So, how will it affect food imported into the UK not from EU and food & drink and produced locally?
You mean as well as the obvious knock-on from the limited customs-clearance facilities suddenly being swamped, which is one of the whole points of that thread?
Food imported from countries that have EU trade deals (which is most) will no longer benefit from those deals - both financial tariffs and regulatory non-tariff barriers - unless/until there's direct deals with the UK.
Then there's the "Rotterdam effect" on logistics. And, of course, there's staffing issues arising from factory workers and pickers going home, as well as ingredients in processed food, packaging supplies, etc etc. And, of course, increased demand may not be met by supply, if/when EU-sourced products become scarcer and more expensive. And, of course, the environmental impact of the extra food miles.
But it's OK, because we were promised faithfully and repeatedly that No Deal - oops, sorry - An Australian-Style (No-)Deal was a total impossibility.
Well, we will see how this brexit affect the UK food export when it happens. Waitrose food for example are exported to places like Hong Kong for example.
1. It's about import. (Why would EU/EEA countries buy from the UK, when they can just buy from the other EU/EEA without tariffs or non-tariff barriers...? Or from non-EU countries with EU trade deals?)
2. You do know the difference between producers and retailers, right?
Oh, and have a read of this... www.foodsecurity.ac.uk/challenge/uk-threat/ "The UK is not self-sufficient in food production; it imports 48% of the total food consumed and the proportion is rising. Therefore, as a food-trading nation, the UK relies on both imports and a thriving agricultural sector to feed itself and drive economic growth."
It is clearly what many/most people here wanted and it may have been the "wrong" decision but it was what the UK as a whole decided and those that may have a lower IQ than you, a worse education than you or a lower standard of living than you are still people and have the same rights as you do. ("You" being the general case not anyone in particular - we might have used "one" some time ago...)
If you're not at all happy then join a movement to bring around another referendum and do a better job of putting your arguments forward and listening to those on t'other side of the table. In my case I made my final in/out decision when our UK managing director of a large corp IT company wrote to everyone suggesting it might be a good idea to vote remain.
Going around (not you OP just anyone) saying what we should or could have done is not only pointless but perpetuates the belief that you view that issue as being more important than the democratic process itself. You must accept that decision was carried out in a free and fair national vote otherwise we become like certain other developing nations who have never really experienced democracy and if we end up there, Brexit will seem like a walk in the park.
