Ah, mercy, mercy, mercy, mercy
Ah, mercy, mercy

Oh, mercy, mercy me
Oh, things ain't what they used to be
No, no
Where did all the blue sky go?
Poison is the wind that blows
From the north, and south, and east

Oh, mercy, mercy me
Oh, things ain't what they used to be
Oil wasted on the oceans and upon our seas
Fish full of mercury
[ Lyrics from: http://www.lyricsfreak.com/b/boyz+ii+men/mercy+mercy+me+the+ecology_20832157.html ]
Oh, mercy, mercy me
Oh, things ain't what they used to be
Radiation under ground and in the sky
Animals and birds who live nearby are dying

Oh, mercy, mercy me
Oh, things ain't what they used to be
What about this overcrowded land
How much more abuse from man can you stand?

Oh, Lord
Oh, Lord

Oh, mercy, mercy, mercy
Oh, things ain't what they used to be
Where did all the blue sky go?

Mercy, mercy, mercy, mercy
Mercy, mercy

Mercy, mercy, mercy, mercy
Mercy, mercy
