How would you relate the title of the poem to what is happening now on the earth

I think you are referring to Autumn.

Every Autumn, the trees starts to turn color orange, a sign that the leaves will soon fall out of it's branch and the season of Fall will begin. After this season, Winter comes and Spring will sprung and leaves will grow again, making a greenish scenery wherever you look.

Like so, our nature is beggining to fall out, fading its beauty. But we can resore it.

Change is constant, as changing from a filthy place into a friendly surrounding is possible. We can make it look majestic again how once it'd been.
