It is a month away but it does take a while to brainstorm, plan and then organise events and activities.
Some things that might be interesting to try:
An event where people bring a poem or song or art piece etc that fits the theme and share it with the group
A discussion on existential risks
A wacky workshop where you think of alternate histories. Pick an event from the past where things could have gone differently due to the choices of people involved and think through what the world would like like now in that alternate timeline
