The line between natural and artificial is so weird to me. Like, objectively speaking, petrolium is natural and organic. Are humans artificial? We evolved, we're biological, we fulfill an ecological niche. There's hardly a single environement we haven't transformed. Do we just write off every ecological change since the Bronze age as unnatural?
You're right, what counts as 'natural' is a bit pointless, and perhaps is a question that's not even worth answering. But isolated and unique ecosystems can be seriously damaged by a disease or parasite carried by a stray Northern Hemisphere critter.
This seems so obvious.
