Minister, you've spoken of the oversupply of credits, and I haven't heard that term before except used by you in this House and by officials. Yet when we dug further into the oversupply issue, of that 120 million-odd New Zealand Units which are currently held by participants in the market, 66 million of them are in forestry. What that means is they're, essentially, locked in trees, because if those foresters wish to take advantage of those units and sell them or trade them or lease them out, sooner or later, they're going to have to, when they cut down their trees—assuming that they're not just growing pines for a postcard or for some other reason—pay back those New Zealand Units, unless they replant. So 66 million of those credits are, essentially, locked. They're in a vault. In fact, they're buried deep underground. The carbon is locked. They can never come out.
