Songs about ecology


I was going to make a collection of ecology songs and need some help. So far I have Mercy Mercy by Marvin Gaye and cover by Robert Palmer. Big Yello Taxi by Joni Mitchell and Natures way by Spirit. Any help appreciated.

John Prine's "Paradise." How could I have forgotten that great song?! It's all about coal mining companies ravaging the landscape. Here's one verse in particular:

Then the coal company came with the world's largest shovel
And they tortured the timber and stripped all the land
Well, they dug for their coal till the land was forsaken
Then they wrote it all down as the progress of man.

And the song's chorus:

And daddy won't you take me back to Muhlenberg County
Down by the Green River where Paradise lay
Well, I'm sorry my son, but you're too late in asking
Mister Peabody's coal train has hauled it away
