Most of the earth’s water supply is from the Arctic (Wheeler, 14).
Few people reside in the northern part of the Arctic Circle, and this is due to the climate which is not suitable for human living. The climate there is known as Arctic climate. The Arctic is defined by cold winters and cool summers. Years ago, the Arctic was covered by a vast area covered by snow. Within the years that have come to pass, the Arctic has become affected by the global warming that is currently present. Global warming has led to the decrease of sea ice, which covered the vast oceans. It has led to ice shrinkage and the release of methane gas. The Arctic also includes natural resources like oil, gas, minerals, fresh water and forest (Wheeler, 46).
Long ago, population in the arctic was characterized by a large number of animals, both water and land animals, and also a huge number of human species. Currently, the population of these is decreasing. The average temperature in winter is as low as -40 degrees Celsius. Before the current time, temperature recordings were as low as -68 degrees Celsius. Going by the current rate, the Arctic Circle is dropping from what it is supposed to be; cold, to a warmer climate. This is an effect of the global warming. The ice is melting thus the degree of coldness is decreasing. Animals residing in the Arctic Circle include the Arctic hare, Lemming, muskox, caribou. These are herbivores that are preyed on by the fox and the wolf. The common land animal is the polar bear, which prefers to hunt for marine food.
Marine mammals include seals, walrus, cetacean-baleen whales, narwhals, killer whales and belugas. Due to the changing climates, there has been a decrease particularly in the marine animals and land animals. Years before the Arctic were filled with marine life since at the time there was no climate change or the melting of ice. There was also decreased human activity like hunting which would
