I was at Invermay, just out of Dunedin—just by the way, this Government saved that sheep genomics team from being disbanded. I was looking at their sheep-breeding programme there and their methane-capturing boxes that they put the sheep in. They're breeding sheep that are more methane-efficient, and they're seeing some quite consistent lines in terms of room and size and how that plays out in terms of methane emissions. So there is good stuff happening. Jacqui Dean alluded to lines of cattle that they're now starting to identify. So genetics is a big issue.
