Bob Brown has spent the past 50 years trying to make people put the planet before profit. The environmental crusader, former senator and medical doctor, and founding member of the Wilderness Society has fought pivotal battles, including campaigns to save the Franklin River and the Swift parrot. He also practises what he preaches: he has lived sustainably for decades in a one-bedroom home.Today, to celebrate the 300th episode of Good Weekend Talks, deputy editor Konrad Marshall interviews Brown live on stage at the Melbourne Writers Festival.This episode comes to you from the State Library of Victoria, where we are joined by a live audience for a conversation that will cover everything from the origin of the term "tree-hugger" to how Brown still finds optimism in the face of massive challenges facing the world.
