Imagine all this activity, this constant even flow of life continuing for over 2,000 kilometers. It's hard to believe that such a hugh solid structure hasn't always been here. But compared with the rest of Australia, this reef is very young. -20,000 years ago, this exact spot where I'm standing, it indeed the entire length of the Great Barrier Reef would have been high and dry. Back then in the middle of the last Ice Age, sea level was 120 meters lower than it is today, and the coastline was about 30 kilometers in that direction.
