 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 1 is very young.


-20,000 years ago, this exact spot where I'm standing 2, 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. But surprise I can go back those 20,000 years in an instant.
What would it look like?
-Well, for start, it wasn't even under water. This area would have been covered in hundreds and hundreds of miles. Have you collected some paperbark in forest, and it wouldn't have been a fish in science.
It was a land bounding 3 with the animals of Australian plains.
