At first many country claimed their political control in Antarctica. In 1959 an Antarctica treaty system was established. According to this treaty, Antarctica is politically neutral, and no country can claim its government here. No military activity can be done here. No mining can be done here. Antarctica is considered below to 60 S. The countries which claim their territory in Antarctica are United Kingdom, Russia, Argentina, Chile, Australia, New Zealand, Norway, France, and USA.

Flora (Plants)




Mostly invertebrate animals and two species of vertebrates are present. A number of ocean animal are present which are dependent on algae species. These animals include penguins, whales, seals, orcas and squids. Fishing was prohibited here in an at established in 1980. But still illegal fishing is practiced.

Population





Antarctica has no permanent population. However some research centers work here all year. The population in these research stations, the population of scientists remain whole the year. In summer 5000 residents and in winter 1000 people live here in research stations. Russia has also made a catholic church at his centre. Permanent resident are only at South Georgia, governed by Britain.

Climate



It is most cold part of world. The lowest temperature at earth was measured -89 at Russian Vostok Research Station in 1983. Mostly in year temperature lies between -80 and -90 C. But in summer it is 5 to 15 at coastal line. But even that of normal temperature, no body can live there. Because ice reflects all ultraviolet rays, received from sun, which is harmful for human skin.
