I'm a big fan of JRR Tolkien's "Lord of the Rings". The Brobdingnagian Bards were working on a tribute album to Tolkien , called Memories of Middle Earth which has me writing songs. This one is a good environmentalist song about Treebeard and the Ents, and the troubles they must face to thrive in a world where people destroy without care.

Long before men tread Middle-Earth,
Before the dwarves and elves gave birth,
There sprouted a race for the trees' defense
In the heart of Fangorn, there live the Ents.

Ha-room... Ha-da-ra-room.
Ha-room... Ha-da-ra-room.

Patient farmers they tend the woods.
Gaurdians of stems and of roots.
They hear the arbors' laments and wails
From falling axes and tearful trails.

For Living Creatures all roam the land,
But hasty judgements make careless hands.
One thoughtless word from a thoughtless king
A thousand creatures die beneath the trees.

The rivers will flow though their course may change.
The birds are born and will fly away.
Men will come and men will go,
But the Ents remain through the melting snow.
