There are many benefits to the system that Southland farmers like David run. Exporting unrequired livestock improves efficiency by reducing wastage. They don't need replacement stock to be reared. Live export cattle are wintered on feed pads. Farmers like David have actually reduced the environmental footprint by reducing the calves they rear and graze. Farmers involved in the live export trade provide employment and spend much of their income in their rural communities. David told the select committee that the revenues derived from live exports are used to support the farm's investments and to reducing its environmental impact. And this is the thing, you've got to be in the black to be green. Something that I think Labour, unfortunately, forgets a lot of the time.
