Polar Bears Going Extinct

Some of the polar bear populations are in decline currently, although more than half of the sub-populations are not in decline. This is mainly due to global warming, which are reducing the ice sheets which are the polar bears main hunting grounds.

Hunting was the main factor in the reduction of polar bear numbers, until recently, although it is still a problem, and considered unsustainable by scientists. Polution was also a problem, but is decreasing in effect on polar bears, now, due to regulations banning some chemicals.

If global warming continues at its current rate, the polar bear might be extinct in about 100 years time, although scientists disagree on this, some saying that the populations are managed well enough to survive. Although polar bears did learn to adapt to warmer times in the past, their currently smaller population sizes, and the rapid rate of current global warming might makethem extinct before they can adapt this time.

Unfortunately, legal protection of polar bears is oppsed by oil and gas interests, and illegal poaching is common in some areas such as Russia.

Polar bears are classified as marine mammals, because they spend most of their time on the sea ice hunting for the seals which live on and under this sea ice. As this sea ice melts due to global warming, the polar bears are less able to find enough food.

Polar Bear Facts.

Polar bear facts are fascinating. The polar bear has a scientific name of “Ursus maritimus”, which means bear of the ocean. They live usually within the arctic circle and the arctic sea. Due to reducing amounts of ice in the arctic, which it needs to hunt, they are having challenging times currently and some populations are reducing. However compared to other carnivores, it is still found throughout a greater amount of its original habitat than any other.

The polar bear is the largst meat-eating animal found on land, and also equal largest bear with the kodiak bear. Females are typically about half the size of males.

The closest relative is the brown bear and if the two species mate they can produce live young. However neither species can live successfully in the other’s habitat.

There are probably less than 25,000 of them left alive today and they could become extinct within the next 90 years especially if the sea ice continues to reduce in their hunting areas. Their sense of smell is much better than a human’s . . . they can smell a seal (which is their main food) a mile away. However their hearing is no better than a persons.

A polar bear will get too hot if the temperature is more than ten degrees centigrade because of their thick layer of body fat which they need to survive in the arctic.

Most of the lifetime of a polar bear is spent on the sea-ice hunting seals. They can swim about twice as fast as their usual walking distance and will swim very long distances such as several hundred miles. While their main food is seals, they will also sometimes eat beluga whales or walrus (which are up to twice their size). They can go for several months without eating anything when they need to.

Scientific Name For Polar Bear

Scientific Name Polar Bear

The scientific name for a polar bear is “Ursus maritimus”. “Ursus” means “bear” and “maritime” means of the ocean.

This magnificant animal is found mostly within the arctic circle and the arctic sea, and is the largest land carnivore. It is classified as a vulnerable species and some of the populations are declining. The most significant difficulty for it is the melting of the sea ice it needs to hunt.

Here are a few great photos of polar bears . . .

Interesting facts on polar bears

Polar bears live mostly within the artic circle. It is the largest carnivore found on land, and equal largest bear with the kodiak bear (which is an omnivore). It is also the carnivore which has retained its survival throughout more of its original habitat than any other.

Male polar bears are about twice the size of females. The brown bear is a close relative, but the polar bear has evolved, about two hundred thousand years ago, to fit a much more precise habitat. Brown bears and polar bears can produce offspring together, but neither can live long in the others habitat.

The decrease in sea ice due to global warming is causing big problems for polar bears. They are considered “vulnerable” now and might become extinct within a century. Polar bears are still hunted by local peoples. There are probably not more than twenty five thousand polar bears alive today.

Many people think that polar bears are left-handed, but there is no scientific evidence of this. A polar bear will overheat in temperatures above 10 degrees C (50 F) due to their layer of blubber about ten centimeters thick.

The outer hairs of a polar bear appear white but are actually transparent.

A polar bear can smell a seal a mile away, but its hearing is only as good as humans. Polar bears can swim very well, and have been seen two hundred miles from land. They swim almost twice as fast as they walk.

Polar bears eat mainly seals, which they hunt from sea ice, where they live most of their lives. Polar bears hunt seals either by waiting for them to come up to breathing holes, or by stalking them when they are resting on land. Mature bears will mostly eat only the skin and blubber of the seal which is rich in calories, but young bears eat mainly the meat which is rich in protein. They wash themselves after eating, in either water or snow.

Polar bears occasionally eat walrus (which can be up to twice its weight) or beluga whales. A polar bear can survive without eating for several months.
