So what we've done to remedy this is we've actually said that, look, it's no individual's fault. Responsibility for getting it this bad is shared between regional councils, who should have done better to stop it getting this bad—they've had full delegated authority to do this ever since the RMA was passed. But it's not all their fault, because it's very hard and some of it is technical, and they needed help from central government that they didn't get enough of. Farmers are partly responsible—you know, the "polluter pays" principle should apply here. These rivers don't pollute themselves, and it is the increased intensity of farming that is actually the largest cause of these problems.
