In this short extract from the poem, the loss of the radiant maiden Lenore may be taken to symbolize, for modern times, the loss of nature herself, "nevermore" to be restored.  
In Australia, for instance, more than 1,700 species and ecological communities are known to be threatened and at risk of extinction. 

Read in an old man's voice to stimulate the ASMR effect (Autonomous Sensory Meridian Response) for those who can detect it, that is, the feeling of frisson or shivering that  moves down the back of the neck and upper spine.   

Once upon a midnight dreary, while I pondered, weak and weary,
Over many a quaint and curious volume of forgotten lore—
    While I nodded, nearly napping, suddenly there came a tapping,
As of some one gently rapping, rapping at my chamber door.
“’Tis some visitor,” I muttered, “tapping at my chamber door—
            Only this and nothing more.”

    Ah, distinctly I remember it was in the bleak December;
And each separate dying ember wrought its ghost upon the floor.
    Eagerly I wished the morrow;—vainly I had sought to borrow
    From my books surcease of sorrow—sorrow for the lost Lenore—
For the rare and radiant maiden whom the angels name Lenore—
            Nameless here for evermore.

    And the silken, sad, uncertain rustling of each purple curtain
Thrilled me—filled me with fantastic terrors never felt before;
    So that now, to still the beating of my heart, I stood repeating
    “’Tis some visitor entreating entrance at my chamber door—
Some late visitor entreating entrance at my chamber door;—
            This it is and nothing more.”
