Stephanie Davis from the Australian National University gives us the low down on the Corona virus.  Presented by Tom Street and Atul Sharma.

If there's a triumph of modern civilisation, it's the efficiency with which products such as food are delivered to our shelves.

That's an amazing thing, but it hides the hugely complicated system that makes it all happen. The largely invisible process can make us blind to our connection to the land.

Why do we waste so much food, and what can we do about it? What can we do to make agriculture more sustainable?

We tackle these questions with our guests Dr Bethany Turner and Dr Ro MacFarlane from the University of Canberra. Interview by Rod

With firestorms and floods ravaging Australia, now is the time for leadership on climate change. While that's missing on the national level, in Canberra we have just achieved 100% renewable energy for a 40% reduction in the city's greenhouse emissions.

It's a good start, but the job's not done yet.

Shane Rattenbury roles include being ACT Minister for Climate Change and Sustainability. He tells the story of how we got this far, and where we go next.

In this show scientist Lennart Bach from the Institute in Marine and Antarctic Studies in Tasmania talks about the possible side effects of negative emission technology, ocean acidification's effect on marine plankton communities and other thoughts on our climate future. 

On todays episode

Jamie Kirkpatrick, geographer and conservation ecologist from the University of Tasmania talks about bushfires.

Zanna Chase, professor of oceanography at the University of Tasmania, talks about some of her research into oceanic drivers of climate change.

There are only seven meals between civilisation and anarchy. But we're okay in Australia, right? There's always food in the supermarket and shortages are what happens in other places. Not here.

The horrendous current drought, record heat and devastating fires across our country are a hint that we should lose our complacency because Australia is vulnerable. In spite of what our Prime Minister seems to think, climate change is here and it's happening right now.

Julian Cribb's latest book is Food or War. It's a fascinating dive into the history of civilisations that went hungry. With foresight we can avoid it, but how? Spoiler alert: we must act soon.
