1Antаrcticа represents оne оf the lаst resоurce frontiers left on the planet Earth. 2It is 98 percent covered by ice, and its low annual precipitation of less than 8 centimeters makes it a virtual desert. 3Its snow and ice hold 90 percent of the world’s fresh water. 4The ice-covered land is inhospitable to life, but the edge of the ice and the surrounding offshore areas have a rich fauna—whales, penguins, seals, seabirds, fish, and an economically important shrimplike species known as krill. 5In the early 1900s, several nations claimed territory in Antarctica. 6Scientific interest in the region grew, and research activities evolved into cooperative research agreements among twelve nations (the United States, the Soviet Union, the United Kingdom, Belgium, Japan, South Africa, New Zealand, France, Australia, Norway, Chile, and Argentina), who were joined by four others (Poland, the Federal Republic of Germany, Brazil, and India) in signing the Antarctic Treaty that took effect in 1961. 7Sixteen more nations subsequently joined in the treaty. 8The treaty established Antarctica as a demilitarized, nonnuclear area and guarantees freedom of scientific investigation. 9The treaty also provides for free exchange of information among all researchers, and the participating nations agree not to assert any territorial claims while the treaty is in effect.
