Hon JAMES SHAW: I'd say that I've heard that assertion a number of times but I've not seen any evidence that it is true. If you look at, for example, the work that Silver Fern Farms have done, they have just released a net zero beef product into the US market, which is selling very well, and they're looking to expanding that to other product lines as well. There are a number of farms and farming businesses throughout the country that have actually increased their profitability whilst reducing both methane and nitrous oxide emissions into the atmosphere, and what that suggests, actually, after many years of research and trial and error, is that it is entirely possible for farming to be both more profitable and lower-emission.
