Re NZ meat... you'll find theres a lot less truth to the "food miles" arguement if you look at the production systems in the UK and NZ, in the UK, tractors burning diesel plow and plant grain and crops, tractors then harvest grains and silage, tractors then feed that out daily to stock kept indoors away from the weather where they will grow better. Lots of diesel. then they're trucked to the works, the packed meat trucked to the chiller storeage warehouses, and trucked to the supermarkets.
NZ, a guy on a small motorbike whips round the paddocks chasing cows from one paddock to the other every few days. then they're trucked tot he works, packed into containers and loaded on a ship for export, unloaded overseas into chiller storage, and trucked to the supermarket.
There was a study as part of the kyoto agreement data collection on agriculture for CO2 emissions. UK intensive crop feeding meat rearing caused 3 times the CO2 from burning fuel from paddock to plate than NZ Pastoral meat rearing from pasture to plate. even including shipping CO2 emissions from the boats.
Oh yes... You can't blame us for the sausages or bacon either. NZ is a net IMPORTER of pork products, only 40% of our pork consumption is NZ raised, the rest is imported from asian sources as cooked product.
Or was... the goverment has stuck their collective head up their assholes, ignored that Foot and mouth is endemic in asian herds, and decided to allow uncooked pork product in.
I think it's time for a new holiday, Guy Fawkes failed over there, we need a success over here...
