Robyn and Jamie are joined by young naturalist and writer Dara McAnulty.
They chat about black holes, nature, the environment and inevitable comparisons to Greta Thunberg.
The 16 year old tells how difficult school has been and why writing every day helps him process it all.
Watch out for a tense moment where the conversation has to be put back on track, and a poem from Dara.
With Robyn Steward, Henry the bat, Jamie Knight and Lion.
Produced by Emma Tracey
