Polar Bear numbers have been decreasing and will continue from 2001 to 2010 there was a drop of about 40% in their population. In the wild there is suspected to be roughly 25,000 left. This can be explained by climate change. The increase of temperature there is a decrease in their habitat size and has been causing some strange behaviors in the polar bears. Polar bears have been observed saving food for later by burying it in the snow. The main food source for polar bears are seals, they have…

When people hear about the Arctic Circle or Antarctica, the first thing that pops out are the polar bears, also known in the scientific community as Ursus maritimus. However, another word that appears in our minds is the North Pole, climate change, and most importantly, extinction. A terrestrial mammal mainly considered marine due to its necessity to be on the sea for many months was the center of attention for years. This iconic figure, part of the Ursidae family, started to be considered as a…

the article "Did you bring the bear spray dear?” published on Nov 17th of 2008 the author, Chris Selley interviews experts on bears and bear attacks and in order to know how common are black bear attacks and how to prevent them and how to act if someone finds himself or herself face to face with a black bear. Most bear attacks occur in natural environments rather than urban spaces and in North American only a small number of those attacks are lethal. Expert on bear attacks, Stephen Herrero, says…

if we say it is not. There is nowhere for the polar bear to go to because all of the ice is melted around him. This is a powerful photograph proving to people all around the world that it is happening. The sad part is, it only works on a small amount of people. We are so in tune with our lives that we feel sad for two minutes and the next we move on to the next thing. The composition of the artwork is a photograph. It is showing that the polar bear has nowhere to go. The photographer used a…

Polar bears are a species of bear these bears have a white fur that helps hide them in their habitat. Polar bears evolved one to three million years ago from the brown or grizzly bears. They are the only bear species to be marine mammals. The Polar bears habitat is being threatened by humans and Global Warming. Because their habitats are being threatened and scientist are working to stop global warming so, the animal in North pole can be saved this including the Polar bears. Polar bears have…

Seal and polar bear hunting have long since been a popular pastime and cultural practice for Canada’s indigenous populations. However, as outlined by the newspaper article “Greenpeace side sweeps the Inuit,” if not properly controlled, it can also lead these species to even further endangerment (Sopuck R., 2007). When caught, polar bears can often be sold for large sums and can provide a source of income for Indigenous groups (Sopuck R., 2007). While this practice has been a long-held cultural…

For many years people believed that the Polar Bear would be the first species that goes extinct due to climate change, however that may not be the case. The American Pika lives in the rocky mountain areas surrounding both the U.S and Canada. This distant cousin of the rabbit lives at elevations between 8,000 and 13,000 feet, and it makes its home in rock piles and slides. The reason why this creature suffers so much due to climate change is that of how they originally adapted to their…

Topic: Not Too Late for Polar Bears Specific purpose: To inform the class about the Arctic is warming too. How will Polar Bears survive by 2050?

He said they…

time period of when the polar bear and brown bear separated. Making a dependable time frame for when the polar bear emerged as a new species and how fast new adaptations to intense environments can occur in a large mammal. The population genomic formation evaluates the nuclear genomes of polar bear and brown bear populations. By doing so the researchers estimated when polar bears and brown bears diverged. They gather demographic history of the polar bear and brown bear to make it clear on what…
