Toward Ecosophy

This idea reminds me of the short-lived 70s sci-fi spoof series called Quark, which included a character named Ficus who was (supposedly) half plant and half human. He looked completely human, but indulged in some plant-like behavior. One episode features him "pollinating" with the human daughter of an evil emperor (who is of course outraged that his daughter should be doing such a thing). I loved the show. So the trans-plant idea is already out there!
