One other point I wanted to make about this is that having altered nature over the last 180 years or 300 years or whatever in New Zealand, we're never going to rectify it without human intervention. One of the very quick examples I'll give you of that is where we've got native wilding pines creeping into all of our North Island national parks—Whanganui National Park is a great example of that—and that's going to have to be removed. It's going to be a very interesting debate in this House when we have to go in there and get them out, because the same thing's going to happen as when we go in and get wind-damaged stuff out. That's my lot.
