The physical environment is in some extent forming the culture, which is vice versa in some extent, reforming the physical environment. It is an interactive relationship and that is why the question of what is natural and what is artificial today is so complicated. It gets even more complex when we realize that absolutely untouched nature has actually become a fiction, as indirect human traces can be found everywhere. Humans are part of nature and creators of culture, so we stand somewhere in between, moving a bit from this side to the other, depending on our personal attitude or point of view.
