Slide1:  Antarctica Satellite View Slide2:  The Antarctic continent is located at the South Pole of our Planet. Its geography, climate and biological conditions provide a unique enviroment. Slide6:  Antarctica has the lowest temperatures on our planet reaching 70° Celsius below zero with winds up to 300 km. per hour. Containing 90% of the planet’s ice, it is the major reserve of fresh water on Earth. Slide12:  About 99% of Antarctica is covered with ice, at an average thickness of 2,500 meters, reaching, in some places, as deep as 4,776 meters. If the ice layer melts all the Earth’s Oceans would rise 70 meters above the present level. Slide17:  The Antarctic Continent functions as one of Earth’s “refrigerators”, regulating the oceanic currents and the world’s climate. Any significant enviromental impact would alter the global patterns of weather with disastrous consequences. Slide22:  In spite of its severe weather, Antarctica has rich animal life amazingly well adapted to the harsh conditions. Slide27:  The arrival of the first tourists in the 1950’s was a main cause of enviromental concern. Strict rules and regulations were created to protect the ecology of the enviroment from visitors, such as creating restricted zones , mantaining safe distances from wild life, and not feeding or touching the animals; and rigid control of waste disposal. Slide33:  During the summer months, the peak season, in January, daylight lasts 24 hours a day, while in winter the days remain on a prolonged half light, or penumbra, during most of the 24 hours.
