We’re throwing away millions of kilos of clothing every week — and our hospitals are among the worst offenders. This week, Hugh and Dan speak with Tom Dawson, founder of Revolution Zero, to explore the hidden environmental disaster of textiles — from fast fashion to hospital scrubs.

Tom reveals how healthcare’s obsession with disposables is fuelling climate change and why polyester might just be the unlikely hero in our fight for a sustainable future. From washing your clothes colder to rewriting hospital laundry standards, Tom lays out a compelling case for reusables, circular systems, and local jobs.

If you've ever worn clothes (yes, that’s all of us), this episode is for you.

The climate crisis isn’t just about rising seas and hotter summers. It’s about national security, migration, infrastructure, and global stability.

In this gripping episode, Lt General Richard Nugee joins Professor Hugh Montgomery and Daniel Grant to talk about:

• Why climate change is a defence and security threat
• What militaries around the world are already doing to adapt
• How fossil fuel reliance weakens operational resilience
• What civilian governments could learn from military planning
• Why solving climate change is now a matter of survival, not sustainability

This episode goes far beyond the usual conversation — into geopolitics, defence, and disaster readiness.
