Big Yellow Taxi - Joni Mitchell

The woman starts by singing about paradise being paved over, with trees and flowers being lost to industry. But at the end of the song, you learn about the real loss.

Last last night, I heard the screen door slam
and a big yellow taxi took away my old man
Don't it always seem to go,
that you don't know what you've got till it's gone.
They paved paradise and put up a parking lot.
