The relationship between polar bears, antarctic ice sheet, sea level Essay

The relationship between polar bears, antarctic ice sheet, sea level rise and humans - Essay Example The research found variation in the extent of loss of ice in various regions of the continent of Antarctica. It was found that nearly all of the loss of ice happened in the Western Antarctic Ice Sheet. In another research, the volume of ice in Antarctica and Greenland was examined from 1992 to 2002 with the help of satellite radar altimetry. This study verified the findings of the previous study discussed above. Many species of animals are totally dependent upon the pack ice conditions. For polar bears, pack ice of the sea is the source of food and the place to live in. If the existing rate of melting of ice sustains for few more years, loss of ice in the sea will be sufficient to cause an altogether extinction of the polar bears. There has been some consideration about relocating them to Antarctica, but this would have its own repercussions. The drastic shifting might endanger the life of other Antarctic species along with that of the polar bears. Life of polar bears is endangered b y the rapidly melting ice in the sea which is fundamentally happening because of an overall rise in the temperature of Earth caused by the global warming.
