Lyric discussion by natty_g 

sld potato: that's a cool way to interpret it. BUT, after looking into it some more i found another version of the song, with an extra verse at the end. it goes:

There's no more hugging in the kitchen, No more pats on the back in the hall. No more chest on breasty chest behind the curtain. No more lip on nape of neck in shower stall. No more cosy gardens or craving curvy hips on my belly. I'm giving up so I can be free from you. I'm paying fees so I can sever ties from you. Let craving call and beg and bawl, and face it tall. Let my soft skin have more sweet soft air on me. Let boulders drown.

so i think it's safe to say that this song is not about the earth, rather, in accordance with several of the other opinions, it is about letting go of a difficult relationship.
