Imagine a time when the earth was pure. And imagine a time, tens of thousands of years ago, when all of earth’s water was original, untouched, and absolutely perfect. Imagine water absorbed by the clean atmosphere, and then falling as snow. More snow falls and, it becomes compressed, becomes ice and, as thousands of years pass, it is locked deep and safe inside Greenland’s frozen heart. The heart beats, the ice moves, and gradually it breaks away and an iceberg is born.
