The Big Questions - S01E11 - is the future of migration already here?
play

03/17/25 • 33 min

Humans have always migrated, sometimes by choice and sometimes by necessity.

As the climate warms, our choices and reaction times will dwindle. Are we facing the movement of millions yearly, worldwide, or is this a regional issue? How should the global community adapt and prepare?

And intriguingly, how many Australians might find themselves in France in the coming decades?

Join our discussion on these pressing questions and how you, and decision-makers, can get ready for the future!

In today's episode, David Carlin and Simon Messenger are diving deep into the circular economy, a critical shift from our current "make, take, and waste" linear model which is pushing our planet to its limits.

The classic "Reduce, Reuse, Recycle" mantra is more vital than ever, especially when considering that if everyone lived like the average American, we'd need five Earths to sustain our consumption.

That's why widespread participation is key; it's not enough to redesign, remanufacture or revalue a few products or for a few to be environmentally conscious – everyone needs to do their part; everything needs to be reimagined.

To guide us through this essential topic, we're thrilled towelcome Vojtech Vosecky, a.k.a. the Circular Economist and a leading voice in the field, offering invaluable insights into rethinking a sustainable, and circular, future.

The Big Questions - S01E04 - Is the world big enough?!
play

02/27/25 • 37 min

How many hamsters can survive in a cage? And, similarly, how many humans can survive on earth?

Is the solution population control, or transforming our relationship with resources? With the richest 1% having a carbon footprint 1000x larger than the poorest, what happens if everyone adopts luxury lifestyles?

Join Simon and David discuss the cultural shifts, ethical considerations, and economic changes needed for a sustainable - yet prosperous - future. Not a return to the Stone Age, but a smarter path forward.

Why do humans often prioritize individual gains over collective well-being?

Is there a fundamental aspect of human psychology driving this behaviour, and what do economic models reveal about it?

The Big Questions - S01E02 - Will geoengineering save us?
play

02/21/25 • 40 min

Could fighting climate change really be as simple as writing a $10 billion check? What if sprinkling iron dust into our oceans could slash human emissions by up to 20%? Sounds too good to be true, right?

Welcome to the fascinating and controversial world of geoengineering - where bold solutions meet serious concerns. Is it humanity's ace up the sleeve against climate change, or are we opening Pandora's box? As the climate crisis intensifies, should we embrace these ambitious technological fixes, or are we risking even bigger problems?

Join David and Simon as they navigate the complex landscape of geoengineering, separating science fact from science fiction.
