When I met up with mammalogist, environmentalist, explorer and conservationist Tim Flannery in 2019, the world was a different place. Thanks to the work of activists like Greta Thunberg, humans were finally acknowledging climate change as a threat and policy makers taking note. There was more action, and more hope.

Then 2020 happened and everything changed. The plight of the Great Barrier Reef and rising greenhouse gases pale almost to insignificance when you’re watching family, friends and neighbours suffer, but the negative effects of our presence on this planet continue relentlessly. Tim CARES so very much, and hearing him offer solutions to the greatest existential threat of our time may give you back some hope. As he says in the episode, ‘This isn’t a game. This isn’t about tribalism. It isn’t about identity. It isn’t about politics. You are threatening my children. So justify that, or get out of the way’.
