Sounds to me about something to do with the earth, and how we've destroyed it, sarcastically noting 'i love what you've done with the place' referring to our parents, whose decisions and their parents affected the state of the planet. However, also saying it's not too late to repair the damage, unless a juggernaught comes along (possibly referring to another asteroid impact, that would wipe out most species again (because one did it once before if you believe that an asteroid impact killed the dinosaurs).
