Beyond this, it has been defined as a quality produced in nature, as that which emerges from a forest, and as a level of achievement in nature .

A wilderness is a place where wildness occurs . </P> <P> People have explored the contrast of wildness versus tameness throughout recorded history .

Ambiguities about the distinction between the natural and the artificial animate much of art, literature and philosophy . There is the perception that naturally produced items have a greater elegance over artificial things . Modern zoos seek to improve the health and vigour of animals by simulating natural settings, in a move away from stark man - made structures . </P>
