> Not sure why folks seem to want to exclude humans from nature
Probably because the concept of "nature" no longer serves any purpose if you don't, as it doesn't exclude anything.
It's often a pointless distinction to make (see also: anything that labels itself as "organic"), but it's a convenient shorthand to describe a category of interactions that people often want to talk about.
Perhaps, then, "nature" is a somewhat dated concept that is no longer especially useful to have in such broad circulation, given that it encourages folks to exclude humanity from analysis and understanding of the "natural" system?
