Scientists believe they have discovered where in the world the cleanest air is, which is not polluted by human activities. That place is located in the Southern Ocean that surrounds Antarctica. "The Southern Ocean seems to be one of the few places on Earth that is less affected by human activity," said Thomas Hill, a scientist and co-author of the study.
