Against all this backdrop of the great unknown, we need to understand how will forestry harvesting techniques evolve in the next few years and how diverse will the tree become? In other words, what will it be used for, because it won't just be used for the stuff we see in this building; it'll be used for all sorts of things. There's just such a diverse potential with our tree industry. How many jobs it will create, how much it'll be worth to the manufacturing sector, what impact will this have on New Zealand's red meat sector income of some $12 billion, and if some of that's lost, what percentage of this will be replaced by the forestry sector? One certainty is this will not happen in the next 25 years, because trees' only value to that point is as a carbon sink. So it's, effectively, going to be 25 to 30 years before the trees we've seen planted today are available to the manufacturing sector. At present, the volumes involved and logs available in New Zealand are starting to drop, as the great planting spree of the 1990s comes to an end. So there's so much uncertainty in this sector, and that's a little bit of background information that I want to just put context around why this is necessary, and why I think it adds a little bit to the puzzle.
