MARK CAMERON: Ha, ha! As an active farmer myself, and knowing there are, essentially, no practical operating farmers in the Labour caucus beyond the aforementioned, I'm intimately versed in how my own farming practices affect my own local environment, as does my council. Equally, this could be said of Auckland, Wellington when they're setting standards for local rivers or beaches and the understandings of the effects on their environment. One could offer several examples. My own farm management is seasonally indicative, acknowledging the 1,300 to 1,400 millimetres of rainfall I get per annum. This is taking into consideration the month-by-month variations; the varying soil types, some of which are alluvial and other that are podzol clays; also, the limestone substructure—this is all on my own property, let alone 10 kilometres down the road, and in my local council they understand this. As farmers, we change our practices with seasonal, constant changes, giving consideration to the nuances of on farm and on-farm activities. All the decisions we make are premised on a myriad of localised variations.
