Antarctica is located in the South Pole and has a unique environment due to its geography, climate, and biological conditions. It has the lowest temperatures on Earth, reaching as low as -70 degrees Celsius with wind speeds up to 300 km/hr. Antarctica contains 90% of the world's ice and is the major fresh water reserve. Nearly all of Antarctica is covered by ice that averages 2,500 meters thick and reaches as deep as 4,776 meters in some places. If all the ice melted, it would cause the oceans to rise 70 meters. Antarctica regulates ocean currents and the global climate, so any environmental impacts would significantly alter weather worldwide. Despite harsh conditions, Antarctica has diverse animal life well-adapted to
