A Voyage to a ‘Snow White’ World

Talk about a trip to the end of the world, and you think of the Polar Regions. These are ice-capped regions that surround the Earth’s two geographic poles

As everybody knows, the Earth has two geographic poles
- the North Pole and the South Pole. To make an easy comparison, the Arctic is essentially a great ice-covered ocean surrounded by land, and the Antarctic is a gigantic, ice-covered continent surrounded by ocean.
In winter, these seas freeze into a solid pack ice.
These regions are the coldest parts of the world, and the ice, snow and freezing winds make them the most inhospitable, too. Yet, even in these frozen environments, life flourishes.

With the threat of global warming, the polar icecaps are shrinking, which may affect the world’s climatic cond itions and the lives of all living things on Earth? This issue of Tell Me Why takes you on a fascinating voyage to the wonderful ‘ends’ of the Earth.
