CHRIS PENK: Mr Bennett encourages me to bring him in, but I don't think I would do that. I will just say that a wise man once said that you can't eat trees—or something like that—which, obviously, I suppose, depends what you'd call a tree as opposed to a plant, and I wouldn't know where we draw the line. But in 40 seconds we'll have a good idea where to draw the line. But anyway, that person who made such a profound comment that trees can't be eaten was, I think, alluding to that fundamental tension that we were talking about before—the mutual exclusivity of planting certain types of forest, as compared with farming the land. So I think these are the factors that will go into the test, ultimately, when it becomes an amendment to the law, and at select committee it will be very seriously thrashed out. I'm sure we'll have lots of good discussions there; I welcome the submissions that will come in and the consideration by fellow MPs in that forum.
