We've got the same problem down here. A very left/green leaning government who now seem intent on killing the dairying industry. Despite the fact that the country was largely built on the back of the dairy industry. Dairying makes up 3.5% of GDP, and of the dairy exporting countries we are the top exporter with 19% of world market. Next country down is Germany at 9.8%. USA is 5th with 5.6%.
The green gubberment want all waterways/rivers/creeks swim-able by 20?? So farmers are having to fence off all lakes rivers etc to prevent stock from walking in it/drinking from it. Any fertiliser/milking shed effluent must be treated and not allowed to leech into any waterway. Fines range in the hundred of thousands of dollars.
And then there's the sheep. Back in 1982 we had 70milliom but now we're down to only 40million. They and the cattle all fart ! ! !
