The little farwell song

I stood still and was a tree amid the wood
Knowing the truth of things unseen before
The black rain stained my greenish lung
The toxic waste I sucked in,
All my arms were getting numb.

I lay down and was a stream, I crossed the land
Knowing the truth of things unseen before
A darkened carpet covered my skin
I’ve never seen the light again
Blind till then day I flowed away.

This is a song , a little one
To tell the world goodbye
And while we sing our song
We let our mother die.
