The oxford definition gives the condition in the definition: "not made or caused by humans". this is the one that is widely accepted. if you were to ask ordinary people whether a nuclear power plant, a tree, uranium ore dug up, or processed uranium, were natural, they'd say, no, yes, yes, no, because unlike you and brb, they have a good grasp on what the term means. however, if brb wants to hold on to this all-encompassing personal definition of natural, then why use it defend nuclear power plants?
