I want to make a very important point here, because I think that we've failed historically in New Zealand to manage the issues that would have prevented us from ever having to pass this bill. I think that's a challenge that we can't deal with. We've clearly tried many times to deal with that challenge and we've failed. So I think that the alternative is to put in place a bill that manages the situation that humanity has been unable to manage, frankly. I think that's the greatest challenge we've got in this House.
