I interpret this song as the feelings of isolation the singer is feeling and his surrender to our slowly dying world. He looks down at pollution (landfill, dead grass), universal suffering (the whole valley looks like someone's body / and all the people look like little scars), and the lost of what was good and pure in the world (where Eden was before / But not anymore)...
He knows that the state of the world is too overwhelming for him to change, and for this he feels he can only observe things through "a thousand windows" and is unable to reach out and help because he is trapped, "without doors." So he accepts this unconditional fate.
