The Last Great Wilderness

Andrew Luck-Baker ventures into Australia's Daintree rainforest canopy with the help of a mechanical crane, which for the first time offers detailed access to the tree tops in the quest to unlock the forest's biological secrets.



The forest canopy remains one of the world's most inaccessible places.

Besides being the main interface between the atmosphere and life on Earth in the control of our climate, it's thought that 40% of all species live there.

The forest canopies are considered to be the great lungs of the earth, where the atmosphere meets the biosphere.

Andrew Luck-Baker meets climatologists to assess how trees will contribute to global climate change.
