Redclift and Woodgate also mention that there is no dividing line that can be drawn to say what is natural and what its not. Everyone, based on how they grew up, may draw their own line depending on their standards, but nature and culture are so closely related that there can be no line set without having one or the other. Natural may be defined by nature, but culture today always somehow leaks into nature. To determine how natural something is, is to measure how much culture has crept into this natural nature. According to the way we have been raised our thoughts will always be affected by culture, so nature will always be interpreted differently.
Culture influences nature, just as nature influences culture.
This can be seen from the natural links of the advertisement, on how nature has spread onto culture. As William Cronan talks of nature and culture, he points out We can only take them together and, in making the journey between them, find a way of life that does justice to them both. As can be seen by the analysis of the ads discussed, definitions of natural will always be greatly influenced by our cultural and background experiences.
