Greens Leader Bob Brown on How to Save the World

Speaking with Bob Brown makes us all feel a little lazy. He is, Australia's Humanist! Doctor, Senator, environmentalist, activist, leader and writer are some of the roles he's occupied but his reach is much wider than that. It's lonely at the top and from having to go it alone on many issues in parliament, he's now seen as a figurehead to the next generation of climate activists and those who choose to care about the planet. Strap yourself in, it's time to save the world.
