Global Warming
There is no denying the fact that the concept of global warming envisages the warming of the atmospheric layer where the volume of carbon dioxide gas is tremendously increased. The state of growing up of Carbon-dioxide exists due to a shortage of plants and trees and green house effects. This global warming is a threat to the survival of polar bears in Arctic regions. Polar bears are ferocious and killer animals, but they have a vital role in keeping the environment free from pollution. And as such, our environment remains healthy and well-maintained due to the survival of such mischievous animals in Arctic regions.
We are aware that the ultraviolet rays emitted from the sun,
due to a tremendous increase in the atmospheric layer, the ozone layer is depleted, and
ultraviolet rays pass through the ozone layer and fall onto 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, modern scientists believe
that one day, the Earth will remain inundated underwater. Due to global
warming taking place in the Arctic region, ice melts, and as such, polar
bears find it difficult 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 are not able to save
sufficient food reserves in the form of fat inside their bodies. Thus, due to the colossal effects of global warming, polar bears are dying out day by day.
Polar bears
are of great use to us as they destroy poisonous insects and other dust particles, which are washed away by the tremendous flow of currents in the sea. A Polar
bear is a gigantic animal that damages all sorts of debris ahead of them while
moving. 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 the 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 the polar bear is very high, so 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 hunt them by hunting, but
it is tamed by long-term technical training and thorough observation of the
nature of the animals.
Canada is home to circa 16 000 of the estimated 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 recent 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 balance between living and non-living things, polar
bears play a vital role in keeping our environment healthy and pollution-free.
