I'm not sure I see why a the effects of human lives are any less "natural" than the effects of the lives of any other animal...And despite protestations by Japanese about how important "nature" is in Japanese society, the average Japanese person lives much further away from what we normally consider nature than the average American, IMO.
IMHO, we have lived so far from nature that we are more socialized normal. Feeling natural often means just feeling familiar and habituated.
While nature sounds good, I personally don't see many people actually making a decision to walk in that direction on a daily basis. Do you?
Thanks for reading and responding.
