This episode is about seven themes all related in some way to climate and creativity that keep coming to mind when I'm doing the watering, which is rather a lot at the moment:

• What can we learn from the Apollo missions?
• Harnessing the subconscious as a creative tool
• The wisdom of the allotment
• The end of sustainability
• Asking difficult questions
• Not seeking permission to sound the alarm
• Digital models of deckchairs on the Titanic
