Instrumental value systems of nature have caused a divide between humans and all other living things. Even though weak anthropocentrism warrants a rational for use of nature for resources; it still only sees nature for what humans can take out. A separation is created because people do not see nature as having value if they cannot use it for something that they desire. This is contrasted by the intrinsic value of nature, which sees ecosystems as being valuable for what they are rather than what they possess. However, there is still a humanly assessed subjective intrinsic value which is different for every person. The objective intrinsic value is the only view that is independent of humans and evolutionarily independent. This makes defending intrinsic values difficult because it can also be subjective and not easily palpable. I believe that intrinsic value of nature is critical if the goal is preservation but unnecessary if conservation is desired. Intrinsic value is very firm in recognizing nature as more than resources so there should be not extraction rather than wise use in conservation.
I do not think that technological advances directly force a detachment between humans and nature but that is most likely what will happen. Technology can be used to make lives more environmentally friendly, but it may cause people to live in a bubble where they do not enjoy the outdoors. I believe that humans are connected to the planet in a certain intangible way and that long term separation will cause undesired effects on the human body and psyche.
