7.1.1 Wildness
Many people search out heritage landmarks for aesthetic experience. Both beauty and sublimity may be found in these places, they say. Therefore, we should preserve them because they are sites of the beautiful and the sublime. In particular, "wild" places, it is argued, are like art galleries where beauty and spirituality can come together in cosmic meditation.
William Wordsworth wrote that experiencing the beauty of what his vision of wilderness was produces "a motion and a spirit, that impels . . . and rolls through all things."
With regard to wildness, some argue that designated wilderness areas are places where the very meaning of aesthetic quality can be ascertained and that, therefore, all beauty is dependent upon such sites. Muir, for example, claims  that"None of Nature's landscapes are ugly so long as they are wild." 
The destruction of a designated nature conservation site would be as bad as, even worse than, the destruction of a painting by da Vinci or a sculpture by Michelangelo.   In principle, works of art can be recreated, but habitats with a primeval continuity cannot be replaced.
The intensity and type of beauty found in unique land forms, waterfalls, mountains, oceans, deserts, plants, and animals–all shaped by natural forces–cannot be replicated in urban or even pastoral settings.    These places are both necessary and sufficient conditions for a true sense of beauty. Hence, if the loss of this beauty is to be avoided the preservation of sites illustrating green and built heritage is mandated.
