The hint to the song's meaning is in there. It's about sustainability. This final track from the album is Rou wrapping up everything he's said throughout the album, and openly saying that he hopes for a sustainable future, though it may be too late for him, 'I'm lost so lost, but you're the constellations'. The constellations are the future generations who will do better than current generations. References to time in the song are based on the Doomsday Clock (see Wiki). 'We need to use our own two feet to walk these tracks' is referring to the fact that despite being promised sustainability, government haven't followed through and the only way to achieve it is to make it happen ourselves. Spend some time reading up on sustainability and the Doomsday clock and you'll appreciate this song like never before.
