Some of it is downright ridiculous
@chas I recall some years ago that Young's closed their prawn processing plant at Girvan as they had figured out it was cheaper (that is they could make more profit) by taking the prawn catch, flying it to the Far East and processing it into Scampi etc. rather than continue to employ Scots processing workers. How's that for 'Eco friendly' using all that aviation fuel rather than paying a decent wage?
As a kid I recall the harbours of Scotland being full of Fishing boats and the coast having thriving fishing communities but then the Klondykers appeared stripping the seas around the coast bare and also under EU rules Scottish boats could be sold, along with their quota, to foreign, mainly Portuguese and Spanish companies, who could then operate from their countries, sail across, trawl our seas and offski with the fish meaning an end to Scottish fish processing plants, Ice factories, Fish markets etc. etc. Britain has been shafted for decades by the EU and no-one even took any notice not even the 'eco' mob. They seem to have been totally blind to it.
