> Only if you mean to make the phrase meaningless. I don't think it makes the phrase meaningless. Just a different conception of what is natural, and not one that's unprecedented. For example, the ancient greeks considered things like cities to be part of the natural world (because humans are natural, and humans naturally build them). In such a conception, an unnatural habitat would probably be something like living in isolation (without even close family), which we know has... less than good outcomes in many cases.
