Lyric discussion by macky17 

I think the song references Buddhism. The Big Wheel is the clock which counts the seconds of each age of the Earth - each epoch separated from the next by an apocalypse or cataclysm of some kind. The reference to 'beneath a new tree' is also Buddhism - the tree is a metaphor for the an epoch of time, or for the world as it exists within that period. Unfortunately I think the song is a reference to the fact that according to this religion, as well as Mayan prophesies, etc. the current age of Man (the current 'tree') is about to come to an end and largely because of the damage to planet humans have caused ('On the surface of the wheel, they build another town, and so the green comes tumbling down'). Great song and very deep.
