For goodness sake. We ate perfectly well before we were conned into joining what was then called The Common Market. It may be a shock to learn it but food doesn't appear prepacked by European magic on Tescos' shelf - it's produced by people called 'Farmers'. Not only that, British farmers are amongst the best farmers in the world.
They are indeed good farmers. Farmers know that harvesting causes a huge surge in labour needs, and is usually seasonal. There are not enough local workers to do the highly disciplined work required of harvesters. Urban workers won't do the work as it is hard and requires leaving home and living in temporary accommodation. Eastern Europeans are willing, efficient, disciplined, and quitting the UK farms because of Brexit problems.
Farmers now doubt if they should risk planting.
True, robots can harvest pretty well but cannot handle soft produce, and are a very expensive investment.
I don't want to eat US chlorinated chicken or hormone and antobiotic-laden beef and am increasing my cooking skills for vegetarian foods.
Grandad, you and unaware optimists like yourself should listen to what farmers who are the hands-on business men are saying
