Stars were bright whence they came

Now dimmed, obscured, pollution's haze

So let us plant a better seed

Our waters, skies, wildlife and trees

Are all examples of internl rhyme.

Explanation:

All right, Internal rhyme is the concept given to the rhyme that can be found or built in the same line by different words. In other words is the employment of words ending with the same sounds, not letter because remember the rhyme is based on sound. That jump to repeat the same sound in a line instead of at the end of the next line. So:

Stars were bright whence they came.

Is an example of intern rhyme because of the sound of were end whence words.

Also:

Now dimmed, obscured, pollution's haze

Because of the sound of dimmed and obscured words' ends.
