Global warming is a bottleneck to the survival of polar bear

The concept of global warming envisages the warming of the atmospheric layer where the
volume of the Carbon dioxide gas is tremendously increased. The state of
growing up of Carbon-di-oxide exists due to shortage of plants and trees and
green house effects. This global warming is a threat to the survival of polar
bears of arctic regions. Polar bears are ferocious and killer animals but they
have a vital role to keep the environment free from pollutions. And as such our
environment remains healthy and upkeep due to survival of such mischievous
animals on artic regions..

We are conversant that the ultraviolet ray emit from the sun and due to tremendous
increase in atmospheric layer, ozone layer is licked and ultraviolet rays pass through he ozone layer and fall into
the surface of the earth.. As a result, the earth’s surface layer is warmed up
and ultimately, the height of the sea level goes up. In this respect, the
modern scientists believe that one day, the earth will remain inundated under
water. Due to the global warming taking place into the arctic region, ice melts
down and as such polar bears find difficulties to survive on earth. In this
case, some polar bears are found missing and somehow, some survive through
continuous suffering and painstaking efforts. The polar bears who somehow
survive find less food during this time. When their hibernation starts, they
cannot be able to save sufficient food reserves in the form of fat inside their
bodies. Thus, due to colossal effects of global warming, polar bears are being died
out day by day.

Polar bears are of great use to us as
it destroys poisonous insects and other dust particles which are wasted away by
tremendous flow of current in the sea level. A Polar bear is a gigantic animal
which damages all sorts of debris ahead of them while locomotion. It develops a
separate entity inside the arctic region and survives for years together. No
separate entity is to be developed around the globe outside arctic region. There
is no denying the fact that the Polar Bears are dreadful animals and as such hunting

of polar bears is difficult. The smelling power of polar bear is very high for
which it can easily learn the whereabouts of the prey. The hunter generally
shoots from a long distant apart to the polar bear and suffice it to say, it is
very cumbersome to reach them by haunting but it is tamed by long time technical
training and observation thoroughly the nature of the animals.

Canada is homespun to circa 16 000 of the appraised
20 000–25 000 polar bears in the global polar areas. It is no wonder that the
polar bear, an icon of Canada’s wildlife heritage, is of great cultural
significance to the Canadian people. For the Inuit and many northern
communities, polar bears are especially significant culturally, spiritually and
economically. Canada has a sole preservation concern to safeguard these iconic
creatures. This is one reason why Canada has amplified investment in observing
efforts in current years. Canada’s portfolio schedule for polar bears is
designed to ensure that there are up-to-date population estimates for all 13
subpopulations that occur in our country. While monitoring is thought-provoking
due to the distant and inhospitable environment of the Arctic, population
estimates can help ensure that management and upkeep actions are applicable.

In view of the above, global warming is a great threat to the survival of the polar bears,
a wide ranging dangerous species throughout
the world. In the field of ecological balances in between the living and the
non-living things, polar bears play a vital role to keep our environment
healthy and pollution free.
