The answer is that it's not binary, despite everyone's insistence on framing it as such. We are a part of nature, but we do have some degree of power and responsibility over it that other species don't. It's not absolute, it's murky and messy, defined by the relative magnitude of power and our estimates of it. I think this framing addresses both our relationship within our ecosystems, above our ecosystems, and in the distant future, beneath some larger cosmic ecosystem that may exist that we don't know about yet.
