The author of a book says: "Cyndi Schacher - Thank you for your sparkling point of view of the world and those who inhabit her."
---Shouldn't it be "who inhabit IT"? instead of "HER"? So he thanks her for her sparkling view of the world and for all those who inhabit this world (that's how I see it).
I think an author is allowed to personalize the world and consider it as "Mother Earth" - using the pronoun "her."
You could certainly write "it" if you prefer.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
