The politics of school drop off and pick up has long been discussed, but a new study looks at one particular element — the environmental impact of so-called 'idling'. In this edition of the Conversation Hour we learn about the 'Idle off' campaign which saw students urge parents to turn off the ignition when they parked close to school in an effort to reduce pollution and give young people agency in the face of climate change.

Also in this edition, we pay tribute to singer songwriter Col Joyce and look at how streaming has changed song structures.
