To Observe Silence on Earth Day

I read today that every tree
Has its own, unique, song. And I imagine
Choirs in the forests, full-throated,
But only when the last human
Is gone. Because music, thus noted,
Thus aired, thus floated,
Cannot possibly be heard for free.

Maybe it’s too late to pay our dues
Maybe those tall singers dance
To another muse. Maybe their song
Is not something we can choose
To be. Because music thus spoken,
Thus worded, thus broken,
Cannot possibly be heard for a fee.
