate. If they keep starving, they won't be able to hibernate, which means that they will keep coming to towns or cities.
This formed a suspicion that is climate change really threatening polar bears. Therefore, this paper will show that Global Warming has obvious and multiple impacts on the polar bears; in spite of many facts showing them being endangered, there are some people claiming of them being fine. Global Warming, a significant change in climate and temperature, is caused by accumulation of carbon in the
As the world we live in today continues to warm up, the problems surrounding the survival of the world’s beloved polar bear continues to grow. Over the past twenty years, we’ve seen a change in the number of polar bears in the Arctic and have witnessed a decrease of the amount of Arctic ice in the sea. Many scientist have come up with ideas to tackle the problem, but there hasn’t been a solution that has greatly influenced the predicament at hand. Ultimately, when discussing what to do about the endangered animals, it is valuable to consider what the species needs in order to remain; a healthy population and genetic diversity. Andrew Derocher, biologist at the University of Alberta, and the rest of his team have come up with a few ways to combat these needs.
The adaptations of bears have changed drastically due to hunting or habitat loss and sometimes captured for performances because of aggressive behavior and destruction of personal crops. The adaptions alter the way these eight species of bears grow and prosper. The development of their physical, dietary, and population has opposed how bears should really advance as group. Like all animals, black bears exhibit specific adaptations that help them survive in their habitats. Black bears are scientifically classified in the order Carnivora because they have canine teeth.
Introduction: Due to moving the arctic snow fox to the tropical rainforest, the snow fox will experience tremendous amount of evolutionary impact. So due to speciation, the formation of a new species due to evolution, it will be called a Forest Fox. The Arctic Snow Foxes environment is very frigid. They feed on the weakest of animals, and even feed of of the leftovers of other animals like polar bears. One of its predators is a polar bear, but because of its white fur, it is very hard to spot.
In today’s world, Earth is getting warmer every year. With each year going by, scientists have more data to prove global warming is becoming more of a threat. The greenhouse effect and pollution is contributing to the temperature rise and is causing the polar ice caps to melt. A side effect of the melting, the water will flow into the oceans causing sea levels to rise and putting coastal cities in danger. As global temperatures and sea levels rise, there is only so much humans can do to slow down the process and to maybe even make it stop as a whole.
For awhile, global warming has become more recent and changing the planet and the animals behaviors. So far, “Rapid climate change is already causing problems for living creatures all over the world. One problem is that weather changes are resulting in mismatches between two species that have traditionally depended on one another,” (Nakaya). Furthermore, climate change is causing more problems, that the animals are not doing their regular jobs that they are supposed to do. In addition, animals are acting unusual by coming out of hibernation to early, polar bears are thinner and less healthy, different species are moving north to get more cooler air, and some species are breeding days before they should.
There are many other species that are affected by it too. However, the species that are worst affected by glaciers melting are the species whose habitats are in cold and ice-covered regions. For this reason, polar bears and Antarctic penguins are in threatening situation because polar bears feed themselves by eating seals and other prey that they hunt on the ice and in the water. But now, their lives are threatened as the ice on which they need to hunt and feed is melting and they need to go somewhere else to find their food. (Bell) Krill are a major food source for penguins.
