I Would Change Nothing

I would change nothing,

For the world is not a bad place.

I would change nothing,

What's wrong with the human race?

I would change nothing,

The grass was once green.

I would change nothing,

Now it is dried and lean. 

I would change nothing,

The sky was once pure and blue.

I would change nothing,

Now its black with shoot- and there's smog too.

I would change nothing,

The waters were once clean and clear.

I would change nothing,

Now there is toxic waste everywhere.

Now I might change something,

and I'm thinking of this,

Why not change the human's selfishness?
