Let me just give a practical example. Members opposite talk about indigenous species being kaitiaki for Māori. Will members opposite tell me which of New Zealand's 10,000 algae have kaitiaki rights? There are 10,000 different varieties of algae. Section 6 of this bill says that all those algae are covered by "plant varieties", interestingly, the way that "plant" is defined. Members might say, "Well, why does that matter?" Well, let me tell you why it matters. Every member of this House would know that one of the most significant challenges we face is climate change. Equally, this Parliament knows that one of the biggest challenges of that is that about half of New Zealand's greenhouse gas emissions come from agriculture, and one of the most interesting scientific projects that offers us hope of a solution for our agricultural industries is the work that is going on on Asparagospis armata, which is an algae that has the capacity to reduce agricultural emissions by 95 percent.
