My Green House

In my green house,
I'm the greenest of green
My phone books are blank
So I can save ink
That would drip from the pages
And into the sink
That would flow to the sea
And kill manatees
Which would sadden sea things
And make them all cry
And in turn would make
Our sea level rise...
So I guess without contacts
I'm saving us all,
But how could I tell you
Without making a call?

Well in my green house
We never do speak
Noise pollution is dirty
And greeness we seek
So I'll shut myself up
And give you this post
So I can fulfill my role
As the greenest of ghosts.
