This year Earth Hour produced ‘Lights out for the Reef: an Earth Hour special’, a documentary filmed on location at the Great Barrier Reef. The documentary uses humour to carry a very important message: climate change is happening right now and affecting one of Australia’s most loved natural icons: our Great Barrier Reef.

In ‘Lights out for the Reef: an Earth Hour special’ two of Australia’s most famous YouTube sensations, Natalie Tran (community channel) and The Axis of Awesome, are sent on a mission by Dr Karl to travel to the Great Barrier Reef to find out how it can be saved from climate change, and how we can all help. Axis write a rock song about coral, while Nat falls in love with a baby turtle.
