Normally, 10 percent of land area on Earth is covered with glacial ice, including glaciers, icecaps, and the ice sheets of Greenland and Antarctica. Where is areas cover over 15 million square kilometers (5.8 million square miles).however, when glaciers melt become to fjords. That I feel for Earth there are many problem involve pollution. when it comes to defending their food supply from frankenfoods; I admire Europe for how much much more vigorously they defend their food (consider that the controversial milk hormone rbST is banned in the EU, and that strawberry sundae you buy at a local fast food chain in the US has Red Dye #40 in it, while in Europe it contains beet juice extract).
