"Death of the Last Tree" by Olivia O'Callaghan 
  

At some time in the future, the Last Tree is dying. It wonders why humanity culled the rest of its kind and what is so special about it so as to be spared. The humans deified this Last Tree due to its singularity and constructed buildings in its image. These duplicated images of the Tree are so numerous - as are the years that have passed since the penultimate tree died - that the Tree no longer can recall who or what it is. This drawing depicts the Tree's final moments as it looks across to a building which mirrors its own organic form and fractal structures, but the Tree can not recognise itself within its own duplicated image any more.
Its image lives on within the collective unconscious of humanity and buildings continue to be erected in the Tree's image even when humans have forgotten what a tree was.
