Why is Antarctica the place to go to understand the earth’s past, present and future?

Antarctica is the only place on earth that has not supported human population. Therefore, it remains almost as pure, as it used to be millions of years ago. There we can observe how a little change can affect the environment. Besides, half–a–million–year–old carbon records lie trapped in its layers of ice. Therefore, if we want to study the Earth’s past, present and future, Antarctica is the right place.
