Earlier quoted context omitted.
You'd be surprised how negligible the environmental impact of shipping compared to production is. As an extreme example, it's cheaper in terms of CO2e emissions to produce and ship lamb from New Zealand to the United Kingdom than produce it in the UK.
How is that possible?
raising sheep requires land, remember? it's livestock, grass/feed, water, veterinarians, medication, sheepdogs, abattoir, compliance, inspection, processing, packing, refrigeration, shipping.
if you're producing wool, let's substitute/add shearing, washing, drying, processing, packing, etc.
not to mention sales, marketing, client relations, accounting, human resources, payroll taxes, corporate taxes, property taxes, sales taxes, value added taxes, etc. because a ranch is a business that turns over probably millions a year.
how much does all that cost in the UK? how much does it cost in NZ? find the difference, and compared to the shipping costs, which are trivial, probably a couple of thousand dollars to get a refrigerated 30 foot container from Auckland to Amsterdam, then another few hundred pounds to get it across the channel and into a distribution center in the south of england.
i don't know a damn thing about farming or logistics, but all it takes is about 2 minutes of thought to see how the economics would work.
