The concept of global warming

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 image of Canada’s wildlife tradition, is of great cultural significance to the Canadian people. For the Inuit and many northern societies, polar bears are especially noteworthy culturally, spiritually and economically. Canada has a sole preservation concern to safeguard these iconic creatures. This is one reason why Canada has puffed-up 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 ensue in that 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 germane.

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. Global warming is the upswing in the middling temperature of Earth’s atmosphere and oceans since the late 19th century and its projected continuance. Since the early 20th century, Earth’s average surface temperature has augmented by about 0.8 °C (1.4 °F), with about two-thirds of the rise occurring since 1980. Reheating of the changing system of the climate is unambiguous, and scientists are more than 90% certain that it is principally caused by growing absorptions of green gases formed by human activities such as the burning of fossil fuels anddeforestation. These findings are documented by the national science academies of all foremost industrialized nations.[
