Need to punch this one up.
A very common reasoning mistake, especially around environmentalism: that in the absence of humans or some human intervention, there is some Platonic ideal state that "nature" would achieve.
That's not true! Almost all of "nature" is a complex dynamic system - there was *so much change* before humans *even arose*.
If you instead define your Platonic ideal state as {those dynamics playing out as they will, just without humans} then you're just a misanthrope, and you shouldn't appeal to some rosy picture of nature that also conveniently edits out all the disease, violence, suffering and horror that it actually entails...
