Is the end of the world nigh, or just the end of the world as we know it? Are we set to doom-scroll our way to apocalypse? Or is this the moment we wake up to ourselves, change course, and save the planet? You decide the winner. Your life could depend on it.

Don’t miss this hilarious battle of brains and bravado when two teams join Big Ideas’ host and science journalist Natasha Mitchell at Hobart City Hall for the annual Beaker Street Festival Great Debate.

 

This episode of ABC Radio National’s Big Ideas was recorded live at Beaker Street Festival in Tasmania.
