The state of growing up of Carbon-di-oxide exists because of shortage of plants and trees and green house effects. Polar bears are killer and ferocious creatures but they have an essential role to keep the environment free of pollutions. And as such our environment remains healthy and upkeep due to survival of such mischievous creatures on arctic regions.
We are conversant that the ultraviolet ray emit from sunlight and because of 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 planet’s surface layer is warmed up and ultimately, the height of the sea level goes up. In this regard, the modern scientists feel that one day, the earth will remain inundated under water. Because of the global warming happening to the arctic region, ice melts down and as such polar bears find difficulties to live on earth. In cases like this, some polar bears are found missing and somehow, some survive through constant suffering and painstaking efforts. The polar bears who somehow endure find less food during this time. When their hibernation begins, they cannot be able to save sufficient food reserves in the shape of fat inside their bodies. Thus, due to colossal effects of global warming, arctic animals are being died out day by day.
The arctic animals are of great use to us since it destroys toxic insects and other dust particles which are wasted away by tremendous flow of current from the sea level. A Polar bear is a gigantic animal which damages all sorts of debris ahead of them while locomotion. It develops another entity within the arctic region and survives for years together. No individual 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 therefore, hunting of polar bears is difficult. The smelling power of these dangerous species is extremely high for which it can easily learn the whereabouts of the prey. The hunter generally shoots from a long distant apart into the polar bear and suffice it to say, it’s 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 mischievous species in the international polar areas. It is no wonder that this icon of Canada’s wildlife heritage, is of great cultural significance to the Canadian people. For the Inuit and many northern communities, dangerous species are especially important culturally, spiritually and economically. Canada has a lone preservation centre to safeguard these iconic creatures. That is one reason why Canada has amplified investment in detecting efforts in current years. Canada’s portfolio program for the critters of the arctic covered countries is designed to make sure that there are up-to-date population estimates for all 13 subpopulations which occur in our country. While monitoring, it’s thought-provoking due to the distant and inhospitable environment of the Arctic areas, population estimates can help ensure that upkeep and management actions are applicable.
In light of the above, global warming is a great threat to the survival of the animals of the arctic regions like the wide ranging dangerous species across the world. Within the sphere 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.
