@IsoscelesSandwich yes I agree with a lot of that. It feels like they have realised that they can't both keep food costs low (and they are low in the UK) and make UK farmers toe both the high welfare standards and good for the environment line.
So they are going to make UK farmers toe the environment line and high welfare line, contract out 'food' to other parts of the world where welfare standards are lower meaning food production costs are lower. The average punter doesn't care about country of origin or welfare standards as long as the price is right, and those who do care will continue to pay a premium for UK produce.
Result: The northern British countryside mostly becomes an overgrown scrubby mess. Lots of trees scrub and predators but a loss of ground nesting birds and British uplands farming heritage.
Small commercial family farms become a thing of the past and the hobbyists take over the 'high welfare' sector.
Meanwhile commercial beef units become the norm rather than the exception (much like commercial pig and chicken units already are) and sheep are kept for conservation purposes only and not bred on a commercial sale.
British Lamb, one of the most environmentally sustainable, free range meats going, gets entirely replaced by produce flown from the other side of the worlds here it is mass produced.
The arable areas of England will be slightly less productive, with more wildflowers and hedges round the edges and just as much bunny, deer and pigeon killing as there is now.
