In the article a point is made that not all "disturbance" is of human origin, referencing natural storms and floods as examples.
To consider another perspective, if one's preferred aesthetic is grassland plains, than the natural emergence of trees might be considered a disturbance.
In common lexicon, the term disturbed is also used in reference to a 'disturbed person', as in a mentally disturbed person -- generally also a negative or undesirable status, so in that context I would agree these negative or positive predispositions tend to be psychological phenomenon driven by conscious or unconscious perspectives.
