  • Polar Bear Extinction

    Are polar bears facing extinction because of global warming? [pic] By: Aieron Levy Could global warming be killing polar bears? The weather temperature is rising because of global warming, this is due to changes in the entire Arctic eco system. Scientists suggest that warmer temperatures mean less lack of ice that polar bears depend on for hunting. As their normal habitat gets hotter it goes down in size, this consequence leads to fewer polar bears. For the polar bear, which...

    animal species that are in danger of extinction. Some are in danger because of the habitat destruction and hunting. People need to start protecting these animals or else many of these endangered animals will become extinct. The polar bear is threatened with extinction because of habitat destruction, hunting, and pollution; however, conservation groups and protection laws are working to save them.

    Polar bears are the largest land carnivores in the world, rivaled only by the Kodiak brown bears of southwestern Alaska. Polar bears sit at the top of the food chain in the biologically rich Arctic. The most carnivorous of the bear species, polar bears feed primarily on the fat of ice-dependent seals. The remains of these seals provide food for many other Arctic wildlife species, giving polar bears a vital role in their ecosystem. Polar bears are marine mammals, and spend much of their time...

    Global Warming has had a great impact on the polar bears To have a better understanding of how it is having an impact on them we need to understand the polar bear’s ecological niche. Polar bears are known to be the biggest carnivore on land. Polar bears have lots of fur on their body and on their feet, that act as snowshoes. Their creamy-white fur is dense and water-repellent, enabling them to shake dry after swimming. Polar bears have many adaptations that help them survive. They have...

Although it is closely related to the Brown Bear, it has evolved to occupy a narrower ecological forte, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet.

    Polar bears are large, white-furred bears which can weigh a maximum of 650 kg. They are the largest bears in the world. Interestingly enough, however, although their fur is white, their skin underneath is actually black. This allows them to absorb the sunlight in order to warm their bodies. This is a very useful feature, as they live in the cold climates of the Arctic. Polar bears are also capable of standing upright on their hind legs.

    The Polar Bear's fur is extremely thick and it traps the heat so well, you can't see one in inferred vision. This is good because the retention of heat keeps it permanently warm. It does not lose body heat as other animals and people do, and it would not be recognised by an inferred scanner, such as used when searching earthquakes and other devastated sites for survivors.
