The Antarctic continent is located in the South Pole of our Planet. Its geography climate and biological conditions provide a unique enviroment.
Antarctica has the lowest temperatures in our planet reaching 70° Celsius below zero with winds of 300 km. Per hour. Containing 90% of the planets ice its the major reserve of fresh water on Earth.
About 99% of Antarctica is covered with ice at an average thicknes of 2500 meters reaching in some places as deep as 4776 meters. If the ice layer would melt all the Earths Oceans would rise 70 meters above the actual level.
The Antarctic Continent functions as one of Earths refrigerators regulating the oceanic currents and the worlds climate. Any significant enviromental impact would alter the global patterns of weather with disastrous consecuences.
In spite of the severe weather Antarctica has rich animal life amazingly well adapted to the harsh conditions.
The arrival of the first tourists in the 50s was a main cause of enviromental concern. Strict rules and regulations were created as to protect the ecology of the enviroment from the visitors such as creating restricted zones mantain a safe distance from the wild life do not feed nor touch the animals and rigid control of waste disposal.
During the summer months (being the pick of the season in January) there is daylight almost 24 hours a day while in winter the days remain on a prolonging half light or penumbra during most of the 24 hours.
