Antarctica is the only place in the world which has never sustained human population and therefore remains pristine in this respect; but because it holds half-million-year-old carbon records trapped in its layers of ice, it is a very important element in the debate of climate change. There are no trees, animals or buildings here. The world's geological history is entombed in Antarctica. One can see ice-sheets breaking, water level rising, seals taking sun bath on the ice floors. One can also walk on the thin layers of ice and could feel the life under our feet. He can see icebergs as big as a small country. So, if the scientists want to understand the earth's present, past and future, Antarctica is the place to go.
