Polar bears and their retreating habitat essay

Many common infestations are due partially to humans and partially with bringing them over accidentally.

Increased Arctic shipping represents a risk to polar bears. Characterized by its low precipitation, minimum sunlight, and a layer of permafrost- a thick layer of ice that never thaws away- this biome is very cold, with temperatures as low as negative 70oC.

Geological Survey projects that two-thirds of Polar Bears will disappear by More common storms, droughts, heat waves, melting glaciers and warmer oceans, can directly harm the animals, and destroy their habitat.

As that specific scientific name Ursus maritimus shows, polar bears are actually marine mammals, which take much longer time at sea than on land.

Unfortunately, these interactions sometimes end badly for humans and bears.

The planet is truly in peril. Global warming has caused the polar bear population to decrease due to the results of having to swim longer distances, loss of habitat, and lack of mates to reproduce offspring.

Reducing conflict WWF supports community projects in Alaska and Russia to prevent unintended and potentially fatal encounters between polar bears and people. They are also found in Greenland, on islands off the shore of Norway, on the northern coast of the former Soviet Union, and on the northern and northwestern coasts of Alaska in the United States. We have also offered best practices for shipping in the Arctic and continue to work at the International Maritime Organization on a polar code that would make Arctic shipping safer. This expansion would likely affect polar bears and their habitat in many ways, including the following: Contact with spilled oil would be fatal. As you can see the Giant panda is classified as endangered. Male and female bears also meet on ice sheets to mate. WWF collaborates with scientists, conservationists and local people to oppose oil and gas development in areas whose ecological value is far too great for risking exposure to spills. Protecting the Last Ice Area of the Arctic Scientists believe that a natural safety net of ice in the High Arctic of Canada and Greenland covering million acres—or twice the size of Texas—may persist longer than the ice anywhere else. I spend most of my time hunting, breeding and climbing. They get around this by waiting near holes in the ice and ambushing the seals as they come up for air.

Antarctica consist about 90 percent of the world's ice and 70 percent of its fresh water Many adaptations make polar bears particularly suitable for living in ice habitats. An oil spill would affect the entire food chain. As you can see the Giant panda is classified as endangered.
