While the present humanity is characterized by ever increasing technology, massive production, and emerging economies, it faces a serious threat of a complete, eventual annihilation from global warming. Global warming has reduced snow-covered area in the northern hemisphere. It has caused many of the icebergs to floating in the Arctic Ocean. Due to this increase in temperature, large portions of Antarctic ice have been separated from the rest of the polar body, thereby reducing the size of the frozen continent (David & Cambria, p. 24).
