By that logic all technology is "natural" and there is no distinction between the inventions of man and the creations of nature/god. Such logic sidelines self reflection, leading to horrible places.
No, it just means that self reflection must be based on something other than an arbitrary and meaningless distinction between things that existed before humanity and things that existed after humanity.
If we see ourselves as part of nature, but with a unique ability to impact more of nature than most other forces within nature, I think we would have a greater imperative to rectify mistakes we have made, vs seeing issues like climate change as mostly impact “others.”
All evidence and theories point to climate change being caused by humans. This interpretation does nothing to change that conclusion. My view is that it is an entirely useless distinction to make. If climate change were instead caused by natural sources of carbon dioxide, it would be no less a crisis, and would require no less of an intervention.
Only if you derive your morals in a nature good/synthetic bad frame, which is terribly naive. Nature is filled with awful things and awful acts.
Self-reflexion is the ultimate unnatural act which is (almost if not) completely unique to our species, and it's not to hard to argue not entirely ubiquitous within us.
