September is biodiversity month, highlighting that we have more than 1,000 threatened species in NSW alone. Now is the perfect opportunity to learn about how we depend on biodiversity in everyday life, often in ways that are not always apparent or appreciated.

In this episode, you'll hear from an ecologist and an astrophysicist who shed some light on some of the unexpected ways we rely on threatened species.
