Global warming, which is a phenomenon of the recent times occurring within the 20th century, results from rising of the average temperatures of the atmosphere and oceans of the world. The rise in temperature leads to warming of climatic systems, of the world, especially the Arctic and Antarctic regions (Polar Regions) leading to devastating effects on both terrestrial wildlife and aquatic life. The level of certainty, by scientists, “that global warming result from the increase in concentration of green house gases in the atmosphere, due to human activities, such as burning of fossil fuels, deforestation, and the continued use of harmful insecticides, is 90%” (Lubin, 2008) Further projections, by intergovernmental panel on climate change, indicate that, in the 21st century, global surface temperature is probably rising by 1.1oc to 2.9oc due to further accumulation of green gases from the continued human activity. High surface temperatures lead to “the melting of ice in Polar Regions such as the Arctic and Antarctic regions causing a rise in the ocean and sea levels, which affects the amount and pattern of precipitation and expansion of subtropical deserts” (O’Neel, 2008). Further prospects indicate that, global warming would result into extreme climatic changes with heat waves, droughts, species extinction, changes in crop yields and heavy rainfall. The expected strong warming on the Arctic regions of the world will lead to ice melting causing significant rise in the sea and ocean level even beyond the polar region. The rise in sea levels, resulting from the melting of ice in the Arctic region, destroys aquatic habitats, as well as the terrestrial habitats, when the rise displaces terrestrial wildlife along the coastal lines (O’Neel, 2008). On the other hand, the adverse climatic changes due to global warming leading to droughts and expansion of deserts, affects the wildlife, both plants and animals, as food shortage and destruction of habitats sets and thus Arctic ice melting will have major effects beyond the polar region. The growth and establishment of sustainable wildlife depends largely on the availability of a healthy habitat with elements of good temperature, fresh water, good source of food, and good places to raise the young ones. Global warming affects negatively on these constituents of a good habitat in that, it causes an increase in temperature ranges, destruction of food sources, and deflowers fresh water bodies meant for wildlife consumption. Temperature rise in the Arctic region leads to increase in the level of ice melting thus destroying the hunting grounds for polar bears. The removal of hunting grounds puts polar bears on the risk of extinction due to lack of sustainable food supply. Moreover, warming of water bodies due to melting of ice eventually leads to reduction in population of animals surviving in cold environments such as the trout and salmon. Bleaching of massive coral ecosystems destroys breeding grounds for many species of fish due to global warming and increase in ocean temperatures. The destruction of coral reefs destroys the substratum for the growth of phytoplankton, which serves as food for different species of fish. The reduction in the food supply in the ecosystems adversely affects the population gr
