Mercy Mercy Me

Is there a more melancholy yet beautiful ode to the environment than this Marvin Gaye song?

Woo ah, mercy mercy me
Ah things ain't what they used to be, no no
Where did all the blue skies go?
Poison is the wind that blows from the north and south and east
Woo mercy, mercy me, mercy father
Ah things ain't what they used to be, no no
Oil wasted on the ocean and upon our seas, fish full of mercury
Ah oh mercy, mercy me
Ah things ain't what they used to be, no no
Radiation under ground and in the sky
Animals and birds who live nearby are dying
Oh mercy, mercy me
Ah things ain't what they used to be
What about this overcrowded land
How much more abuse from man can she stand?
Oh, na na...
My sweet Lord... No
My Lord... My sweet Lord

And here's a really interesting new take on it by the chamelion-like musician Susan Werner, from her new album "Classics".
