We Do Not Return to Nature. We Are Already There. This is my newest post up at No Unsacred Place; it was actually prematurely published on Friday, but it's already garnered some really good discussion and commentary, so please feel free to go take a look and what I wrote, and what others have said in response.
It's really solidified a number of things that I've been chewing over in my head for a while now, about the nature of "nature", and what that looks like for an increasingly urban species like humanity. It's probably the most coherent version of it that I've been able to write so far, though it obviously still needs some fine-tuning.
